good audio setup for expansion?
i've looked into several ideas for an audio setup and for now i just want 1 sub, but be able to put in a second with re-wiring a new amp. so if i were to install this:
12" Rockford Fosgate Punch 2
@ 50-200w RMS & 400w peak
What amp should i get for this so i don't have to buy another when i get a second sub?
also, i have the stock head unit with single cd player. do i need an aftermarket one to wire it all in?
