Adding CD/radio to entertainment Center

There is space for a skinny CD/radio receiver in the cabinet over the TV.
I installed one with surround sound placing 3 speakers in the padded upper crown
molding over the table. The base cabinet sits behind the passenger's
seat, with an L bracket in the floor to hold in box in place, and balance of 2
speakers on end cabinets just beyond the big left slide. Wiring to the latter
was run through to ceiling conduct tubes.
