Hey guys, I have the alpine 9853 headunit with the stock subs still working. My problem is the damn buzzing noise coming from the rear deck everytime the subs thumbs. The buzzing is coming from the rear deck hitting the window. Is there away to stop that? I notice that if I stuff a piece of paper there, the buzzing will stop because it's not hitting the window. But I had to take that piece of paper out because it looks to ghetto. Anyone have any suggestions to stop the buzzing?

 

take te rear deck and try to readjust it. Maybe use some foam rape between them?

 

i had this problem in my a4. what i did was take some foam or rags i had. balled them up and shoved them from the trunk under the rear deck. i don't know for sure if you can do this with the tl's but im pretty sure if you take the brake light housing off you could tuck it around where the sub goes.

 

Get some foam weather stripping from a hardware store and line the edges of the rear deck with it. Also, put some around the rear brake light.

 

I have to do the same thing. that noise drives me wild....

 

This is what I did with mine






Buy a gallon of liquid sound deadener and apply it to both rear deck panels and to the metal underneath. About 3 to 4 layers to the panels and 2 layers to the metal or you could just use some matt for the metal. If you finger flick those panels they resonate like a pitchfork, but sound deadening them will take care of that.

 

good job..
