rockford fosgate all the way. dont get any of the prime stuff though go with the punch series its good priced and real good shit. ive got who p3 10s with a punch 500 amp and its amazing. wouldnt trade it for anything im planing on adding to them in the future but for what i spent on them i couldnt ask for anything better. o and a good deck will help too ive got a kenwood woth 4volt outputs anything with 4 volt outputs will sound better than the average 2.5 volt output
