I have a 2001 pontiac sunfire with two audiobahn 4ohm 12's that handle 600 watts a peace in a MDF box with a 800watt boss amp that is bridged powering the subs. I have INTERFIRE 4x6's and lanzar tweets in the front and PIONEER PREMIER 6x9's in the back. the tweets,6x9's and 4x6's are all amped up with a 200 watt sony explode amp. I have two sound activated purple neons in my car that flash with the bass. One is in the front underneith the deck and the other is in the rear window. The trunk of my car is done with extreme dynamat to keep the trunk from raddling.
