thanks bam bam for the insight. i try not to blow it up 24/7 because that will definately hurt me in the long run but sometimes i just have to for a couple songs...as for the rattling, i have come to a conclusion that after hitting 148dbs so far without maxing out yet, there is positively no solution to stop the rattle COMPLETELY. its impossible. i have dynamated every centimeter and still the wiper, back window, sides, taillights, exhaust, EVERYTHING rattles. i guess its just unstoppable. if anyone has something to help i would like to hear about it. but thanks for the replies.
