Subwoofer GURU needed!

[King RT10]

My 99 RT10 sub upgrade did not make much of a difference, because of the glove box.
Everything in it and the door itself rattles..

 

[AJT]

The only way to get bass in an RT without massive fiberglasss input is to put a box on the pass floor.

The last post by me has all the measurements & pics.
