Nm, figured it out disconnected hdmi on the TV was causing the induced hum. Lol Everything is working great!!! 5.3.4 Definitely upped my bass game. Thanks for everyone's contributions.

I really appreciate your workup. I just did this myself. I have a Denon AVR-X4400h driving my home theater. I purchased an open box crown 1002 xls amp for a good price. As soon as I plugged in the amp(still powered off) I am getting slight electrical) noise on all my speakers. I set the crown to y mode using sub 2 out on the denon (LFE) no crossover setting 1 and 2 on the crown (no sound from subs powered on). I'm guessing maybe I got a bad amp :(? Anyone have any ideas?
