I have a single 10" bridged to a crossfire 140 (70x2) watt amp, the bass is excelent, but there are harsh LOUD rattles coming from the trunk at certain frequencies. Its not the license plate (screwed down tight, and i put foam behind it to keep it from hitting the back plate), and it seems to be coming from the portion of the trunk closer to the back seat. What usually cuases the most rattle in that area? whats the best way to isolate and eliminate the rattle? Any thing is better than nothing so post away..i'm hearing more rattle and farting than i am smooth bass (which i hear if i put i ear close to the sub, so i know its not distortion)

Might be the rear deck. The cheapest way to get rid of that is to just slap some Paper towels between the metal panel, and the carpet part of it.

I'm going to try to explain this the best I can....

There are two vents with rubber flaps on them in the trunk, towards the back on the sides. I'm too tired, or I would run out and look so I could give you a better description of where. On my SVT they are easily accessible, but when I had my GL they took a little effort to get too. Anyways, ripping those rubber flaps off may be the cure to your problems. There are innumerable things that can rattle, but that was a major one for me.

Nevermind that's not what I was thinking of. I'll have to check again...
