Vibrations from speakers in the back

[erlendch]

I mounted two 6x9 Kickers speakers in the back of my charger. As shown on picture. It rattles A LOT! When bass kicks in everything vibrates and makes a lot of noise. Any advice? It also mounted speaker in dash, two 4 inch similar to what I've seem others here have done. Also rattles, but not as much as they produce less bass. Advice on what to do in front to would be very welcome! Thanks guys!

Add some Dynamat or equivalent sound deadner.  It'll quiet it down and it won't vibrate as much.

If you added aftermarket speakers to the original head unit in the car the problem may be the head unit.   Try turning down the bass or put a filter in the speaker output circuits.   The old head units didn't have much in the way of fidelity so you may now be hearing what the head unit is putting out for the first time.   Alternately if you got all the same brand speakers, the speakers are the problem.

Here's a easy test.  Dismount the rear speakers from the package tray and run them while lying on a piece of carpet in the trunk.  Still noise..speaker or head unit,; no noise..it's a mounting problem.

Could be the cardboard trunk divider rattling.  It can be the trunk lid torsion bars rattling.  From factoy there was a 6" split hose placed on one rod between the two to eliminate rattling.  Also, check your jack and spare tire to see if they are secured. Do you have the jute underneath the rear package tray?  If not that can rattle.
