I have an onkyo 602 and an infinity ps-12, both of which are about 5 years old. I noticed that my sub was cutting on and off every couple of seconds. I switched the cable, and then tried a Y adapter and increased the power, just in case it was a signal issue. the same thing happened. so, the question is: how can I tell if it's an issue with the sub, or if it's something at the receiver level? I'd hate to buy one and find out that the other is the culprit. no other issues are present, and the sub operates normally when the signal comes in. also, there is no auto detect option...it's an off or on proposition.
none of my friends are into HT, so I can't just haul the sub anywhere to try it on a different receiver.
thanks for any thoughts.
