In cab gas tank cover ideas?

[Bullett]

Going to start my new carpet installation today and while I'm in the process, would like to figure out some type of cosmetic improvement to the in cab fuel tank. Some type of cover that blends in with the interior. Would also like to figure a way to get a couple speakers in behind the seat somewhere maybe? I currently just have a couple small kick panel speakers that just don't cut it. Just looking for ideas. Thanks...bullett
