Subwoofer not recognized and no sound from tuner

My subwoofer was working prior to a ypao session. Now my subwoofer is not recognized on the display (as well as no sound). I have the subwoofer "on" in the speaker set up. The power led light on sub went from green to red as well when I noticed it not firing. The light is green now, but no difference. Also, I don't sound from my tuner anymore.

Do a test tone which will test all speakers connected to the receiver.

SOURCE: Bose Acoustimass Subwoofer not working; front/center are working

From the speaker output from your amp, connect left and right to the sub box. Turn on amp and try to play some music. If the sub is working, turn amp off and connect the satellite speakers and turn amp on. Make sure amp is on speaker "A" and the lines are coming from the same connectors on the rear of amp. Check your amp with another speaker to make sure it is working if you have no output. Does the Bose box have its own power cord (self-powered)? If it is self-powered, the internal amp might have tripped or is not working. If unit is not powered, the crossover or thermal protection could be damaged. Refer to Bose for parts.

SOURCE: no signal on subwoofer out in Onkyo TX-SR703(E) - similar to TX-SR803

Hey Tad, I have the same problem and perhaps a solution. I just moved to the other SW "pre-out" and it seems to be working..the green light is on . Whatever works i guess.

SOURCE: Onkyo 805 sub hook up problem

I made the same mistake when i hooked my REL sub up to the back of the 805.

The problem is there are 2 connectors on the back of the amp that are labeled as sub out. Look very closely, you will see that there are 2 grouped RCA outs. The RCA out group you are looking for differentiated by groups of "little white dots" all the way to the far right on the back of the amp. Hope this helps.

SOURCE: Kube 2 subwoofer hum

The Kube Sub-woofer is earthed via its 3 pin plug. The Onkyo and other components I have in my system are not (they are double insulated). During normal operation, a difference in electrical potential can exist between these components in the system. I found that this potential was finding a path to earth via the audio cable and on through the subwoofer's earth. The path was via the earth portion of the audio cable and so gave the hum irrespective of volume levels set either on the Onkyo or the sub.

The fix is to ground the Onkyo to the sub. I used a length of electrical cable between a panel mounting screw on the back of the sub and a screw on the casing at the rear of the Onkyo. Try it out with a piece of cable manually touching screws with the bare ends of the cable until you find ones that give continuity( the hum will go immediately). I then crimped a small fork end electrical fitting onto each end of the cable which can be slid under the slighly loosened screw head and resecured. All I hear now is the fan on the Blu-Ray player!

Most likely, the "remote" wire to the subwoofer amplifier has come off or is not making good connection.

My subwoofer will not work with my receiver.


I had a similar problem where the subwoofer was working during calibration but not on TV viewing. Here is what I found:
  • That some listening/surround modes did not support the subwoofer.
  • Some receivers only support subwoofer with digital inputs.
  • Might also want to double check the speaker config and make sure it's has the subwoofer enabled.
  • I assume you're using the sub-pre-out to drive the powered subwoofer.
  • Have your tried a CD or FM radio station to see if you're getting the sub output from these sources?

No sound when hooking receiver to subwoofer using standard red RCA cable. Do I need a subwoofer cable?? I have turned my tuner subwoofer to YES, powered up receiver and subwoofer but nothing.


Probably not if it takes RCA input, but the receiver needs to be informed of the sub's presence and hw you want to share low frequencies among the rest of the speakers and itself. Then you need to set the relative levels using test tones, which also proves the sub works.

My subwoofer makes loud, sharp popping noises at random intervals when in use. Otherwise, the sound is performing as expected. Any ideas on what the problem is?


Pull the board out of the cabinet and spray it with "Tuner wash" can be found at any electronics store like Radio Shack etc. make sure you spray it on the volume and crossover point controls. Beware, Tuner wash can eat thru vinyl and any writing on the plastic. Pull off what you can and tape off the rest if necessary. After spraying it down, work it into the controls by turning them up & down. The spray will evaporate quickly. If you still have an issue, post a comment and I will help you troubleshoot further.

Philips DC912/37 will not pair with the subwoofer. I have had the device for 2 years, and the subwoofer stopped working recently, and now it will not pair with the tuner.


This worked for me. Try it and it should work for you all as well..;-)

Frequently asked questions See all FAQs Question How do I get the main unit to recognize the subwoofer? Answer Wireless connection will set up automatically when you switch on both the main unit and subwoofer.
Sometimes you may encounter the problem that the main unit does not recognize the subwoofer. Try the following process to solve the problem:
  • They are heavily interfered by other wireless home appliance such wireless network, TV etc. Move the subwoofer to another place, the main unit will auto detect & recognize it.
  • Switch off the main unit and the subwoofer and then switch on them again. The main unit should recognize the subwoofer automatically.
If neither of the above works, try to pair with them manually.
  1. In standby mode, press and hold the 090518075138_27245.gif button on the main unit (PAIR flashes on the display screen.) to activate signal transmitting.
  2. Press and hold the PAIR button on the rear of the subwoofer (You will find the LED indicator on the subwoofer flashes in blue and green alternatively) to activate signal receiving.
The wireless connection will set up automatically and the main unit should recognize the subwoofer now.

I have the same speaker and it sounds like its behaving properly.

if you look on the back of the amp, you will find a switch that allows the speaker to automatically switch the speaker on or off based on the level of the audio coming from the tuner that it is attached to. If the switch is set to the auto mode, then it will listen for audio on the line and if the signal level coming into the subwoofer is high enough, the amplifier in the subwoofer will turn on and play. If the signal is not strong or loud enough, then the subwoofer will not turn on. There are two solutions to getting the speaker to work.

1. When you turn on the tuner or audio source that is feeding the Subwoofer speaker, you will need to turn it up loud enough to trigger the circuit in the subwoofer to switch on.

2. Alternatively, you can bypass the automatic circuit and set it to the "ON position all the time. In this position the subwoofer is always ready and waiting and should play any signal that is fed to it regardless of the loudness or volume of sound from the tuner. The switch is located on the back of the speaker cabinet just to the right of the red and black speaker wire connections. It is labeled "AUTO" and the switch positions are labeled ON and OFF.

Hope this helps!

Crackling Sound From Subwoofer


Check any wiring coming or going to the subwoofer. It sounds like it could be a loose connection.  Is there a LFE or bass boost knob on your subwoofer? Does turning that up/down cause the crackling (if it exists). If so, you could use some tuner cleaner to clean the contacts on the potentiometer knob.

If the crackling is on the subwoofer only, it might be damaged from bottoming out.  See if you can remove the baffle or grille covering the woofer and inspect for visual problems. You can also try to lighly push in and out on the subwoofer to hear if it makes any scraping sounds. If so, it is definitely damaged and the driver will have to be replaced.
