Thanks for the info everyone, bnoon especially. brad do u think this is something that one should tackle on his own or leave to the car audio installers for a professional job? I did a few quick searches for the Marhide products and didn't find anything so maybe you could steer me in the right direction.

I wasn't even aware that car audio installers did this type of work. How much should I expect to be charged? i'd appreciate any info you have, thanks much.
