Just installed two JL Audio 10W3's in my car, hooked up to a JL Audio 500/1 slash series amp. The trunk, trunklid, and rear deck lid vibrate and rattle everywhere now. Already tried dynamatting the trunklid but doesn't seem to do much. Can anyone else suggest anything? Thanks!

 

i dont know...did you try dynamat the entire trunk or just the trunk lid? i dont know if thatll make a difference

but what kind of enclosure did you install the w3s?

 

i just did the trunk lid cuz thats all that shakes but still no luck. the enclosure is a sealed box, if that helps...

 

I dynamatted my trunk lid when I installed a 10" Alpasonik 800 in a vented box and it solved the lid problem 95%. When I did the trunk lid I removed the licence plate cover (where the reverse light and license plate are... the grey portion) and installed some dynamat and edead teklite behind it and also did the same to the actual license plate. I then adjusted the trunk lock hinge so it put tension on the lock because alot of the vibrating relocated there after the dynamatting. I just get a little vibrating at the very end of the truck lid near the rear windshield because I couldn't get dynamat material to that area.
Another source of vibration is the third brake light cover... I used teklite there also...

Good luck....

PS: I now have to use a jack to open my trunk...lol

 

when u dynamat, it usually gets rid of the problem. im not sure exactly what it is but it could be any number of things. just dynamat your entire car. =)

 

Could you expand on this a little more on what you did because I have the exact same problem with rattling from there.
