TCHconn — Have you looked at the AV system's own trouble code readouts? They are separate from those of the car. I'm attaching three sets of Repair Manual pages that address how to do this, how to interpret the results, and how to remove/install the amplifier (there's no need to remove the passenger's seat to do this).
