Earlier today I noticed a steady popping sound (about 30/min) coming from my EP125 while it was idle. I disconnected everything but the power cable to see if there was a signal causing it, but the sound persisted without any signal. When I turned the power off I noticed the back panel was very hot to the touch (too hot to keep my hand on it for 3+ seconds).

Does anyone have thoughts about this? The woofer is fairly new - <3 months.

Thanks,
Adam
