i am wondering what to do i have vibrations from the speakers in the back deck lid as my bass has and loosens the screws that hold them down. i was gonna use bolts and nuts on the bottom to hold them down but it is impossible to get the bolts and nuts in place due to the construction of the frame under the deck lid. would fiber glass help holding them speakers in place would it crack due to bass pressure as it is now the beck lid bouces about an inch when bass hits. would i have to install a post to reduce the risk of cracks.

your knowledge will help me greatly
thanks justin

Try using locktite on the screws and use Dyno mat to reduce vibrations...btw fiberglass wont do anything....do u have your subs facing up pounding towards the deck lid?..if so face it towards the rear of car

my 6x9's are in the deck lid and my subs are pointing backwards i said fiber glass as it would make the decklid strong instead of the cardboard or w.e what it is covered in fabric you cant use lock tight on this.

ah I see..I would then cutout wood rings to go underneath the deck lid thus you are screwing through the decklid then into the wood...this will allow for alot thicker base for the screws to drive into.

that was a great suggestion lmao simple and i never thought about it thanks allot
