heys guys, so i just finished installing 36 sq feet of deadner in my car and it helped out tremendously. the anoying rattles i heard before are gone and even the ones on the outside for the most part. after installing it though it seems my subs do not hit as hard as they had before and i was wondering if anyone has had the same results as i did. i have a 2003 celica and i installed the deadner on the inside and outer door skins and did this all the way back into the trunk
