Trying to hook up a KLH sub woofer, S100ETH, PSW8-100 to a VCR reciever. Reciever has sub woofer connection but does not works on the KLH sub woofer. What is the problem ?


I suggest you go over your receiver set-up instructions. See if you need to set the receiver to acknolwedge the addition of the subwoofer. It should be in your receiver set-up steps. Just as a check, hook up one of your other speakers to the subwoofer lead to see if gets audio signal. I'm guessing the issue is your receiver settings.

How do I get sound from my subwoofer


Need more info, is it powered or passive, is audio making it to the speaker cabinet? Make sure by hooking the wires or cable to another speaker. If you have done that already then it is time to see if if the voice coil is burnt(indicating the sub was played too loud too long). Access the speaker and gently push on the cone. Any resistance or scratchy sound would indicate a burnt VC. Time to replace the woofer. Any other problems you would need to be much more descriptive. Make, model, how you were using the sub when it failed, etc.

My sub woofer making noise like machine gun w out connect toamp


Disconnect the sub-woofer and see if the noise stops, if so the amplifier is OSCILLATING and so produces the noise.This can be related to fault with the pre-amp or audio processing section. Try and heat up the circuit using a hair dryer and if the fault clears then there are faulty electronic capacitors. If leak is seen then the pcb must be washed after the capacitor is replaced which can solve the issue.

My receiver dies every time I attempt to plug in the stereo wire into the receiver (the other end is already in the subwoffer)? Is there something wrong with my receiver or am I not hooking it up...


your sub woofer is partly shorted check the output transistor of your sub woofer before pluging to the receiver or this will damage your receiver

Bose acousticmass 15 sub-woofer making a noise


The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

Sub woofer keeps blowing fuses


NO dont try a 3 amp fuse.It is made to BLOW if there is a problem. That sub is not worth fixing, JUNK it. There are a lot of problems with it. Such as heating up and melting the board witch could cause fires. Thats what happened to mine. Like I said JUNK it and buy a different one.
