i want to add a second battery so i can turn off my car and play music without the worry of not being able to start the car after im done playing. plus my car is a work in progress, i plan on making it into a show car in the future. so im slowly doing things wit it. i want to be able to power my whole system: deck, 2(4x6), 760W amp powering up to2(500wsubs), 2(6x9), 600W amp powering 4 (6x9), and 2 sets of neons. i know that a cap will help but i want to be able to go to some car shows and be able to play my system and not having to worry bout it running down the battery. my system is all pioneer if that means nething.

 

A cap won't do crap bro.

Look for something deep cycle, around 750-800amps.

 

yeah thats what i got a i think 700 amp battery but i want something just to run my system on so that i have no worries of not being able to start my car due to dead battery

 

i really need to know how to wire this up and where to put my fuses and things
