How to hook up my subwoofer

This is receiver thermal going in protect issue and has no bearing to your sub, The sub has its own power amp and not supplied by the receiver. Thermal module may be bad. See a tech.

Just use one of those jacks. Then turn the frequency select dial all the way up. This will work just as well.

I own 2 of these Pioneer VSX-D903S units.

The only way to hook a powered subwoofer up to a VSX-D903S is if your subwoofer is equipped with amplified/speaker level terminals on the back, in addition to the line-level input. If you only have a line-level input, do not attempt to hook it up to this receiver.

If you're lucky, and have speaker-level inputs on your powered subwoofer, you would use the amplified terminals (connect to B-channel on the receiver). DO NOT connect anything to the line-level connection.

Alternatively, you could build two unpowered subwoofers, then set the receiver's Impedance switch to LOW, then connect one enclosure to each of the "B-channel" outputs. Connect your regular left and right speakers to their corresponding "A-channel" outputs. [Impedance range: 4 Ohm minimum, 16 Ohm Maximum]

This is why they publish manuals.

The sub is driven by an OUTPUT of the Pioneer, clearly labeled "Sub Woofer"; and a single RCA cable would feed the sub's single Line In.

The manual for the SA-W2500 is here...

Probably, or the woofer coil itself is experiencing a heat, volume or motion related short. Clean any dust or debris from the heat sink fins in the back. Make sure it has lots of space for cooling ventilation.

Hi Nate. This is the cheapest remote I can find. http://www.avukltd.com/remotecontrolsearch.php?action=send_details&item_id=463947 Hope this is some use to you.

It probably buzzes all the time, you just notice it when it is outputting little volume. Check the cables for loose connections or replace them with other cable as a test.

I have exaclty the same problem. DVD into comp in 1, and my Homecast HT8000 into comp in 2 on my D912.

The dvd gets a picture.

The TV does not.

Looking at the settings I have "Component video Input" set correctly.

I'll add that when I do switch from DVD to TV, I get a scrabled vision of what is on TV for about half a second befoe the TV itself says "No, I can't display that" and gives me the blue screen of 'no signal'

THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.

Depends on what you have it hooked up to. Check wiring and controls if it is self powered. Check receiver/amp to see if it is outputting to subw.
