Bought a pionner cd player w/ hd raido reciver and aux input at best buy. I also replaced my stock speakers w/ 4 6.5 inch pioneer 3 ways. Now I can hook my iphone sounds great. Now im hoping for some advise on subs and amping the entire system. Im open to ideas. Anybody??

 

what's the budget? where are you shopping? what are your expectations?

there are hundreds of options, by answering those three questions you can really narrow down the list of possibilities.

try to get some sound deadening into the budget. sounds like you'll want a 4 channel amp for the speakers and a monoblock for the sub(s).

if you're shopping at Best Buy, Alpine has some decent amps that are affordable, as well as the Type-R subs.
