It sounds like you have some problem with the subwoofer itself. The 950 can hang with the best of them, and it certainly will not cause pops in your subwoofer. I would investigate further, as what you are experiencing is NOT a characteristic of the 950. Try hooking the sub to other sources and see if it pops in those circumstances. A call to Outlaw wouldn't be a bad idea also, as they may have some suggesions to track down any potential problems.
