HELP I think I have an electrical issue??

Could a common-ground explain the problem? Have you tried to lift the ground on the M60 Amplifiers?? Use a 2-prong adapter on each amplifier. It may improve the audio reproduction as well.

Well so far from what I have seen is that my dedicated circuits are both on the same side of the panel as the furnace is. I do have a gas furnace so the breaker for the furnace is 110. As a last resort I can look into putting the furnace breaker on the other side of the panel. (Is this what you were referring to Nosnhoj???)
Also one other thing to note is that my ground bars in my breaker are full and there is more than one ground in each one, including both dedicated circuits for my audio setup.

I have also switched my amps to the other dedicated circuit that is installed, and now the clicking noise the furnace starting is now coming through the opposite speaker.

Commcat,
So what if I use a 2 prong adapter and I find out that the problem is gone then how do I really fix this problem as I do not want to permanently use one of these adapters.

Oregon,

yeah, I actually did install them myself. by confirming the lines are dedicated, yes I believe they are.

I installed 2 20amp breakers, connected to each breaker is a run of 12/2 romex, then connected to a pair of hospital grade duplex's.

Like I said before all has been fine with my previous amps since I installed the 2 dedicated lines 4-5 months ago, and this just started yesterday when I hooked up these amps.

Strange that you didn't hear this with the prior amps.

I had exactly the same furnace ignition 'click' with my dedicated circuits. It is the grounds which are contaminated, they feed household garbage through the ground.

The only cure that I know of is dedicated ground for the dedicated circuit. Be aware this can be dangerous in lightning storms as ground potential differs between whole house ground and dedicated ground. Maybe lifting ground on amps will solve as well.

Except for I used Analysis Plus balanced interconnects before. Now that I am using the Genesis m60s which are unbalanced I am using a cheap pair NXG rca cables.

Are the NXG rca cables shielded? Try another pair of ics that are shielded.

Like I said before all has been fine with my previous amps since I installed the 2 dedicated lines 4-5 months ago, and this just started yesterday when I hooked up these amps.

Could be these amps are more sensitive to RF interference than the other amps.

The ignition spark on the furnace is high voltage and generates airborne RFI. It is also possible the HV spark ignitor is sending RFI back through the equipment grounding conductor of the branch circuit that feeds the furnace. When was the last time you had your furnace checked out? You might call someone out and have it serviced and have them check the ignition controller and the ignitor for a possible loose or corroded ground connection.
