Im not saying that this is their (Keystone) reason, but my B channel is for the bedroom. If you don't have bedroom speakers then perhaps they wire everything like on a assembly line. If you remove the four square head screws in the face, you can pull the unit straight out and you can attach anything additional to it from there.
The TV is patched into the RCA plug on the back of the unit, it will also play out of any set of speakers you choose, as will the DVD/CD
My radio is a Rockford, but I've been told that the Jenson is quite similar, so hope this helps
