Hello, i just installed ponineer (sp?) speakers in my 86 trans am. The only problem is thatt when the bass kicks in, it vibrates the area which the 6x9 speakers are in. Are there any ideas as to how to stop this annyoing thing?
Dynamat or roadkill or any of the other sound deadening stuff available. Lay a sheet of that stuff on the sheetmetal and the viabration should go away. I'm sure many things have been come up with other than dynamat since the mid '90's when I was messin with this stuff so wait for KristKustoms, he should/might know.
Dynamat is good stuff, we have used it in alot of cars we've done. It is also a good heat insulator. Lately we have been using a sound deadener called FatMat. FatMat is basically the exact same thing as Dynamat Extreme, but it is alot cheaper than Dynamat. FatMat is 1/5 the price of Dynamat.

I just roll up an old rag and hide it behind the molding that is rattling. My daily driver has several hidden rags. It was brand new when I put the MTX 10s in it and it rattled like a 20 year old ranch truck.
you might check to insure the speaker are in phase. if you installed them using the factory wire then you could have them out of phase causing them to pull inward too deep make unnessory rattling.
if you ran new wire or have an amp hooked to them still insure that the phase is correct.
if you have an amp hooked up check to see if the gain control is adjusted correctly and not turned all the way up.You never want to run the gain at max.
the proper way to adjust the gain of an amp is to first turn the gain all the way down and the head unit all the way up then slowly turn the gain until you hear distortion and back off about 1/16th of a turn.
bass will caause rattles in loose or misinstall panels.
if the panels are causing the rattle then dead beat or anyother sound deading nat will not cure the problem. you must replace the fasteners and clip the hold the panel in place.
if you let me know more about the type of install you did I will be more then happy to help you work through it.
