You could extend the wires on the bose sub and amp and relocate it under the back seat. But I'm not really sure what all good it does. My Tahoe has the amplified bose system and I can't tell a difference.

As for the plastic piece all you need is the piece that goes from the glove box door all the way to under the climate controls. The piece that is under the steering wheel is seperate and there is no need to replace it. It is held together with multiple 7mm screws/bolts and clips along the dash.
