Some would be fine but Damplifier (and similar products) are meant to eliminate/reduce metal panel resonance. So they will not directly eliminate rattles, though they can and will reduce rattles. Your best bet would be to go with some mass loaded vinyl, like Luxury Liner (just using Second Skin products as an example, you could use similar products to LL or LLP), in between the panels to eliminate rattles (in between the rear deck cover and rear deck).I installed a JBL GTO804 following the instructions (which were perfect by the way). My HUGE issue is rattling. What does everyone think the best route would be? I think 10 SQ FT of Second Skin Damplifier on the top should be enough.... I hope.
Any recommendations would be greatly appreciated!
I also have an extra MDF ring 10" OD and 7-1/4" ID if anyone wants it. $8 + shipping.
Edit: Also, be sure to replace any clips you may have broken while removing the panels. I've broken all most all of mine, but I have taken the panels apart more times than a normal person would.
