Actually, I found the whole datasheet for the amplifier (unless there's
more than one STK4132II amp in the world), the system is a Sony but the
amp is made by Sanyo...whaddyaknow.

From my basic electronics knowledge, it doesn't look like it's a
bridged amp.
But if someone is actually interested in examining the circuit diagrams
and verifying, that'll be cool. Maybe you could spot some design flaw
that'd explain this behavior :-)

Thanks for the replies, I'll try the grounding workaround.

I'm not familiar with the particular unit, but I wouldn't attempt this if it
uses bridged amplifier outputs like some do.
There aren't any "G" connectors in that case of course, but then most amps
don't have terminals actually marked "G" in any case.
