In my TCH the JBL Soundsystem is working very well..I really enjoy the 360-bass they've created with these speakers, but when my car rattles it sort-of kills the sound quality. No aftermarket speakers..all Stock. I've noticed some rattling but while listening to organ music today I heard rattling all over. Stepped out of my car and listened to my driver door rattle as well.. Is anyone having the same problems? What have you used to stop the rattling? I know Dynamat is supposed to be good but I've never used it. ..Maybe the not-too sophisticated interior on the TCH is one reason for the rattles. Anyhow - Any input is appreciated. Thanks.
