Replaced speakers. Bass rattles plastic panels.

[Edveen]

There is of course a difference in sound quality. The mids are clear and highs are sharp but not to bright. The lows have the potential to thump BUT unfortunately, my Ford Taurus GL station wagon shakes and rattles creating this annoying plastic rumbling sound. The only way it goes away is by holding down the plastic panels. All the screws are in and tight but unfortunately, these cars werent meant to handle these kind of things. What can be done to cure this problem other than applying Dynamat? (I plan on adding dynamat)
I fear that dynamat itself wont stop the problem.

You can reinforce the panels by applying fiberglass to the back on them. It will work, but its time consuming. You can also run a bead of silicon around the edges of all the panels where they meet the doors and sides of the car. You can also try spraying bedliner on the back sides of all the panels. Basically do anything you can to make the panels more ridged, but also so they don't rub against the metal of the body.

the silicone idea sounds good. What should I get from the hardware store in order to do this? any special kind of silcone product I should get? Thanks for the help

Just regular clear silicon tube and a chaulk gun is all you'll need.

how did you do your rear speaker? i had to shim out the plastic panel with some washers.

 

[Edveen]

I simply screwed back in the rear panels with the screws. I think I should put some sort of rubber washer to help the panels stabilize a bit just like you did. I tell you what though, those rear speakers were are a b**** to put on.

You can always try to secure stuff with zip ties underneath where it's out of sight.

yea they are. if my polks were not componets i would have had to cut the panel to use the grills.
