A general question relating to my plan to add Empeg to a new car as a secondary HU plugged into HU #1 -- the double-DIN Subaru WRX.... I'd like to make the empty sled less obvious during the times when the Empeg is not in the car.

Approach #1 would be to make the sled itself black. Black powder-coat or black satin spray paint would eventually wear in those areas where the Empeg rubs against the sled. A better alternative would seem to be some kind of black anodizing, but I know nothing about whether this could be done to the sled, which appears to be made of steel. Anyone have any experience with this? I expect that this would wear somewhat over time, but less so.

Another approach would be to make a plastic cover or (I'm thinking this would be more useful) to fab a black plastic/lexan insert that would form a dash cubby for spare change, pine tree deodorizers, roach clips, etc. Still, the latter approach would add one more thing rattling around the car.

Any metallurgical insights appreciated!
