Black Beast Posted January 26, 2008 Report Share Posted January 26, 2008 What have you guys used to stop the rattleing behind the back seat? I only have one twelve back there but it drives me crazy. Quote Link to comment Share on other sites More sharing options...

misterp Posted January 27, 2008 Report Share Posted January 27, 2008 It's common for the trim running under the bottom-edge of the back window to hum, that needs to be removed or padded or etc. And yes dynamat the entire rear wall of the cab, it will make a huge difference. Second place to dynamat is the roof, take down the headliner (not an easy job) and dynamat the roof as well as fiberglass in a couple of support struts and that will eliminate roof flex. Doing the roof and back wall will get 80% of the job done, sound absorption wise and lower interior cab heat 10-15 degrees. Mr. P. Quote Link to comment Share on other sites More sharing options...

Braxton Posted March 5, 2008 Report Share Posted March 5, 2008 this is a little late...and a very simplistic answer... but when i had problems with my subs rattling the area around the back seat i just got underneath my truck and bent my heat shield out a little. have not had any problems with it since! a cheaper solution than dyno Quote Link to comment Share on other sites More sharing options...
