    I'm having the same issue...my subwoofer will work for a few minutes, and then turn off automatically. It will turn back on (temporarily) if I take out and then plug back in the system cord.

SOURCE: No power to subwoofer

The subwoofer is designed to be "on" at all times. It will detect signal from the cable and should start by itself. So yes, the pin cable must be connected.

Hello, it,s very possible that it,s circuit protector built in to the sub (if it,s a self powered sub) gets to the point of overload and shuts off as a protection so that the speaker won,t get damaged and also so the internal amp tha,t pushing the speaker sound is also protected since theese amps all have heat buildup, their are two types of subwoofers ,They are the powered ones and the ones that are powered bt the surround amp ,The ones powered by the stereo surround amp/tuner tend to throw out less power to the sub and the ones that have internal power are mostly higher powered , Another thing you might want to check is your polarity to the speakers and also the omage , Most home theater system speakers are 8 ohm,s but their are speakers and amps that can be changed to 6 ohm,s ..so you might want to check the speaker rating also . Well hopefully you can use theese different methods to at least troubleshoot and discount the thing,s that are not the issues , Good luck and hope theese sugestions might help you , Sincerely Glenn

SOURCE: Sub woofer its on for 3 sec..

your cooling fan is not engaging and coming on like its suppose to. One, the fan is probably burned out, which sucks because its low voltage and the only thing on the board that is low voltage. Two, there is a thermostat type component that tells the fan to start which HAS burned out and doesnt start the fan accordingly. If you look at the back fan and turn everything on you will see the fan either doesnt start or starts right as the relay trips turning the sound components off. If it starts at all your fans good.The thermostat component will need to be replace and I cant recommend a source. Just trying to explain the problem so you can look for the right repair. Hope it helps. I have one of these and have found this is the problem, but cant find the solution.

Hello Guys,Can you please help? can I replace the sub woofer on my sony home theatre system DAV-DZ231 with a Celestion sub woofer s10


Presumably, the Celestion subwoofer is self-powered in which case it would connect to an RCA subwoofer output on your Sony system if there is one.

I have a Bose powered sub woofer, which I would like to connect to a pioneer receiver, the subwoofer (model 2683) connection has a four pronged connection (yellow white red blank) and the receiver has a...


Hi,sorry but you can not connect it directly like other sub-woofers..
Bose 2683 Powered Subwoofer is part of Bose Lifestyle 5 system, Please note that you will need the 5-pin DIN cable that connects the subwoofer to the base or "Music Center". and the 4 pronged connections for its own stereo speaker output not input from another stereo..
Sorry....but if you can arrange some handy man nearby ,he may get into the DIN cable to locate the subwoofer signal 2x input leads than you can use that leads for connecting into single sub woofer out let of your system...otherwise try to sell BOSE which can easily buy brand new up to date powered sub..

Connecting a Sony Subwoofer SA-W2500 to a STR DE 598


It is based on your sub-woofer type..whether powered or passive sub woofer..
Assume that you have powered one..RCA sub woofer jack is the best to feed it ..you should use RCA sub woofer output on your receiver as well..good luck

Connection of a subwoofer to Yamaha ZX-V490


Get a powered sub-woofer that has speaker level inputs, then run your front speaker wires into the sub-woofers speaker level input and then run a set of speaker wires from the sub-woofers speaker wire output to your front speakers. This is a common way to use a sub-woofer with a receiver that doesn't have a sub-woofer output.

Most powered sub-woofers have these connections, just check it out first before you buy one. They look like speaker jacks on the back of the receiver.

Let me know if you have any other questions.

Hi I own a Technics Hi-Fi system (Model SC-EH780) and would like to attach a subwoofer to it. I cannot find the subwoofer unit that is supposed to go with this system. Can you help?


Any powered sub-woofer will work with it. Check the back of the Technics, make sure there is an RCA output labeled "Sub-woofer" or "Woofer" or "Sub". If so, you can get any brand of powered sub woofer and it will work. A powered sub-woofer is one with an amplifier for the sub built into the box and you will need to plug it into an A/C outlet as well. The only exceptions to what will work with this unit is to make sure you are not buying a sub-woofer that is made to only work with the companion unit it is originally sold with. Many Panasonic and JVC sub woofers are like this. Just look for a sub-woofer that is not part of any system. Velodyne makes some really great sub-woofers that would work nice with yours, but they can be a little expensive, but they are very good.

If your Technics has no RCA output for the sub-woofer, you will need to make sure that whatever powered sub-woofer you buy has a speaker level input for it. Most powered sub-woofers have this feature, so that you may just run the front speaker outputs of the receiver into the subwoofer and then the sub-woofer will have a set of speaker outputs right below the speaker inputs so you can still have your front speakers connected to that and not loose anything from your system.

I hope I have explained this in a manner you will understand easy, if not just post whatever questions you may have right on this thread and I will get back to you as soon as possible.

It would also be appreciated if you could rate this solution if you no longer need any help from me. If you do require more help, please wait to rate this until we are finished. That way I do not get an undeserved bad rating when we have not even finished our communications.
By the way, A "Thanks for trying" and "Helpful" rating are really not good, they always end up lowering my overall score.

SA-AX720 no subwoofer 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.

Hi - You can download the manual by clicking the link underlined in blue below:

RD-6108

Your sub woofer needs to have it's own power amp i.e. a "powered" sub woofer:

Assuming your sub woofer is powered & connect as shown then check the following setting:
