i need a capacitor for a 500 watt system. my system is suckin bad! it dims everything. guess thats what 2 15's will do. well if you have one or know where to get them cheap let me know!

 

ALMOST all capcitors are the same (specs). It is just a matter of personal preference. What type of amp?

 

i have 2 15" dei pro's. what kind do i need
?

 

I would look for a 1.5 farad. That would be more than enough. I use Rockford Fosgate for mine (3 1 farad caps with a link). You could get some form Lightning Audio. Smae thing,different name, lower price.
