Hello all, I have recently been experiencing occasional popping in my rear speakers when I turn off my amplifier. I had this problem before when I was running a passive sub off the same amp. To correct that, I removed the sub from the amp and turned the gain down all the way on that channel, problem solved. Now that the rear speakers are doing it, I am wondering if there is a problem with the amp or if I need to re-work all the interconnects and or speaker cables.

Info on my system: 990 processor
parasound 1206 amp
Infinity kappa 7 speakers for LCR and kappa 6 speakers in the rear.
