Got my Alpine Type S 12" woofer and Alpine amp put in Friday!
So putting the box in was pretty hard, no lie, the box itself wouldn't fit and we had to find a way to get it in. It sounds great, only problem, that top deck lid vibrates like crazy!!! everytime the tight bass hits, you hear an annoying rattle, nice low bass you don't hear it. How can i solve it? I'm trying to find alternate ways in which i don't have to spend money on dynamat!

I'll get some pics of my amp and sub soon!

 

I've got the same problem with my sub, that damm spoiler is always making a rattle, but its not so bad from the inside, I dont hear it. Its only when im outside the car.

Two things i noticed rattle:
1) the child support plastic peices, open those up to stop from flapping
2) a couple plastic pop in screws under the deck lid, push up the deck and push those down, or you could try doing it from inside the trunk

hmmm, where are these located at? i don't hear anything outside, it's the inside taht drives me crazy! cuz i wanna crank it up, but i don't wanna hear brrrr brr brrrr vibration lol.

 

This is a bad picture but its all I have, inside, in the middle of the speakers is some stuff, theres a couple things under there you could secure, such as the plastic wires for the rear seat disconnects, check around and tape some stuff down

 

hmm, thanks man! have you noticed any other things that rattle? and what have you, yourself taped down?

 

dynomat the deck.

 

theres a connection harness on the right side of the deck for the read lights, maybe thats rattiling a bit?
