It does seem weird. I noticed from your signature that you have Polk Audio SDA SRS speakers. I am a vintage Polk owner (RTA-12Cs) and have heard some SDA owners at the Club Polk forum mention amp shutdown problems in certain configurations.
If you didn't change anything there, I guess there is no reason to suspect that, but I thought I'd give you another place to look. Good luck and let us know things turn out.
it's true.. the SDA's need a common ground amp... or the amp or speakers could be damaged if a non common ground amp is used.
Most people think the SDA"s need tons of power to run them.. yes more power is better. But i have run my SDA SRS"s with as little as 45wpc. Using an old Yamaha int amp. As long as the amp can handle a 4ohm load.. and is common ground.. they will run the SDA's.
