I just installed one 10" Pioneer W254C into a sealed q-logic box (w/ Premier X220 amp) and it doesn't sound all that great. However, when I open the trunk the bass is awesome. I can close the trunk, sit in the car and listen and then press the trunk button and all of a sudden it comes to life when the trunk is open. The mirrors actually vibrate when the trunk is open...
What's my problem?
