OK, so I recently had to RMA my head unit, and I just got it back, and went to put everything back in, headunit works perfect, but low and behold my sub wont work. I checked all the connections. Amp has a green power light lit. I have the RCA's attached, and even tried hooking my MP3 player to the other end, thinking maybe my headunit wasnt passing along a signal. My MP3 player couldnt get it to play either.

So I brought my sub in the house, I ripped apart a PC subwoofer, and attached the red and black cables from its internal amp and it made my sub move and play just fine. So this tells me what ever the issue is its most definately the amplifer.

so, now my question is what would cause no sound to come out from the amp?

I have power/ground/remote attached, and the two speaker wires from my sub woofer (wired + + + and - - -) and there are 4 holes on the amp for speaker wire, but I wired it as you can see below.

Any ideas what could cause this?

sub is a w6 12 inch.

 
You can bring it any shop that can fix amps, they can generally fix the outputs. My amp had the same symptoms, the green light would come on but no signal would go to my subs...I have no clue how much it would cost, my guess is not much since nothing on the board is fried. I ended up just selling mine on craigslist for like $40

 
I noticed the db-r forum is down, but Chris did post a way to fix most of these amps. IIRC the daughter board coming loose was a common problem along with some solder joints needing to be touched up.

 
site appears up, but I cant find his thread, any chance you could link me? I have a soldering iron sitting right here //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
