OK, thanks guys. I will take it up with them and see how it goes. It's just a royal pain and sure seems excessive. 2 amps in under 5 years? I'm happy with their service so far and happy with the rest of speakers...(I have two rooms with all Axioms in 5.1 M-80's VP-150 Q-8's EP-600 great room and M-22's VP-100 Q-4's EP350 bedroom).....but this sub has me thinking of changing to something else. Love it when it works but having to worry about it....again....sucks.

Do you guys leave them plugged in all the time and turned on? I have always done this and never thought twice about it until now. I bought my old M&K 350 almost 20 years ago. It's been moved through 3 houses and across the country and always plugged in and still works flawlessly. This EP-600 has been in the same spot since day one and seems to be biting the dust again. Roughly 2 years to each amp. Bummer.

Just seems really abnormal. Wish I had a definitive cause.
