just go to caraudio.com then go to the forums and go into the subwoofer sections. Ull see posts on XXX's, d2's and ED a's all over the place. Ull also read tons of other stuff. U might wanna do ur homework on there for a few days and find out whats best for u.

 

i can see what ur talkin about, sometimes when i just turn the key and let the system run for about 3 minutes, the car has difficulty starting up. and it doesnt help much since i have another amp also drawing out another 500 watts. so u advice me to get another alternator? what kind and how much are they? any other ways to solve this problem?

 

200 amp alt
www.mralternator.com i hear has good prices.

Yellow/Red top battery. I think red top is only like 115$ at discount auto parts. Well the one around me anyways

and i know im gonna get flamed for this last suggestion but maybe when ur done with all that, get a cap or 2

 

i c, about those subs though, is it really worth the money? cause the L7 is 189$ on ebay. and these subs nearly double that. i could get 2 L7's for app. the same price as one of those subs, and double the power with the L7's and ive heard nothing but good reviews about em. thats why im so stuck em on. i just think i like kicker.
