Nah he means kicker, he wants you to buy there stuff. If it where a “wire comparison booth” not a (kicker booth) he woulda said buy some kind of official ofc wire true 4 gage or greater for a 20ft run with this wattage system don’t go to Walmart.
I used knukonceptz KCA (oversized CCA) 1/0 for my feed from my xs power battery under the hood to my second XS power battery in the back and big 3 upgrade. I've got 2 stinger voltage meters, one in the front and one at the amp that I set using my klien DMM. I'm getting the exact same voltage at the front and back, give or take a point or two. The CCA seems to work just fine for my 2k RMS amp pushing the soundqubed HDC 1,500 rms sub.
It does. This test is BS. These are advertising/marketing campaigns guys. Please wake up. 99.9% of the time they are rigged. Use a 0g CCA and let's see how it does. Oh it's not the same guage as OFC? No it's bigger because the flow rate is less but it's still CHEAPER and just as good in the proper guage for the power level. Let's get rid of elitist fluff and stick to the facts please.
They used "cheeseball" CCA wire, but if they used a quality CCA wire there really isn't much difference other than potential thermal runaway, and just use properly sized wire and youre fine.
Actually you paid for 400 watts, you're getting 397-398 with cca wire, be nice to know if you used the same gauge for both, since you neglected to mention that.
IDK, their is alot of people that say using CCA, there is no loss of voltage. But it does make sense to have pure copper instead of 75/25 CCA. Im going all OFC, instead of CCA.
measure the inductance created by those coiled up power cables and take that into account as well. It's no secret that OFC is better quality. The question is it worth twice as much money. I think if it was, there would be no need for these types of demonstrations. I believe this is a fudged up example.
People buy aluminum coated wire being cheap. Oxigen free copper wire doesn't corrode like aluminum wire does you make more power with copper wire anyone watching should realize the gains from a one time purchase
@bassbuildscarlmeadors6650 copper is one of the highest nonferrous corrosion factor metals out there. Aluminum corroded far less than copper... If you're gonna comment at least know what you're talking about
I actually wired my truck up with 4 gauge CCA to the distribution block. Measured voltage at the battery was 13.36v and measured voltage at the amp was.... 13.36v powered on. I have about 12 feet of the 4 guage and then the distribution block, and then about a foot of 8 guage to the amp, with an inline fuse in between. No voltage drop at all from the battery to the amp.
Test is not telling you what guage wire there using. You can use CCA wire just have to up the guage a bit. If it needs 4 guage use 0 it will surpass the differerence.
Yes its worth it if you build the system for competition.. I got 0ga cca for $30 whole amp kit with RCA wire. My wifes step dad go a kicker amp kit for $85 on discount at best buy and it didn't come with RCA'S. I will keep my lil bit of watts lost for less then a fraction of the price unless its for competition.
Bullshit. Kicker sells only one kit without RCAs at Best Buy and it's nowhere near $85 full MSRP. Second, I also call bullshit on your $30 0AWG CCA kit. No full 0AWG kit is $30 unless it's no-name under-gauged bullshit. Provide links or STFU!
@@firebirdude2 hey you dumb fvck punk ass bitch. I just bought a 27$ 0ga amp kit from Amazon and it's got everything I needed. So next time you want to look cool or knowledgeable, figure your shit out before you end up just looking like a dumbass. And yes it's been a year since you commented that. Oh well, a year later and you still sound like a douchebag.
Obviously OFC is the more superior cable here but it’s only necessary if your system is pushing over 2000 watts rms also if your doing short runs of CCA from say a sound battery in the trunk to your amp and you do dual runs of 1/0 gauge wire you should be fine I use a combination of both OFC and CCA using the OFC to run from the battery in the hood to the battery in the trunk
Gp merica no b.s. for every 9inches has almost a full ounce better copper content than sky high, and most notably doesn't come pre corroded from factory. Cheaper too lol. 99.99 percent pure copper certified and made in USA for the win
Mike NBass or you could purchase the most copper per foot for the least amount of money which is 2/0 welding cable which has strict standards it has to pass to be certified for use unlike any car audio wire...
it make a huge difference? ive got pretty strong electrical but with my jp63 at 2 ohms it still absolutely destroys my xs4900 and 280 alt which i find so weird and can only blame on amazon cca 0 guage wiring XD
Not true results. I just tested my battery up front and got 12.85v. Then i went back to my amp and checked and got 12.85v. And i have cca wire Soooooooo
There's nothing wrong with CCA wire. Aluminum does have higher resistance than copper, a known fact.. So if you choose to use CCA wire you need to do some math and figure out the proper size wire to use... It will be larger diameter than OFC to achieve the same current carrying capacity. Nice sales job, but it's just that... Trying to make you think you NEED to buy expensive kicker OFC wire... Do a proper job of engineering your system, and CCA will do every bit as good a job as OFC.
What Gregg is saying is correct, you are either not reading what he is saying or dont know better. The resistance in aluminium is about 40% higher than in copper, so yes using the same gauge and length of cable (like this test setup) OFC is the clear winner. But often u will be able to run 2 x 2/0 awg wire CCA in pair cheaper than 1 x 2/0 awg wire OFC, while having less resistance and lower voltage drop. i doubt corrosion will become an issue before unless your planing on keeping the same cables in place for 10+ years. This is also why u see some newer industrial facilities using 150mm2+ aluminium as mains in, over 63mm2 copper cables, duo to cost.
Here is a recent article on CCA for power transmission that gives a short result of 50 years of testing in 100,000 homes: www.jadelearning.com/newsletter/2017/05/Copper_Clad_Aluminum_Conductors.php
mattemerine199 you're the IDIOT! YOU ARE SPEAKING AS IF EVERYONE OUT THERE IS AN AUDIOPHILE OR RUNNING A 20,000 WATT SPL COMPETITION SETUP. THE FACT IS THAT YES WE CAN ALL AGREE THAT OFC IS WITHOUT A DOUBT IS SUPERIOR TO ANY OTHER CONDUCTOR. HOWEVER, ALUMINUM, BRASS, GOLD, PLATINUM ARE ALSO CONSIDERED GOOD CONDUCTORS. CCA IS ADEQUATE FOR MANY CAR AUDIO APPLICATIONS AS LONG AS YOU FROM A REPUTABLE MANUFACTURER WHO USES PROPER AMOUNTS OF COPPER CLADDING AND GENERALLY HAS MANUFACTURING PROCESSES TO PRODUCE A WIRE THAT INCLUDES ACTUALLY MEETS TRUE AWG STANDARDS. ALSO VARIANCES IN STRAND COUNT CAN AFFECT BOTH OFC AND CCA. MANY MANUFACTURERS MAKE OFC CLAIMING A CERTAIN GAUGE BUT IS ACTUALLY UNDERSIZED. THIS OFC IS NO BETTER THAN A CCA IN THAT INSTANCE. A GOOD CCA IS CAPABLE OF BEING EQUIVALENT OR VERY CLOSE TO A PARTICULAR OFC IF IT HAS QUALITY COPPER CLADDING AND AN INCREASE IN STRAND COUNT JUST ENOUGH TO MAKE UP FOR THE RESISTIVITY OF THE ALUMINUM. TYPICALLY FOR 1/0 YOUR TALKING ABOUT SOMEWHERE AROUND 1000 STRANDS OR AN ADDITIONAL 20%. ONLY INCREASES WIRE DIAMETER BY 5-10%. THIS WITH GOOD COPPER CLADDING WILL MAKE A CCA CAPABLE OF HANDLING ABOUT 85%-90% OF OFC BASED ON CONTINUOUS FLOW. THE CCA ACTUALLY MAY HANDLE INTERMITTENT BURSTS OR SURGES BETTER. KNUKONCEPTZ MAKES 1 GOOD EXAMPLE OF THIS TYPE OF CCA.
Keep in mind that ensuring your wire is OFC is only half the battle. Manufacturers FREQUENTLY short change the actual amount if wire and just use thicker insulation. So "4 gauge" is actually closer to 8 gauge once you cut it open. And this is a rep for Kicker. It's their demo. Leave him alone.
firebirdude2 There's a reason I said AudioTechnix. It's the same quality if not better but for much cheaper. With kicker you are just paying for the name, although I'm not sure why someone would pride them self with owning a kicker product.
firebirdude2 if you buy as "ga" then they consider the whole wire "insulation plus copper as whatever "ga" if you buy "awg" they only measure the actual copper gauge. I think or at least thats how i see it.
firebirdude2 Its thicker than most CCA wire out there. Basically the same size as kicker. Underground brands like knukonceptz, sky high and the old audiotechnix have their wires a lot cheaper and have amazing quality to them and can easily go evenly toe to toe with rockford and kicker, actually they have more strand count then rockford or kicker, same size though, so flexibility is one advantage.
LOOK CLOSELY - I may be wrong, but.... Dual (OFC - BLUE) and Single (CCA - RED) on the positive battery terminal. Single OFC and Single CCA running to the distribution block. Single OFC running from the distribution block to power the amplifier. Yet, they can magically get two different results from the same connection...
No, stop that myth. DC electrical is based on current, "skinning" means nothing with current. Aluminum is 60% more restrictive than Copper for current. en.wikipedia.org/wiki/Skin_effect
what is a better conductor, gold or nickel that your amp has on its terminals, or any clean piece of copper? Answer, copper. So this ofc is bullshit...Buy 00 welding cable for less then 2$ a foot
Has anyone noticed that there are 2 Kicker blue wires and one red wire connected to that batteries positive terminal???... Also, if this was a fair test you would run the wires separately from the battery straight to the amp. No dost. Block. And one wire at a time to battery. There not isolated otherwise. Even with the switch supposedly controlling what we can't see. What I do see is that switch can't be isolating the wires if all wires are tied to the battery then meeting at a distribution block as 2 in 1 out to amp. And why the 2 Kicker blue and 1 red at battery... Something doesn't add up.
Something has to power those 7-segment displays numbnuts. I've seen this display in person. You can follow the wires behind it just fine. The test is legit. If you don't think you'll drop 1.5V through 17ft of underspec CCA, have fun putting out the flames.
I had cca ebay wire for 22 years now in the same car and guess what my system sounds good and having had a single problem over the years why pay high dollar for a name
Welding cable isn’t actually oxygen free copper (ofc), however it is 100% pure copper which is far superior to cca. Just as good as ofc, you just gotta make sure you weather proof the terminals so it won’t corrode. Anyways, that’s what I use 👍
Bad test: the size and type of CCA and OFC not specified. CCA can be used but you need to know what you're doing. 2.5 square mm wires for CCA are equivalent to 1.5 sq mm OFC. Your milage may vary but your volts should NOT.
Damn I bought the CCA wire it was for a work truck it's only for a skar RP 2000.1 I'm going to wait skar evl 12 also got the skar 150.4 going off of four sets of mids and highs it wasn't a lot of power I even got a 2 farad capacitor but I think I should have would hate and spend $100 for a decent gauge
I hope you bought oversized cca like knuconceptz or sky high to compensate. Bro that amp is no joke it could start a fire be careful. You should be running ofc 0 gauge
Personally I use 0 gauge copper coated aluminum wire in my small car as it's more than capable of powering my less than 3000w system, especially combined with a 10 farad cap. I see a 0.00v drop compared to the battery in the front with a reasonable load. Also having the wires hanging in a coil as shown on the video will induce a current\lead to increased resistance/high voltage drop. I see the kicker brand wire with extra insulation that could give more performance.
a 0.00v drop, or no drop, is impossible. You will have voltage drop, always, between the fron battery and the amp. If you had 0 voltage drop than you somehow managed to find or make 100% efficient power wire with no internal resistance. You should really let people know about this, you could change the electronics industry. Can I have some of your magic wire? Im so sick of having a .5v drop across 12ft of cable because my 1/0 guage wire has an internal resistance of 0.15, darn, really wish I didnt have that pesky internal resistance that ALL WIRES HAVE. Can I have some of your magic wire?
richard- where can i see more detail for your car audio build? my last build was 10 years ago, as a noob. Im installing amps in my 2 cars- subaru forrester inherited from dad, using an older JL Adio 300/4 amp, (75 rms continuous x4 at 4 ohms), 4 older of MB Quart 3.5 inch speakers, JL audio sub box (2 of 12 inch in their box) kenwood sub amp 650w x 1 rms , 4 ohm. all were taken out last year fromf my prior install done10 years ago. hooked them up using a pyramid dc power source, all the equipent work, except Il prob leave out the capacitor from the old build. 2nd car, 2014 mustang JL audio xd 700 amp( 75w x 4, 4 ohm, 60 rms continuous), 4 of jl audio c5 650 speakers all around, jl audio wedge 13 inch sub box, same kenwood 600w x 1 rms sub amp
I really don't understand the point of bashing each others wiring brands/gauges.. Everybody has their own opinions on their wiring brands/gauges etc obviously.. Run what you want to run and let others run what they want to run, because that's going to be the end result anyways.. It's just a demonstrational video explaining a difference in wiring materials.. It's not about the brand and how much you pay for it, damn.. Just run what you want to run and shut the hell up..
Demo: CCA wire = 0.047ohms. OFC wire = 0.0125 ohms... I call bullshit. There's more than wire composition difference here. Bump up the CCA a wire gauge.
@@Raymo2u yes it appears they have two blue jacketed ofcs and one CCA is possin6le.somewhere in that jumble of ofc two cables becomes one. So its as.if run ning a 2g ofc vs a under gauged CCA 4g
not bad. though it would have been better to see him put the wire connectors on there him self and not use the distributor block. (You know for the non believers out there who believe every one is trying to cheat them) but i see. was that scoche power wire?
You end up with less power and chance of burn up. I've lost amps subs capacitors and all kinds of other more expensive peices because of crap cca. At the end of the day it is only good for the first week or so. Once you heat cycle it. Cca is crap
@@josequilez5449 that's not true. Cca is just fine if you crimp and heat shrink it properly it'll last years. I currently have 2 runs of 1/0 sky high cca going on 2 years now
@@hausboxes I’ve been running 4ga CCA wire on a 1200W Rockford Fosgate for 7 years. 😂 I gotta replace it now tho. Got a nasty voltage drop but I’d say 7 years was worth it considering how little I paid for it.
I switched to ofc and it makes a big difference. My bass hits for 40 sec on a cca then shuts off due to voltage drop. When change to ofc, my bass hits loud and doesn't shut off.
Wow, a comparison between copper and aluminum wire.. Thought this from the title was a direct comparison of OFC wire and copper wire of the same AWG. This test does nothing to show the difference OFC makes over Copper wire.
CCA is cheaper to produce and sell, people see cheaper cable and think it's all the same. OFC is absolutely better than CCA, in every way. This test is BS though, some call their cable 8ga but it's really more like 10 or 12, this is undoubtedly one of those manufacturers cables.
cheap amp kits. length of wire doesnt matter. Should always use same brand and type of power and ground for optimal results. you could see a slight voltage drop but they know that their kits are not being bought by audiophiles.
OMG….What they proved here is Building Code 101….When sizing a circuit you need to go down in gauge when using Aluminum wire because of the lack of conductivity. So if your calculations show you need 4 AWG, yea use that for copper else use 2 AWG CCA, you won’t see that drop. With that said I do prefer copper wire but not for this snake oil presentation.
This seems dishonest to me. Let's see the CCA jacket. I've seen some cheapo jackets that were over half the thickness of the wire. U should compare sky high CCA to sky high ofc or kicker CCA to kicker ofc if kicker CCA exists.
Look at how much of the "cheesy" wire is being used after having gone through 12 feet of the kicker wire then the distribution block.... There is only 4 inches of kicker wire coming from the distribution block... And if you look closely the red wire isn't even hooked up to the amp this is suck bull
Robert, you need to look closer, both wires are equal in length and are connected in the same fashion, they are being switched though a high current relay behind the display. You can see the red power wire connected to the battery terminals. Please reserve comments for something you know as FACT.
BAD comparison, but true. You can't compare aluminum with copper. The impedance on cobber is 0.00175Ω*mm^2/m and aluminum is 0.03Ω*mm^2/m. The main reason for voltage drop is the ground. The voltage runs from the negative terminal on the battery to the positive terminal. If the elctrical system is badly grounded, voltage is dropping. God tip: BIG 3 in the front and ground the amp/s on two places. Left and right side in the vehicle.
re your commnt from 4 years ago, ofc vs cca wire- where did you get the idea of ground yr amp to 2 places, right & let side of vehicle? makes sense, but never saw this. can you suggest web sites where we can learn more re: a good install . also, given my smaller watts installs, is ofc wire vs cca wire worth the price diff. probably, a yes, always, given my good not great equipment. was was initially to use 12 gauge knukonnect wire, but may change to16 ga knukonnect wire, since I have both wire sizes. only because 16 awg dweeules seem to fit better in my jl audio amp. Im installing amps in my 2 cars- subaru forrester inherited from dad, a JL Adio 300/4 amp, (75 rms continuous x4 at 4 ohms), 4 older of MB Quart 3.5 inch speakers, JL audio sub box (2 of 12 inch in their box) kenwood sub amp 650w x 1 , 4 ohm. 2nd car, 2014 mustang JL audio xd 700 amp( 75w x 4, 4 ohm, 60 rms continuous), 4 of jl audio c5 650 speakers all around, jl audio wedge 13 inch sub box, same kenwood 600w sub amp
this is stupid, we all know they used some garbage cca wire thats more like 10 gauge wire on the inside while the kicker is 8 gauge ofc. Put a legit oversized CCA wire vs that ofc and you'll see little to no difference. Only time you'll see a difference is when you draw more current then the wire is designed to handle only then is when CCA starts heating up while OFC will have more stable temperatures.
stick to cooking chef cause you obviously have no idea about anything else did anyone learn the conductivity of their elements in high school ? obviously not here's a chart to refresh your memory thou chemistry.about.com/od/moleculescompounds/a/Table-Of-Electrical-Resistivity-And-Conductivity.htm so your above statement is total bull copper is the second best conductor on earth second only to silver and kicker wire is tinned with silver which also increases it conductivity and reduces it's resistance. My teaching lesson is over but if you have anymore questions about anything electric let me know. I have been installing car stereos professionally since 1994 and was MECP certified the same year.
D Mcd conductivity can be overcome with surface area aka strand count, Why do the main power lines going to each house use CCA? its huge its cheap and it still works why? surface area. 2 runs of 1/0 CCA will be cheaper and more conductive then a single run of 1/0 OFC. Learn a little bit about wire first before you talk Jr.
maybe you should research the difference between AC current and DC current idiot. DC current does not care about surface area. There is NO skin effect in DC current! I know my wire and about both types of current. Here is the wiki about skin effect en.wikipedia.org/wiki/Skin_effect which is your surface area theory blown to hell. I will say 2 runs of the same size CCA might be able to carry more amperage than one of the same gauge Kicker silver tinned copper but you also have to terminate double the times compared to one wire and that would be where you run into the extra costs that would negate any savings found in the cheaper wire. Further more running 2 wires would also cost more labor/time and would not look as clean. There is a reason we use the products we use and pay the money for them that we pay. That reason is because they are the best most efficient solution to product we wish to purchase.
D Mcd You pay the premium because they know people like you will pay more, when in a blind test you'd never be able to tell the difference. You pay for "facts" and "numbers," not audible quality. And hell, even if you're right, I don't want to believe a word you're saying because you're being a colossal jackass. I feel like I'm back on the playground.
I made my point very clear to a block head it took being a elementary to do it but I think I got thru finally and after doing some more research on the matter even in AC current you have to go up a full AWG size to make up the difference in conductivity loss for the CCA and since odd gauge sizes are not readily available this would mean the difference in running 8 ga copper or 4 ga CCA so I don't think even then it would be feasible to do unless your doing a huge industrial building
SAVAGE I couldn't agree with you more. I'm running the RWK01 kit and a RFC50F capacitor along with a 450 amp alternator built by Michael Singer and Rockville's RXD-M5 and their RXA-F2 amplifiers! Two pair of JL Audio C2-650's and 2 Alpine SWR-12D2 subs in a custom ported box. Not only is the sound crisp and Crystal Clear, the bass is unbelievable. I have compared my system to a few of my friends who are running Rockford Fosgate and kicker amplifiers who also spent thousands of dollars more on their systems and they don't even come close to the power and sound of my car. Rockville all the way!
huh? you bought a 400 watt amp and you are getting 400 watts.. you are getting what you paid for nothing more nothing less. The bonus is if you use the more expensive wire you get a bonus of an extra 100 watts..
@@firebirdude2 dude is a dumbass. Just because kicker amps are usually underrated doesn't mean with CCA wire you are getting what you paid for. LOOK AT THE VOLTAGE! If you put this up to a true 800w rms amp(say a pioneer) and you used CCA you would probably only be getting 600w. Just because the amp says 400 and you got 400 doesn't mean you are getting what you paid for. The amp is underrated so 500 is getting what you paid for.
That is what the whole test is about... It shows that buying copper coated aluminum wire is cheaper but leads to an actual voltage drop / drop in efficiency compared to the more expensive oxygen free copper.
This makes zero sense. A different conductor type won't carry as much amperage at the same gauge size. Wow, welcome to fucking electrical 101-101. What you should do; is show a comparable CCA wire, and OFC wire, and give the benefits such as: Smaller wire gauge at the same amperage. Easier to run... Because again smaller wire gauge. Cost savings. If you are buying a larger gauge wire, it costs more. However CCA is much cheaper than OFC, or just straight copper. So THE ONLY WAY IT MAKES SENSE to advertise the OFC wire is; at a smaller wire gauge you get the same power, easier to run, and the same or lower cost, or a comparable cost that the other benefits outweigh. Wire doesn't just "Magically" make more wattage; and saying shit like "Simply because it's OFC" should send fucking red flags.
where in the fuck us that red wire even running to. and no battery charger . uses his product first and then im not sure what is running on the next part cause that red wire is not connected to the amp. just lost all respect for kicker well the little respect i did have for them witch wasn't much to start with..
Looks to me that the switch is hooked up at the little distribution piece then has kicker wire from that to the amp and both are hooked up to the battery they just go behind the panel and back through together
Look @0:17. You can see both power wires connected to the battery. They run inside the display board and then ultimately to the distribution block. Pretty damn obvious to anybody with two eyeballs and the common sense of a NYC rat. Posts like this make me lose "the little respect I did have" for humanity.
