battery question....

[cjj2d 10+ year member]

Right now my car is ran with 2ga wiring from the battery to the amps in the back. In a couple of weeks I am really vamping up my install and am either going to add a yellow Top or just replace my current with a yellow top.

My question is could I use the 2ga wiring that is currently installed to connect a yellow top in the trunk then run 1/0 off the yellow top for everything else? also I will be doing the big three with 1/0 just wasn't sure if the 2ga wiring was too small and insufficient for my project.

Without knowing what current draw you'll be pushing, i can't ay if the 2ga is 'too small' for your project. But if you're running 2ga to the trunk, don't run anything thicker from that to your amps or distro blocks -- run the same, or thinner wire. In my car, i have 4ga run to the battery from the front, then 4ga from the battery to my distribution blocks...then 8ga for each amp respectively (not pushing the kind of power you are!)

the amps I will be running are in my sig with the midbass amp to be installed soon.

looks like I will be ripping out the 2 ga wire and replacing with 1/0, I just didn't want to have to go through that headache but oh well.

You would need to add a run of 2 guage, one for positive terminal and one for the negative, but it should be fine.

Oh -- yep. 0ga the whole way man //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Suckage maximus. I went with 4ga to future-proof myself a bit even though i could've run 6 or even 8ga and gotten away with it. I wish i had run 0ga myself now //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

What vehicle is it that a couple runs of 1/0 is a pain in the ***? Mine went in like a breeze.

its an altima, and the only pain in the *** part of it is removing the 2ga wire and running the 1/0 through the firewall etc.... after that its all pretty simple.

Use the 2ga to pull the 0ga through. Ducktape the ****er together and just pull it through. Piece of cake when you've got a wire already run to run another...just don't think that yanking harder and harder will fix any snags you hit along the way -- if you're yanking and you hit a dead stop, figure out whereabouts it is, pop just that panel off and get it un-hitched.

Yeah I am going to try something like that. then probably just drop the optima yellow top in the trunk.

Make sure you get it somewhere it won't fall against the side of the car just in case. I velcro'ed the bottom of mine so it wouldn't slide when i take corners at 120...
