Sub woofer works but when i add lil speakers no sound comes from them
SOURCE: loud humming buzzing sound coming from subwoofer
make sure you have the speaker connection right if you do then it is a ground problem try plugging it in a different outlet

Before you go throwing money at this problem, try to eliminate any external influences like track lighting. I myself am trying to figure out why mine makes a buzz throughout my system when the lights are on. I already replaced the variable light control with no improvement.
Bad cable ground can let airborne electronic noise into the Sub's amp.

I have the same problem. JavaMan is right. In one case someone even reported the bridge rectifier had failed. I have mine apart right now, trying to decide whether to attempt to fix it. The power board has been warped a little from the heat, and I can no longer read the color bands correctly on the power resistors to try to change them. Thanks for the schematics, JavaMan; unfortunately they don't match my boards, so I'm out of luck, and can't find anything else.
The components aren't expensive, so you might be able to take it someplace and have it repaired (or have a friend do it) fairly cheaply if the schematics here match your sub. I think I'm gonna chuck mine, which I hate to do since the speaker and cabinet are still good. I've just wasted too much time on it, and already have another in its place.

Some specific model numbers might lead us to specific manuals and specific instructions. To find a manual, maybe run it by the manufacturer
Depends on your source and its amplifer complement. Some can drive a subwoofer directly while others just produce a Line Level subwoofer output for use by a separate amp feeding a subwoofer or self-amplified sub.
The set-up of the source to produce a subwoofer output is totally dependent on its design. Generally, you have to 1) tell it you have a sub, 2) define how bass will be routed or shared among your various speakers accordingto their bass-handling capacities, 3) using test tones, set the relative ludness and crossover settings so you have a uniform sound field.
