i have an 04 tsx upgraded the speakers in all 4 doors to some infinity's but decided to disconnect the 2 6x9's rather then upgrade those also because i put 2 12's in the trunk. sounds great til i crank it up, the vibration coming from the back panel is very annoying! any suggestions?

 

Turn down the volume, you aren't any cooler with the volume so loud the neighbors a mile away can hear you...

 

Jcast,

I have the same issue and it drives me crazy!! From what I have read its just the crappy rear deck design. I removed my junk 6x9s to allow more sound into the cabin from the sub. (10" MTX in custom fglass pocket enclosure)

Solution: Dynamat the living crap out of it!! I have tried dynamating the underside (in truck) with no luck since I have no idea how to remove interior rear deck cover.

If it works lemme know...if you remove the deck yourself write some pointers so I can see if its something I can tackle!!

~C~

 

I kinda have the same issue, but I dont have any systems pumping loud musics... its my exhaust making the trunk or rear speaker area vibrates.... any fix?
