the only thing i could think of is your subs can't handle the power your amp is putting out. but i suppose i would have to take a peek at it in person.
do you scrape alot since your sportlines were installed? i don't want to drag anything.. lol
and yes, gloss black trim would be really sweet. i planned on doing that. i wanted to just replace everything with black SVT trim, but it's almost impossible to find a black partout.
