When it comes to the BA system, we need to get one essential fact out to everyone who will be adding an amp to the factory radio:
There is a 6 volt DC (DIRECT CURRENT BAD BAD BAD) on the speaker leads in addition to the AC signal current.
Many, many amps cannot deal with this. Mine couldn't, it shorted and sent a power spike into the factory wiring frying the radio and the entire front panel/heater controls/screen. Took the dealer a month to get the parts in and repair it.
Even if using the ******** harness, one must use a LOC (low power output converter) to remove the 6vdc signal. Steve also sells a nice cheap LOC.
