thought i'd try plugging my gallo subamp into my gallo 3.1's the other day and got a horrible buzz out of speakers (sa not even on).

pre is a Decware csp3 using the mono output and Y-rca to gallo SA.
the stereo outputs going to khartago monos.

I've used this subamp many times with various stereo amps with no problems.
It also works ok with driving a passive subwoofer using the decware mono output.

something about the csp3 and mono amps not liking the gallo sa????

With the amp not even on, I'd say you must have a grounding issue somewhere. You might try using a ground lift "cheater" plug on the power cable of the SA amp.

Yes good idea.  Thats kinda what I was thinking too.
