What is the best sub/amp combo for <500? I know that this is a pretty broad spectrum, but i know absolutely zero about car audio. Basically, what I am looking for is a halfway decent setup for an affordable price. I would like 2 12's in an enclosure with 1 amp powering them if at all possible. I would like to reiterate my lack of car audio so you will have to bear with me. I went to best buy the other day and all they had were some rf punch's that weren't too impressive, and some 450w pioneer's that i liked. I have yet to make a trip to the specialty shops, but before i do i'd like to get some feedback. thanks.
