I haven't had a system since 2008 and I've recently installed a double din sterio, amp and subs. Not that I had the best system back then but things have changed, thank you for explaining these basic functions.
I've been doing this shit for 21 years and I'm always thankful for those that share their knowledge with the community. I always try to crack out my DD1 and help people tuning their amps, but I always make a point to explain how it's all working and what I'm doing. Amplifiers are complicated for your average bear and education goes a long way to keeping this scene alive.
Your channel has been very helpful. I'm thankful, so is many viewers here. 🙏 keep it coming brother 💯. I have learned a lot here that never been before.
Killed it man, great job. I watch tons of videos on this genre amd you by far explain things way more understandable than most amd cover it all dude,very impressive 💪💯🤘🗣️ Im no newb to car audio and still can't understand shizzle of what some of these guys are saying really,so,i know it's hard for a novice etc...ty ty
I hope i don't come off weird or anything but i really love ur channel u don't mislead people u just tell it like it is in if someone doesn't like them to bad anyone else that make videos like this or should i say try to make videos like this lie ur a straight shooter and i love it when someone tries to tell u ur wrong about something and u SCHOOL them if they would only realize ur only trying to help ur that are being misled buy other companies so i truly appreciate everything u do for all of us that really don't kno as much so thank u ur awesome my friend (✌🏼💪🏼🔈💪🏼🔉💪🏼🔊)
Concerning the PHASE knob adjustment, you have mentioned in most cases it doesn't matter. You may be right. In some cases makes the world of a difference. I think some amp designers have gone through specific experiences then decide it was actually crucial to put such a knob on every amp they would make. I think in every industry where quality is crucial, there have been are and always be small details which make collosal difference in that particular experience, details understood only by few who have had the pure luck to get it. One of my last experiences in car audio was with the grounds in a car audio system. On the internet there are different opinions on how to ground but never a general idea, you always find different pole opinions. Until you try it yourself. Having a common ground point for all your audio equipment in your car would enable you to enjoy your system how you were supposed to.
Grounds can absolutely make a huge difference. The phase thing is more common to see a difference in mids/highs than in subs. That can absolutely be a huge thing in the upper end of response.
I just received that SAE-1000D! Pretty cool little amp. I really appreciate your explanations bc my stuff was all out of whack. Do you have a video on grounding or fixing ground loops?
I came across an article about subwoofers that were basically powerful fans. It got me to thinking, can you do a TST on exotic speaker types or the various exotic materials, like beryllium, in speakers? Maybe bust some myths on solid silver rca's or other "audiophile" level gear. Anyway, great vids.
You're thinking of servos. That would make for a good video, but in the fashion I do videos I'd need some of those things on hand to be in the video and show things. If I was giving some of that stuff to use in the video I'd gladly do it.
I still think the EMF amplifier is superior however sundown makes a really nice amp. I would like a bigger 4 channel so I can get rid of two of my 2 channels.
my gains are set to max in every way shape and form on the amplifiers side, however my bass gain on my unit is only set to +2db and it sounds fine up to volume 25-31 (depending on the song) people don't understand that you can turn gains up but run your eq on the radio as you see fit. i do not play into distortion and should i ever smell a speaker (again, certain songs hit that "moar power" spot) i dial it back a bit. i turn my tweeters up as high as possible to compensate but i do need an amp just for them. (4.4k bass vs 50*4 tweeter lmao)
I am surprised you did not mention the tweeter trick when setting the gain. Set up a test tone that is well below a tweeter's high pass crossover. Then hook up the tweeter in parallel with the speakers. Turn up the gain until you hear distortion from the main speakers, or anything at all from the tweeter. This works because the signal will not have any content in the tweeter's pass band, but when clipping occurs anywhere, there will be output from the tweeter. This will smoke out distortion even in head unit line out signals - really handy when doing factory radio upgrades... You can even do this for tweeters. Just get a high sensitivity tweeter and make a 12Db/octive high pass at about 15khz and keep your test tones below 10k. Putting a led in parallel with the tweeter can work too, esp if you can't hear tweeters anymore.
Quick question. I just repaired my Rockford 801s and I'm a little lost as to when it's bridged and should I adjust both gain knobs or simply one of them thanks
The owners manual should tell you, but one way to tell is to bridge it then adjust 1 knob, then the other knob. If nothing changes when you turn one of them then no it wont' matter. If it changes when you do both, then yes, you do need to adjust both.
Awesome vid as usually. Question, im trying to tune my rockford 801s. I have it bridged but there is a left and right gain. Which side/gain do i use to adjust the amp. Any help would be appreciated. Thanks and keep up the great work
You should make a video on how to know what soft parts are compatable with what motor/basket assemblies. I've seen builds that have things like sundown soft parts in ascendant audio assemblies. Just something I've always been curious about!
There are literally millions of combinations. Parts are not universal in that all 3" coils fit in all 3" motors, etc. Different cones have different dimensions that will work on some baskets and not others, spider landing sizes vary, just a ton of considerations you couldn't blanket.
@@ddude1595 Generally speaking, manufacturers won't just sell soft parts. We don't, but we'll recone stuff with our parts and others we source. Basically you'd have to measure yourself, source parts yourself, and figure out what will fit. Just because it fits doesn't mean it will be good either.
@@EMFAudio so if it's not too much to ask, whether it's your parts, another company's parts or stock DC parts, what would you recommend for just a general overall improvement on a DC XL m2 15?
@@ddude1595 There isn't a blanket answer for that because every motor and coil combination is different. The quality of the cones and spiders is one thing, the design of them is another, per application.
Great video and deserved 'like'! What Im trying to understand is.....do you set the crossover on the amp, THEN set the decks crossover to 'match' the amp with a slight overlap or do you let the amp frequencies fully flow through and fine tune at the deck? My previous deck had perfect bass, and now my new more $$ deck has such low bass with the same settings on deck. Should I adjust on amp end?
@@EMFAudio THanks EMF...so if Im using the AMP, i just disable the crossover on the deck in the deck settings, but if im using it at the deck, what should I set the AMP to?
so could I use the bass boost to help a sag in a bandpass? like say it's tuned to peak at 35hz and 55hz, but the sag was in the middle, could you technically get rid or at least midigate the drop (within reason of mechanical limits of course)?
Yes and no. Yes you could do it, up until the maximum voltage of the amp. So in the case of these amps having a maximum of 6v, you could use the speaker level made into an RCA jack as long as you didn't exceed 6v. Over that could/would damage the amp.
So I heard you can damage a car amplifier by mounting it to a subwoofer enclosure is this true if so how does the car amplifier get damaged and what happens to the car amplifier when it gets damaged from being mounted to a subwoofer enclosure
If there was a quality unit (similar to the deh-80prs) putting out 6-9 volts could this voltage being clean produce more power?I know the amp can. Put out rated at 0.2-6 volt input but if u have a clean 7-8 volt input would the amp distort it just because of the input voltage being so hi?
The only way it could actually be producing more than 6v is if it was balanced outputs, which few are, and the amp would have to be balanced in as well. If you go over 6v you can fry the preamp on the amp. It doesn't just turn into a bad signal, it's like sending too much voltage into the power supply, it fails. That being said, a clean signal in, be it 0.2v or 6v does not produce more power. The setting is to match the signal to achieve maximum power output capability.
@@EMFAudio ty for the response, I have never seen a radio with a balanced output before seen the plugs on some amps but never seen any be interested to c the pros and cons
@@1-Six-dee I haven't seen any modern units with balanced outputs, I've seen some processors that do though. The only projected potential advantage is reduction of noise. With how RCA's have changed that isn't really an issue, which is probably why you don't see it anymore.

@@FLYGUYFOX Nooooooo don't wire batteries in series. That will add voltage to each one you do. So unless you're replacing 2 batteries in an RV that runs on 24v, don't do that. Parallel only.
@@FLYGUYFOX Putting two 12v batteries in series will have the capacity of 1 battery but increase voltage to 24+v which you can't charge and will likely blow up your amp instantly.
That should also cause the fuse to blow, hopefully quicker than the protection on the amp. That kind of short usually kills a power supply before protect can do anything.
If u want to know u have a good input source get a pioneer deh-80prs, It can play to 90% volume before it ever gets near clipping it is the best unit under 950
@@1-Six-dee not that any people are willing/can spend $950 on a head unit. OP: Essentially gain adjusts your amps output. Most people think that it's like a "volume" knob. That if you turn it up your amp makes more power and vice versa. Not the case. Your owners manual will tell you what your head units output voltage is. And that's what you adjust your amps gain to. Most are around the 2-4v range. And while you can just turn it all the way up and lower you head units subwoofer setting or vice versa that's not the correct way. Best thing is to find the head units voltage output and adjust your amp as close as possible. I hope that helped a little....
If you set it wrong, yes. Remember, subsonic is a high pass so if you set it to 20 hz and the low pass to 80 hz, that will be full signal from 20-80 hz. Now if you set the subsonic to 50 hz and the low pass to 50 hz, yes, it would absolutely kill the signal.
@@EMFAudio we all know how to set amp gain an frequency how to turn up volume 3/4 up an set deck , but when you install let say audio control eqs these are high output or even a clarion preamp or both most pre amp have volume control how do u set gain an frequency on these processor an amp an can you still go up 3/4 volume on deck.
@@wazid0122 For starters, no, we don't all know how to do that, that's why I do these videos. I don't even use 3/4 as a reference, I use the highest volume that is clean which on some is full volume. Setting the gain is the same method with a processor or not, which I could include in the video. I have some other ideas to include as well. I'll put it on the to-do list.
@@EMFAudio and you probably have to order them due to the fact you do not actually keep stock & inventory as legitimate businesses should. People might as well buy from somewhere else & get their order faster. Instead of ordering from you then waiting on you to order from your so called 'supplier' and then the two or three days it takes you to get it. Then another two or three days for the original customer to get their order after you finally ship it. It's like the two 4 channel amps you told the guy in another comment you had in stock and could ship immediately. Lol first off you sounded desperate to make a sale. Second, you are supposedly a business that sells car audio gear and you only have two 100.4 amps in stock... You really should close if you aren't going to keep full inventory and stock because you're adding nothing to the car audio world. You are not filling a void. You're just one of those people who are in the way just messing up things for other people. Go get a regular job and let the real pros keep the industry going. No wonder you talk bad about other companies & people. You see them doing so much better than you and accomplishing things you can't even dream about. You are full of jealousy and envy. Nothing but a hater and you've proved it in so many videos. For instance your videos on Steve Meade, c'mon grow up already. Everyone knows who Steve Meade is because SMD has helped so many people and contributed so much to those who love music and audio. Yet so very few have heard of you. Wonder why Meade has friends and real business investors like Gately, SHCA, D' Amor, B2 Audio, Sonic Electronix, Deaf Bonce, Sundown, Skar, Audio Legion, XS Power, DC Audio, Mechman, AudioControl, Second Skin, SoundDigital, Pride, all kind of different celebrities etc and so on. The list keeps going. Then there's you little old EMF who doesn't even have inventory of his own subwoofers or amplifiers and only had two 4 channel amps in stock that he was eager to solicit a sale via RU-vid comment. Seriously how are you going to hate on so many other people who are actually contributing to the industry when you yourself are making zero progress. Here's a tip how about focusing on your company and actually building a solid reputation. Then you might actually get your business up off the ground and see it grow wings. You will never be a success if you keep spreading negativity. You're making too many enemies. Need proof... Go to the next SEMA show set-up a booth & let Steve Meade set up a booth 20 feet away from yours. Both of you take your products that your company offers and take plenty so you can do giveaways as a thank you to supporters. Whose booth will have a line wrapped around the building while the other has no line at all because nobody knows who he is and he has zero product to even take to put on display at a booth??? Hmmm, you know the answer to that question and it eats at you every day. Ok go ahead and attack me in order to boost your own depraved ego. Go ahead and mention how my comment was so long and blah blah blah. Lol yeah I spent every bit of two minutes on this comment... Remind me again, how many videos and how much time was it that you spent directed towards talking about Meade and his SMD products? Oh yeah lots and all that time spent made you look like a complete fool, the joke ended up being on you and only caused several car audio RU-vid channels to actually make a video disproving several of the videos you have made and go into detail in how you were wrong on various videos you have wasted time doing. EMF stop being a hater, grow up and learn some humility. Find your own lane and do your thing. Stop focusing on negativity. People get sick of it quick. Alphasonik makes better car audio products than EMF and Alphasonik just recently got their business back up and going again after being closed for several years. Think about that when you can't sleep tonight.... Alphasonik is far superior to EMF, FACTS. Good day sir, wish you nothing but the best.
Gain matching and phase matching of multiple amps on an oscilloscope with no load and then with subs wired video? Possible termlab scores for comparison. Test A: Gain matched only with no load Test B: Gain and Phase matched no load Leave gain and phase settings as is and wire subs. Test C: adjust gains if necessary with amps under load. Test D: adjust phase if necessary with amps under load.
The tricky part to that is having a vehicle with multiples of the same amps and multiple subs to benefit from phasing. I don't personally own anything that would be able to properly demonstrate that.
Passive means nothing is changed from input to output, that is literally the definition of passive, passing signal. If there was nothing come out, there would be no reason to have it, because it would do nothing.
@@EMFAudio Honestly, I don't don't remember what I was thinking about when I posted that. I was pretty lit. Damn Vodka. My bad. It's all good. Love ur videos.
These are some very nice amps . I wouldve used zapco myself but either way who the heck are these people asking you about amp settings . Omg if you dont know what gain,lpf, hpf, what channels inputs r for ? wtf? subsonic filter , a lot of lower end amps dont have that setting but if you dont really know that please please start a new hobby
When doing an amplifier explanation video why would you pick an app that no one's likely to own no one's likely to purchase and give a bunch of explanations they're so over-the-top the 98% of people aren't going to understand anyway you can save that for the high-tech version of an amp exclamation video
Impedance is dynamic, that changes in a magnetic field. I think you're thinking of resistance. To answer your question, resistance difference isn't what will effect performance. CCA can't handle the current OFC can. So, as long as you aren't exceeding the current capabilities of the CCA wire, you won't see a difference. If you exceed it's limitations, yes, you will see a difference.
Yes you are right I was thinking of residences . so with 4 runs of power 1/0 cca and 4 runs of ground 1/0 cca,I should be okay on a American Bass VFL COMP 5k?
