one simple question, ported or sealed. i got bored one day and decided to REALLY blast my system after getting out of my friend's car. he's running two 12" pioneer subs in a ported box. his system sounds like crap, but i really like the loudness of his music (well im picturing it with my clarity hehe). well anyway im listening to music and i notice that my bass is mostly in the back (no bass in the front whatsoever) and I dont like the fact that i cant really feel the punch of my sub. i have 4 3way speakers that are pioneer pushed by a four channel alpine amp, and a 500/1 mono amp and a single 10w7. ive heard single w7s in other cars, and it sounded amazing! what do you guys think i should do?
