KENWOOD SW 32HT Powered Subwoofer Plate Amplifier I tried to get the picture just go to ebay they show a picture of the inside

Was the fuse for the sub blown?

Hi,

You will always have voltage through the black incoming wire unless you turn your circuit breaker off. This wire will be attached to the common terminal on the switch. Is this what you were testing?
The power comes in the common terminal and then is switched through, or on, and broken, or off, when the dimmer is clicked. Therefore, there is always power coming into the switch.

Hope this helps, if it does, please place a vote for me. Thanks,

Disconnect its input cable to see if a true lack of signal lets it go to sleep. If not, it has a bug. Otherwise, you probably have some sort of signal present on the sub cable.

Hi,

there is a possibility that you may have pulled off the power switch, to motherboard Connector.
This will be at the bottom right hand-side of the Motherboard.
You should have a 2 cable connector for. pwr/sw Power Switch. hdd/led Hard-Drive led. rst/sw reset Switch.
Check those First. if you didn,t remove the power lead, before attempting any work. you may have arced a current, and damaged the motherboard Or PSU. check the Fuse In The Actual plug lead. to determine the actual power Switch, without a multi-meter. remove the power lead, from the Computer. remove the power/sw connector From motherboard, And Bridge the power/sw with A plastic jumper Block. then replace power lead, and should boot up. If it does the fault is the actual power switch faulty.

Usually, a subwoofer will have its own built-in power amplifier. Thus, it will be designed to plug into a standard RCA jack (the type used for DVD players, etc). rather than having wires to connect to a speaker terminal block. Look for a jack on the back of the receiver called "Subwoofer", or simply "SW". If your subwoofer has 2 single wires, it WON'T work with your reveiver's subwoofer output, as this output only carries a line-level signal and is not amplified. You would need a separate power amplifier for this type of SW. If your SW speaker has a DVD-type plug, it should work fine with the receiver's SW output jack.

Try holding down the set up button for 2-3 seconds. Press Dn or Up to select the subwoofer mode and the band button activate/deactivate SW function.
