I have a 12" subwoofer amp combo in a vented box. I was wondering how to improve the output of the subwoofer. I have a 1994 jeep grand cherokee. It rattles quite a bit. and the rear view mirror seems to rattle a lot on deeper bass tones. The sunglass holder in the center of the roof rattles as well. Any ways to minimize or get rid of the rattling? and any ways to improve the bass output? i have a custom alpine deck, i can control the subwoofer volume separately, and what should my treble and bass levels be at? and my fader? And any other tips on how to keep my subwoofer clean and loud? Thank you
