Few weeks back I was cleaning up the cabling behind the rack. All nice and tidy running in flex tubing (keeps the misses happy).

I got lazy and didn't reach for the flash light. "There's the purple port" and I plugged it in. This purple port happened to be the powered port, not the pre-out port.

Amp is an Onkyo TX-SR806. Sub is a Onkyo SKW-204 from my first HTiB.

Few weeks back, my girlfriend mentions hearing a loud POP while watching TV (direction and source unknown). Everything seemed to be working fine so I figured it was just the amp switching formats and clicking, and her exaggerating :-D

Then we noticed that we were turning the volume up higher than normal. I check the speakers and notice that the sub was in standby mode. I run through the gamut of unpowering, trying different outlets, etc. I could get no sound through the sub. Triple checking the cables and finally reaching for the flashlight, I noticed where the sub was plugged in. It had probably been running on the powered port for around 3 weeks. maybe longer.

So I figure the sub is dead and order a cheap replacement. BIC F12 arrived yesterday.

I plugged it in (to the proper port) and adjust volume levels. The sub sounded great. Testing was done with Tron 2.0 as I wanted something full of low frequencies. We then moved on to the always sonically challenging 'Jeopardy'. Sound was good there as well. Next up, the torturous 'Wheel of Fortune', when I noticed a red glow from behind the F12. It was in standby. Changing channels, back to bluray on the ps3, nothing would wake it.

The F12 has a power switch on the back, I set it to on, still no sound.

It just seems like the Amp isn't sending anything over the subs channel. The display on the amp shows that the LFE channel is active. Menu screens on the Onkyo show that the sub is enabled. Going into the speaker adjustment page where the levels of each channel are set will turn the sub back on and produce the loud rumble. If you go back to viewing something though there is no sound coming though again.

I went to bed last night defeated. I'm thinking I will try resetting the amp. Blow out all my settings and start over.

Anyone have any ideas?

I'm really hoping I didn't kill my amp :-(
