Official CarAudio.com Big 3 Thread

My stock wiring is in decent shape, but I would much rather replace everthing 1/0 gauge wire. Should I add or does it really matter that much? I feel better having all connections & wiring fresh than adding & still having the old wiring there.

I have a little bit of a differant question, I have a 160 amp alt and 2 IA 20.1 amps. i already have the big 3 upgraded to 1/0 but i'm having troubles getting my amps to burp at .25 strapped. I have 2 runs of 2/0 going to the back and 2 2/0 grounds grounded to the chassie but am thinking of upgrading to 4 runs and upgrading the big 3 using 4 1/0 wires for each of the 3. Should this help my amps get a burp off. Would i be better off running grounds from my batterys negative to my amps instead of grounding the amps to the chassie?

 
Will I void any warrenties by doing this? I've got a 03 murano that even with a yellow top and cap dims, so I am thinking of doing this but obviously don't want to void anything.
This won't void anything if you simply add to the wiring vs. removing it.

You should get rid of the capacitor as well.

You're way above the level that the big three can help you at bud. You need to look into some beefier batteries.

Add to the old. Better to have more paths for power to run down. I replaced mine because the wiring was litterally falling off from corrosion.

Can someone take a pic or highlight the lil piece of plastic that you have to break off and/or put on when connecting the 0/1 wire to the alt? Because this is the ONLY part I'm not understanding...
You may not have to break anything off depending on your application. Find the bolt coming out of your alt that has the positive lead connecting it to the battery. If you can fit another ring terminal on it without breaking anything, don't worry about it.

 
I have a 1998 Lumina wit a 3.1L. Im plannin on doin the big 3 soon. I have found where all the wires run around in the engine. The only one I am havin problems wit is there is no wire that goes directly from the batter to the alternator. I cant even follow it where it goes through fuse boxes. The one wire that comes off the alternator goes into some fat loom and i think it goes to a fuse box thats on the opposite side in the engine compartment of the battery. I am going to use 4 guage i think because i dont want to spend to much and its bigger than stock.

Anyone ever done this on a 3.1L? or if you know please help.

And is that the engine block to ground right next to the starter?

 
i have a 91 integra and am getting a new system.

a T8002 to run 2 jl w6v2's and i was wondering if i would need to do this or not.

my last system was 2 RF P3's on a p8002 and was getting some cutting out and i could never figure out what it was. also anyone with a japanese car with a cramped engine space let me know how hard it was to do the big 3

 
Went from 4gauge to 0gauge: ALT to BATT today and there IS a difference! I will have to get my grounds in 0 gauge soon. //content.invisioncic.com/y282845/emoticons/inlove.gif.6846f78f06b405429ef3a00129788a2a.gif

It took forever tho [3 hrs] because lack of proper tools [i had to implement severall] and just Honda has a tiny engine compartment. Lookin for a place to put the fuse was a hassle. then as I was setting everything up I thought of a better way to run the wire //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif:D:D

 
*sigh*
I miss my accord. That car was kind to me.

I added on the "BIG 3" using a 4 ga cable and still notice dimmage. Would a 1/0 ga cable make a difference? I have an OEM 105 amp alternator. Looking into getting an 180 amp alternator if an Optima Yellow Top battery does not work. I have a strong feeling that it will not work, I guess that is the price I have to pay.
The list of my audio equip. is in my signiture.

Okay I need some feed back because I have sum parts and a lot of money... Im am about to redo my whole system I will be running (2) Earthquake 5000 watt amps, (2) Concept Amps for my highs, crossover, maxxbass, and 300 watt sony amp for my tweeters, all this will be in my 2000 Dodge Stratus I already have two batteries one up under the hood and one in the trunk... I need to kno everything I need to do to keep my system at 14.7 or more volts like I said dont worry about money just tell me the idea's and what I need

 
okay I can do many runs of 0 gauge but ion know where I could but another alternator I only have room for one and that's the one up under the hood and I know I have to get a high output alternator what else do I need and I know I might need 3 batteries the one up under the hood plus two in the trunk... but what exactly is the big 3

Just wanted to say I love this thread, even though the Big 3 still hasn't helped me...

I have an '89 Acura Legend and I'm trying to run my meager system (200W MTX amp pushing one 10" sub) but my amp has been cutting out/turning off. The car has a 70A alternator, and the battery is good. I didn't think anything was wrong with the alternator, seeing as I just got it replaced in May of this year after the last one died after 5+ years of use.

So, I considered getting a capacitor, but after coming to this site I found that it might not be the best thing to do, and decided to do the Big 3. Cost me about $50-$60 getting the necessary tools described in this thread, and I used 1/0 gauge wire. Hooked everything up, and still had problems with my amp cutting off.

I go to Autozone and Advance Auto and get my battery/alternator checked, and everything seems good, except for the fact that my alternator seems to be outputting only 4.8 - 10A. Holy crap, I don't see how my car is even running... or charging my battery. I'm going to go back to the place that put in the alternator, hopefully they will do something about it.

Anyway, just thought I would share my story. This site (and especially this thread) rocks. Lots of helpful ppl here.

I'm open to any suggestions.
