So I just put some pioneer 10's in my sail panels and now the gas cap rattles like crazy.Pretty lame I thought there would be more problems with other parts of the car being noisy but noooo had to be the stupid gas cap.So my question is does anyone know of a good locking gas cap that stays on tight?Thanks.

 

Well at least you can thump your way down the raod if you run out of gas!!

We have whatever * AutoZone * sells on 1 of our other cars. Thing is with this one-- some times you turn the key left to unlock it, some times to the right

 

Try applying some sound deadener (ie Dynamat Extreme) behind the subs. It will reduce the vibration.

Simple fix.

 

I have peel n seal in it but I only did one layer,was thinking about doing another.Its just really annoying.I was also thinking about Spray foaming it a little more and re cutting it and fiber glassing to make it more rigid.Dont know if that would help though.

 

Peel N seel will help only a little bit. You're best bet if you are going to take the time to do it is to do it right. I either recommend Dynamat Extreme or Second Skin Damplifier Pro. Preferably the damplifier pro. But you need to do that whole area there well.. I have Rockford Power series 6x9s in my sail panels with about 80 watts going to each and a full layer of second skin pro, and it still rattles a little, i'm going to go through and do another layer.
