Hey all

just upgraded all 4 door speakers in my 14' screw to the Infinity Primus PR86020cf.

the install was easy and the speakers sound great ...still breaking them in

however i noticed the rattle in doors is really noticeable.
i want to install some sort of dynamat or other sound/vibration deadening.

anyone have pics of them installing such products?
im interested to see how you applied it...where..and what product you bought.

your help is appreciated!!

nothing?
no one has any info or pictures on where they installed dynamat in their front door panels?

I didn't use it on my speaker install this time around, but in the past, I've used dynomat in between the speaker and door panel. You'll have to unscrew the speakers from the door and wherever the speaker touches the metal, line that area with the dynomat, even where the speaker screws into place. You want the dynomat eating the vibration.


Also, check the harness. If you spliced it and left it, or used a harness and there is slack, ordinary driving will make it tap the metal door panel causing an aggravating rattle. I duct taped mine inside the door panel cavity so it couldn't move. Helped tremendously for me.

I should have some more pics this weekend but I'm in that process right now. I have adapters to go to 6.5 rounds with fatmat on top with ccf on bottom. The speaker came with a gasket for mounting to the front face of the adapter.



I'm also adding mlv, ccf, and fat at to each door but don't have pics of that yet.

Please don't use fatmat in a $40,000 truck.

Can you elaborate?

Never mind that's what I get for not researching. At least I'm not too far in on my install to change it up.
