150-155 dB? What subs, amp, and enclosure do you have? Have you actually metered it or did the guys installing it just say that. I'm guessing the latter. Most people only get loud when they install the system themselves. Anyway, dynamat is a good sound deadener, but other less expensive brands are probably just as good. But I hear you can get dynamat for cheap on Ebay. Anyway, make me eat my words by telling me what you have in your audio system right now.Originally posted by rokyholler
