Paused @ 6:11 this doesn't apply to Honda owners or anyone else who is grounding in a unibody. The entire car is the same ground. There's no frame so don't freak out when you can't find it. 🤬🤔. Thanks Jacob!

@crow-vz5lx 4 года назад

Yeah. I have an 01 Civic. I just kept the existing wires. Just added 4 guage to them. Use a wire brush the the contact points.

@crow-vz5lx 4 года назад

Also doesn't matter. The battery is your source voltage and ground. No matter the car. everything that's "grounded "goes to your battery. So you really do need a good clean circuit with little resistance to ground.

@willyvette76 Год назад

And here I always thought the big three was upgrading the wiring (everything just described) as step one then upgrade your alternator to a high amperage model as number two and finally upgrade your battery as the third and an optional forth of installing a high Farad capacitor to the positive side. But I looks like I was wrong. I mean upgrade the wires without the other two isn't that big a priority as the stock system is set to fully handle the stock output of its alternator.

@crow-vz5lx 4 года назад

I think, 4 guage is fine for the majority of people. Just get good quality wire. Most people don't need 0 . Cause, most people aren't hooking up competition sounds systems. Many thousands of watts. I get it what you're saying, but if the power requiment isn't there, than it's ok to have thinner wire. 4 guage is way fatter than stock anyways. The stock wire is a joke for sure, and for some reason, the ground straps aren't even insulated!? But. The other critique I have is the 4th upgrade. To me it seems like it doesn't do anything. The way I'm thinking about this, is that the alternator is already grounded. It's bolted to the engine. And the engine is already upgraded from the ground strap to the chassis . and the negitive terminal from the battery to engine. It's basically part of the engine, in terms of ground. I personally don't think the forth would matter. It just seems like a waste of material. I'd like to discuss this further if you want

@davidtucker4921 Год назад

i used 4 guage i only got a 1200watt amp i dont think i need 1 gauge yet

@justforlaughs8988 3 года назад

Your alt is your source of power and your battery is just a reserve your ground is the most important more so then your positive when you run your wires guys try and run double the grounds and your chassis is on average only good upto carrying 500amps of current so if your running big amps double up on your ground wiring and run it straight to the back of you have a rear bank DONT rely on the chassis your amps and reserve banks will thank you the most efficient you can make it the more power you will put out

@biggklown7644 2 года назад

I have a question or 2 about my set up. I bought a Skar EVL15 D2 and a Skar RP1200.1 monoblock class D amp. According to the owners manual and customer service at Skar, 4 gauge wire is required and Skar told me I wouldn't need to run a second battery or upgrade wiring. I hooked everything up. Grounded my amp to the chassis under the back seat bolts. Both power and ground are 4 gauge, but it's CCA wire. It's a DS18 amp kit. I first had the sub wired to 1ohm with the speaker wire ran straight to the amp. So whenever hard bass or the volume was to high, the amp would go into protection mode. Tested at the battery, the alternator, and at the amp. My volts ranged from 13.8 to 14.3. So my question is, if I'm in the right voltage range, then why would the amp go into protection mode? So then I rewired the sub to 4ohm and I still had the same problem. I checked into the alternator a lil deeper and I believe my voltage regulator is going bad in the alternator. So my other questions would be, do you think if I buy a new OEM alternator would solve my problem with the amp going into protection mode? A lot of people have told me to upgrade my wire to 0 gauge and run a second battery, and do the big 3. But all that seems excessive to run a 1200 watt amp that's 1 ohm stable. I'm sure I should upgrade to OFC 4 gauge wire, and it's ALWAYS good to do the big 3. What is your opinion?

@JacobViral2 2 года назад

Sounds like your amp is at its limit being maxed out and goes into protect from clipping and exceeding it's limit. Make sure to use a voltage meter like this amzn.to/3FyyLWV to monitor voltage as you play. You may want to do a 0 gauge ground run from the alternator to the back and not ground to the vehicle, also do the big 3 and confirm your amp is tuned right and not maxing out.

@biggklown7644 2 года назад

The amp isn't the problem. It's not maxing out like your thinking. When it was hooked up in the car, I couldn't use any of the settings. Everything was turned ALL the way down. So when the volume was to high and a hard note would hit, it was pulling more voltage than the car could produce. Also, Skar customer service assured me that I shouldn't need a second battery. But they did recommend that I at least upgrade to OFC 4 gauge wire. So I'm gonna start with the alternator and go from there. The only thing I haven't mentioned is, at the time I had the amp hooked up, the sub was new and wasn't broken in. I was trying to set the amp to a setting to brake the sub in when I found the issues. Since then I've been running the sub on an old school Lanzar Vibe 1000watts class a/b amp for 6 months or more. So the sun should be broken in. Plus it's been wired at 4 ohm this hole time. When I first wired it up, I wired it at 1 ohm like the manual said to. Then when I found the issues I wired it down to 4 ohm and have left it there since. I plan to run it at 1 ohm once I get my issues fixed. I researched for several months and corresponded with Skar untill I found this combo. They told me that it was a perfect match for what I wanted. Which is the lows and SPLs...lol

Is upgrading the alternator ground; also, upgrading the engine block ground since the alternator is grounded to the block? A lot of videos I just watched, refer to the alternator ground as the the engine block... I will try to do like your showing, I agree with your explanation. For certain reasons I just want to get away with the big 3 for now.

@JacobViral2 4 года назад

Double up and do both as doesn’t hurt to overlap grounds really.

@chavycash2518 4 года назад

Hey Jacob i have a question. I have 4 dual 2ohm subs in 1 box. I currently have 1 ns1 on all 4 subs wired at 1 ohm. I want to add another amp so that i can have 2 subs at .5 to each amp. Question is do the amps have to be the same? I have 1 ns1 and want to get a salt 8k. So It'd be 2 subs running off of an ns1 at .5 ohms, and 2 subs running on a salt 8k at .5 ohms. Thanks.

@JacobViral2 4 года назад

You can do that BUT You will always have more power going to one amp set then the other unless you battle it with some real world testing and tuning of gains for say a burp but in music it’s going to be beer impassible to line up. I’ve seen a lot do multiple amp configs in the same box but you can always see some subs move more then others.

@davidschreckengost7959 5 месяцев назад

First off . On a standard system u check voltage at battery and the wiring in the back if your less than .5 voltage difference then your ground location is ok. Second always look for factory ground to run off of. There made to give the best current flow. Inside vehicle you clean each location and use dielectric grease. Fourth by doing these steps you shouldn't need to run wiring all the way to the back, just to much. That's for 10000 watt or more type systems in witch case you running a hole battery bank in back so you won't have to run more than one run of positive and negative to the back. Lastly when doing outside connections after cleaning the contact points use a clear clear coat to protect them. If your going to do the trouble of the ( big 4 ) you should take alternator off and clean the mounting location before connecting wiring and then use the clear coat to protect.

Probably a group 34 agm like amzn.to/3ViRq0I under the hood and group 31 agm in the back. If not amazon, checkout www.down4soundshop.com/accessories/batteries/xs-power/?afmc=z2&

best advice at @4:46 amen brother If your Car audio works without grounding your engine and just with your battery hooked up, upgrading the ground wire on your engine is pointless, that is for your ignition system-but if only ground point for alternator....noted, it is needed it supplies all the power, battery just stores it........ that being said You better fuse any power wire upgrades, as their lower gauge is in effect a fuse of it's own.... 0 gauge will burn the house down if shorted, fuse all nearest the battery you can

Never answered why you should do it😂

@JULIANysuHOHNER 2 года назад

If a have a 4gauge wire is still worth installing a big 3 with the same 4gauge wire?

@JacobViral2 2 года назад

It would work but suggest 0 gauge amzn.to/3rp2XxG

I just do not understand why, the big three. What is the purpose? Thank you

@no3mun0z 4 года назад

It's if you are going to use a lot of power. Small wire will melt with too much power. Imagine a garden hose connected to a fire hydrant.

@thequietkiwi 3 года назад

It is to lower electrical resistance so your aftermarket stereo/sound system can work to it's full potential without roasting your car's wiring.

I wouldn’t leave that engine ground hanging down like that, I’d look it and ziptie to factory wiring. Also, did you not in-line fuse your power > alt wire? I have a Honda with the stupid ELD sensor so idk if it’s going to help but I’m gonna try it anyways, good video though brother

Would do big 3 but my Ford Focus makes it nearly impossible to get to the alternator in the first place still hold over 14v on over 3k tho that’s only doing extra ground wire.

@ChaosTherapy719 3 года назад

Some cars don't need a big 3 at all. My Nissan 200Sx was spraying sparks trying to hook the live from the alternator to the main battery and kept putting my amp into protection mode. Uninstall the live and left the ground hooked to the alternator and i was pushing over 14v and would rarely drop below 12v on a 2k draw

Question. On my 06 F150 my engine ground block is on the back of the motor and stock 8g wire ran to the firewall. Would I be able to use that ground from the firewall to the battery or go directly from the starter to the battery?

Double up both grounds if able.

To verify : You grounded most/all grounds to factory locations along with factory wiring/grounds. 2, you have 2 power wires to alternator. 3, you have 4-5 wires on the negative of the battery. ,,,Will I still get a improvement by doing this if I keep the factory alternator?

It's for better electrical current draw across the system and vehicle. Usually people with after market car audio systems running 1,000 watts or more do it.

@@JacobViral2 so if my truck drops voltage at 3,000 or higher rpms because of my 2k scar monoblock amp does this mean it won’t drop lovage anymore if I do “the big 3” because my alternator and battery are brand new and I don’t know what else my car loses battery to other than my power wire to my amp

Hi Jacob! My oem wire from alt to battery goes to a fuse block under hood. When doing the big 3 charge wire do I bypass the oem alt to battery wire a d leave it in place then do my 1/0 from alt to battery? Or do I run my 1/0 like the factory did to the oem fuse block?

Stock Fuse block I never needed to touch, just add wires to the critical.

@HIGHROLLAZAUTOCLUB Год назад

Instead of running 2 0 gauge, power and ground each from the alternator to the battery. Can you just run 1 double 0 gauge power and ground each from alternator to battery? Also in these 2 setups what size fuses will you use?

@JacobViral2 Год назад

correct that will work. Usually 250-300 amp fuses if 2 runs I always did.

@lukegale717 2 года назад

What if there's a fuse and relay Box in between the alternated charging cable and the battery positive? Should I bypass the box or just upgrade both wires?

@hakanwall8941 2 года назад

Seen several videos now on this big 3, and all say that they kept the stock cable, but not why, why keep the stock cable I assume a 0 gauge cable can handle the same job as a 8 gauge.

Safety and doubling up runs is better then removing to upgrade size only. Also never know if you will later remove or have problems with stock being replaced so just don’t mess with.

Hey Jacob, how do you determine what enclosure to go with (port,4thO,6thO) on any given vehicle?

@JacobViral2 4 года назад

Depends on space, bandwidth goals, and preference really.

@no3mun0z 4 года назад

6th is loudest followed by 4th, then port. But 6th is also the biggest box followed by 4th and port. So you pick based on how much room is in your car. Also 4th and 6th can't play all the frequencies so that's a small sacrifice

@biggklown7644 2 года назад

What about SPL boxes? Big port area tuned to the middle of the range you want. If your range is from say 28hrz to 35hrz, I'd tune the box for 30 to 32hrz. And I love the 16in/sq for every cubic foot of box is an awesome sound. I love my box I built using sub box pro app on my phone. With a 1000watt class a/b amp pushing my Skar EVL15 D2, I can make the doors bounce, and the rough flexes...👍👍👍
