I purchesed some subs and it is simple the spoiler rattles like crazy. It makes it sound like one of those beater cars with more money in the sound systme then the car. Is there anyway to fix this?

 

Is the spoiler bolted down tight??

 

Check the bolts on the spoiler like LoveMyTSX said, and then if needed, get some Dynomat (or other sound deadening material) and place it in your trunk, and maybe double it up on the lid portion of your trunk. It won't be heard nearly as loud outside your car if you use it, but it may stop your vibrating spoiler!

 

^ my thoughts exactly

 

ok thanks very much i will try that
