pioneer receiver subwoofer output not working

Asking an AV receiver to drive full-range speakers to play low frequencies with authority puts a real strain on the amps and robs the midrange drivers and tweeters of the power they need to create an expansive soundstage with massive dynamic impact. Even worse, attempting to reproduce those subterranean tones requires a huge amount of amplifier power. When many large, so-called full-range speakers try to deliver deep bass, they can sound distorted and overworked.

Does anyone else have any other things to check? I want to make sure i didnt overlook something. My best conclusion at this point is something blew in the receiver that ended up blowing the woofer. Under the level calibration it plays white noise for each speaker and when I get to sub I think I can hear a little bit of something if I put my ear right on to the box, but obviously I shouldnt have to do that. I also checked to make sure the speaker configuration in the setup has the subwoofer output on. I also hooked the subwoofer directly to the cable box sound output (it sounded bad because there was no crossover but was still getting sound). I can get normal feedback sounds if I dont push the connector in all the way. I hooked up the subwoofer and still got no sound. I check the Impedence with an ohmeter first and the busted speaker read 3.4 Ohms and the good speaker read 3.7 Ohms. I considered the possibility that maybe the amp in the old box was no good so I swapped out the good woofer from the old box and hooked it up to the Infinity box. I cannot say for sure but I could swear that before I swapped them the Infinity sub, though torn, was moving. I checked the level knob on the back of the subwoofer and the subwoofer level in the receiver setup. I swapped it out with an old powered sub box I had laying around and I was getting no sound. I am not sure the model number but it is an Infinity powered sub box. I checked the sub and sure enough it had blown. Last night I noticed during loud scenes (think explosions) I started hearing a flappy sound. I have an Onkyo TX-NR636 that I suspect is not outputting a subwoofer signal.
