I just finished putting my subs in the trunk. Two 12in MTX in a bandpass box. I turned it on and it sounded great. Pounded hard and sounded clear. The problem is when i stepped outta the car i noticed a horrible rattle. I jacked the car up and couldnt see anything moving to much. checked the trunk and still didnt find anything rattling around. if anyone else has had this problem and fixed it please let me know what could be rattling. it sounds like i got a muffle dragging when im standing still. any suggestions would be greatly appreciated. Thanks.

Ive gotten the heat shield on the muffler itself to rattle. Do you have anything sound deadened?

bumper against the body
muffler heat shield
rear deck against window
3rd brake light assembly
spoiler
tail lights
door trim

some things to check. Check by pushing against them to see if the rattling sound stops. My guess is rear bumper for muffer heat shield.

Or check under the seat, something might be hinding under there :?

Check your license plate...........Its more common a source for rattle than you would think.

Dutch

Might want to check the sunroof that metal thingy in there could be doing it too

Metal thingy in the sunroof? You mean the motor?

I don't know what it is, it looks like a shim, goes the width of the sunroof opening and is about 2 inches wide

thanks guys ill check all this stuff and post back. No sound deadening. would that help?

Finally a member of the club withing driving distance of me!!!!! Sound deadening will help dramatically and will improve the over all sound of your system. If you want, I can meet you somewhere and have a listen for you. I am so excited!
