i just put a sub in my 98 civic and the rear deck rattles like crazy. i have dampened the trunk, but i dont know if i should dampen underneath the deck-salesguy told me u cant prevent plastic from rattling. Any suggestions?

 

get some of that stuff they put on the back of cabinets to prevent it from slaming hella hard, you can get it at home deopt, and put it on the bottom of it. Its like this tape looking stuff and its about 1/8 in thick foam pad with one sticky side.... or just take it out all together.

 

Crawl in your trunk. Look at the bottom of the deck - see the big holes? Shove socks in there, to push the plastic cover up.
Done Free Works great

 

i have the same problem but the rattling sounds like it is coming from my 60/40 split seat. haven't had the time to sit down and try and track the sound but that might be another place to look.

 

when i bought the car i noticed the guy had put socks in those holes. i took them out not knowing what they were doing. but i dont understand what it does? u said it pushes the plastic cover up. what do u mean? thanks everyone.

 

i had the same problem, and fixed it with a t shirt i had that came vaccuum wrapped into this little ball, i just wedged it between the glass and deck lid and it completely cured the rattle

you might also be able to use a racquetball or something similar that will stay in place

you should have asked this in the Audio Forums, you would have gotten a better answer

 

where on the deck lid did u put it to stop the entire deck from rattling?

 

Just shove a sock in there again.
Its not very hard to figure out what it does...

 

i shuved two big *** socks in there. it helped but it still rattles.

 

It needs to be enough to press the rear deck up and in several spots

 

how many spots can u put them with only 2 holes?
