KLH ASW8-100b Sub woofer. I need to know how to hook it up to my surround sound

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.

Some surround modes switch speakers on or off as required. It's possible that the inputs you are using have settings that remember your previous settings, ie: no sub and surround speakers. Check the inputs and also make certain that whatever is connected to them is putting out Dolby signals.

dose the sub woofer hooked up to the t.v.

This woofer was taken from a KLH Pro-71 Series. These were the top of the KLH line from ~94-99 when it was still a real company and not just a name. The woofer is rated for 5-350 watts at 8 ohms. Source: KLH Pro Series-71 Spec Sheet.

Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

How do I hook-up my surround sound system with powered sub woofer to my Sony stereo receiver and sony dvd player?

Is sub out turned on on the reciever? Some have a setting that doesnt use the sub out, like 2 channel.

Did you try making sure the subwoofer is turned on under the set up menu on the Sony Receiver?

Press Set Up, Press the left or right button above the scroll wheel until you get to SW. It should say SW: ON or SW: OFF. If it says SW: OFF, use the Scroll wheel to scroll right until it says SW: ON. Also, make sure you aren't in 2CH mode, try A.F.D or surround sound.

I got the same issue. But, I go ahead hooked it up two banana plugs on teh VCR outlet. It works fine on my Cerwin Vega Sub.
