I have a Wal * Mart / Curcuit City system in my van... 2 Pioneer 10" "I like the hard hit" of the 10's for rock and roll and the 10's hit hard like a firework with 400 watts behind them... I got 4 6x9's and 2 6" rounds and 4 tweeters... I have Jensen amps,don't knock em till you try em... I have an old Alpine head unit,the best clarity in the tweets and mid range IMO...
