the panels in my 40 were shot. for a temp fix i made them out of a cardboard box and painted them the same as the cab. since then i got a pair of abs panels and a pair of abs speaker pods from "rod doors" painted the panels and the pods same as cab color. now i have a good sound system that is neat, clean and almost hidden. i mounted a removable cd player that is wired for the ashton. with the addition of an ipod no more skipping plus the music drowns out the sound of the engine when at cruising speed.
