I acutally opened my whole rear deck, but couldn't find the problem. I had taken the stock sub out, when I installed my Kicker L7, but today put it back in, thinking it would help, but it's still there. I tighten all the bolts from the trunk, to the deck. I'm sitting on 18"s, and roads are good to excellent ( general area ). Any idea? Thanks for the help!

 

Can it be your suspension?

 

I was thinking that bro, but the noise only comes when the road is uneven, small bumps, but even sometimes when the road is just clear. It's just annoying. Hopefully when I change the springs and shocks, it will help!, Could be my shocks? Hmmm

 

Mine was rattling when id hit bumps or real low bass would hit, and i took some half inch black foam and shoved it between the deck and the back window with a butter knife...you cant see it at all and it took the rattle right away...sounds kinda ghetto, but its the only thing that worked for me

 

I have the same problem... sounds like a piece of plastic on plastic rattle right? Never found it and still looking.

Big bumps don't make the noise, but road vibrations as you say to create the problem.

 

dam u got L7 , lolz i got my L5 for like 100 bucks brand new lolz, planin to sell it lol

 

Yea bro, one 12" L7 740 RMS, soon to have it in a ported box, HITS! I paid 150 with the kicker grill. Nice equipment.

 

I need to do this..

 

I finally found it and it is as you said about the deck lid. If you push down on your trunk you will notice it go down a little and letting go it will come back up again. Kind of like from the tension from trunk torsion springs. I just installed the new torsion spring bars to support the spoiler weight so the sounds are worse now.

Where did you place the foam between window and deck lid? I was looking at placing it at the end near the rear lights right under the 2 rubber spacers beneath the deck lid.
