OK, I don't know if this question will he dumb because I don't know alot about it but I want to buy some R.F. stuff for my car but I don't know if the stuff I think I want will even work. I know I want two 10 inch subs like P1 in the punch category but what amp could power those and the existing stock stereo in the car? There is a stock amp in it but im pretty sure it won't power two more ten inch subs but I don't know. Should I get another amp or a whole new one to power everything? I was thinking a p300-2 amp but is that way off for what I want?
