I just recently installed a Jensen 500 watt amp,3 mtx thunder 6000 10"s,bridged at 2 ohms in a sealed box. I have the bass at the amp about 1/3 max and my Scion stock head unit at -5 bass(feel). With the volume at 40 I start to hear all kinds of rattle and vibration,coming from the inside, but can't pin point where it's all coming from. I find this very pathetic as I have an even bigger setup in my 92 summit and have no vibrating issues at all,at least not on the inside that I can hear. Any help on isolating these rattles and possible ways of getting rid of them would be greatly appreciated.

 

plastic panels........that's why you should sound den your whole car.

 

A few of trouble spots for me. . . the plastic covers to access the tail lights(only one side), the 3rd brake light, and the fake metal trim on the doors/armrests.

 

I have two gallons of Edead sound deadener and 4 feet of mat just waiting in the garage.. Now only if summer would roll by faster

The plastic door panels can be deadened with liquid deadener with a bit of cleaning and sanding.

 

For some strange reason I think some of the rattle is coming from the windshield...wtf?

 

Keep the sound levels high for long enough and you will no longer notice rattles. Hearing loss will reduce rattles. Mother nature will solve your problem. Unless your are like my mother who even wears her hearing aids when sleeping.

 

Dash, wire harness behind radio, tail light covers, plastic piece in the hatch, rear windshield wipe, roof, passenger side floor baord (no idea). Both front door panels and glovebox.
But I drive it much harder than my wife. She hears the hatch...
No cure like Dynamat (it is adding 50 lbs to the car currently, might need more)

 

not liking this.. about to put my bass in within the next few days..

 

I dont really have much of an issue with rattling... phew!
