electrical system draining... ?
when i sit in my car with the battery on and the engine off, my sound system (700watts from 2 amps) is draining my battery so the ignition is weak, and i was rolling up my windows and the driver side died about 85% of the way up so i gotta give it a minute to recharge or something. should i do the big 3 upgrade? or a new battery like an optima yellowtop? or should i do both?i dont have a cap and im running the stock acdelco batt rite now. thanks.

Re: electrical system draining... ?
changing your battery probably wont do anything at all. your having the same problem I am. You have to find out where the draw is comming from and fix it. I have a cap on mine too and it helps with the light flicker and will save your alt in the long run.

ok, i gotta ask cuz i think im getting mixed up on both of yours. when the truck is shut off are you guys running your stereo or are you just parking it and then when you come back to start it the battery is weak or dead?

Really, if you upgrade the big 3, and get a better battery like an optima yellow or blue top, you dont need a cap.

Re: electrical system draining... ?
ya im gonna read up on the big 3 and do i tmyself this weekend. im sure an optima would greatly help since its a much stronger battery but i just saw they're around $130 and im only doing free mods for a while. ive been spending too much money on my truck lol. should i use 0 guage wire?
