i had 1 10" rockford hooked up to a p.o.s amp, and my interior lighting flickered. now that i have two 15" kickers with a 2000w amp, i need another battery. should i just buy a bigger/better battery for the whole car or just a seperate one for the subs. and where would ya put it? and also, i dont want no optima yellow top shit, just something to power my subs.
