Faulty amp?

Hi guys,

I have this weird problem that has me baffled. I have a polk momo mm2104dvc sub which was powered by my c300.2, no problems whatsoever.

Ive recently acquired a c500.1 to power the sub. I did a straight swap between the amps and all is fine... When the headunit is on. When i turn the headunit off the sub makes a sound increasing in loudness ending in a extremely loud pop. This repeats continuously until i turn the headunit on.

There doesnt need to be any music playing or any volume level set on the headunit. It simply needs to be ON. As soon as i turn it off the symptom reappears.

Im using speaker level input as the stock headunit does not have a line out. The ground has been checked. The remote lead is connected to the vehicles accessory lead.

I have swapped the amps back ie. Connected the c300.2 to the sub and i dont experience this. It only happens with the c500.1

Any suggestions/help would be highly appreciated as I am at my wits end.
