Where did you guys run it through the firewall?

It doesn't look like there's much room. Any advice?

 

My advice to you is to tell us what kind of Acura you have and the year..

 

lol i guess that would be a good idea.

It's a 2002 tl type-s. It's a 0 gauge wire (pretty big). I wanted to see if there are any spots that are left open (no driling needed) and if not where you guys suggest I drill.

 

There is one unused groment in the firewall, but you maynot fit that wire though it. 0 guage wire is overkill anyway since you are limited by the smallest wire in the circuit. Any wire larger than 4g is just useless

 

There are plenty of amps out there that require a 0g wire just not to void the warrenty. You always want to ensure the amp has proper power otherwise they're not gonna be so happy and in working condition. Also, how would I power 2500 watts properly with a 4g wire?

2 x JL 1000/1
2 x JL 300/2

Also i'm not even quite sure what you mean by you're limited by the smallest wire in the circuit? Have you ever seen what happens to an amp when you don't give it enough power or a wire that can't give it enough power?

On the other side, you can't give an amp too much power.

Look at the JL 1000/1 for example. It requires a minimum of a 4g power input but only outputs 8g to the woofer.

 

I beleive there's a open grommet above the gas pedal or brake pedal.. Somewhere in that area but as spdy said it may be too small for the 0 gauge.

 

0 ga will definately fit, with very little clearence..

 

I don't want to get into a pissing contest with you, but I am an electriical engineer so im not just posting for the fun of it. The onlyway your gonna benifit from that 0g wire is if you run a seperate power and ground straight from the battery, which nobody does. Most likely you will run your power wire and ground the amp near the amp. Well guess what, how is that ground getting back to the battery.......Through the 4g wire that grounds the battery to the car. Havent you ever hear the phrase "your system is only as good as the weakest component", it applies to wiring as well. Your factory 4g battery cable is your weakest link.

Oh I think you mean you can't give the amp enough current You can indeed supply too much voltage to the input and then bad things will happen.

 

Oh I see what you meant now. Of course the battery also gets a 0g ground (i'm not that big of a noob, i'm just not confortable with cutting cars and making holes but i have good knowledge of car audio and electric components). I put in a 200 amp alternator and I got a new battery. I'm auctually doing a dual 0g ground for the battery (got a nice battery block, so why not). And yes of course too much voltage will damange the amp, most only handle 6V inputs, what I meant to say was current.

 

spydey, do you mean in laymans terms, that he needs to do the big 3 upgrade?

 

This is why you UPGRADE the battery ground cable to 0ga. You don't even have to remove the OEM battery to chassis ground wire, you just add it on top. Electricity will follow the path of least resistance, in this case, the 0ga ground wire. Can you quote me on this spdy0001?

 

Actually most amps have a 6V max input on the RCA, or signal side, but its usually 11-14.5V for the power.

big 3 upgrade Upgrading all wiring including grounds will do the job if thats what you mean

You are correct sir Electricity acts like water and will flow throught the least resistance. Since he is upgrading his battery also there is really no need to keep the factory wiring though. I would just go to the 0g wire.

 

Not to mention the factory one doesn't look that good. Having a single or dual 0g to ground (dual is overkill but can look nice) just looks a lot cleaner and better.

 

okay...i am having the same problem. i am following the DIY guide and found the exisiting hold in the firewall, but i can't seem to get through it. i've tried everything from jabbing it with a screwdriver. there is a thick rubber feeling thing behind the foam that i can't get through. any help would be appreciated. thanks.

 

I'm gonna do it one way or another this Saturday and I'll try to make a DIY for it.
