i just put 2 infinity 12 inch subs in my 88 gxl there on top of were the bins used to be firing back but if i turn the radio half way up the glass bounces im into loud steros and was wondering what people have done with there hatch glass to keep it from bouncing ....im afriad im going to break it .... it really bounces that bad it looks like a sub with about 1 inch exposure ......thanx guys

 

Well..... You could find a way to move the hatch locks down- do it locks it tight against the frame-

Or you could replace you probably worn rubber seal with a new one.

I have 2 10's pushing probably alot more then those 12's- and I havent had a problem.

 

Damn
