I need some Audio help.

I have two small speakers and a small bass woofer. The spekers hate
any bass signal going into them. Is there a schematic for a simple
circuit I could use to pull out the bass from an amplified signal (15W
at 12V) and give the bass signal to the woofer and the rest to the
speakers? and beyond that would i be able to get stero sound from the
speakers and mix them in the woofer?

Start here. The search was "crossover network"

This guy is very good too.

I don't have a schematic for you but what you seem to need is called a
crossover circuit and further since you only have one woofer to share
left and right bass signals from a stereo source this would be a
custom crossover setup as well.

In theory it should work just fine as bass signal sources can't really
be discerned as well as higher frequencies so it wouldn't really
matter if the bass came from only one point. I have a 12 volt
subwoofer set up that has only one subwoofer and the sound is still
killer for example. All I would need is two high pass crossovers to
keep the bass out of my 6x9s and I would have basically what you are
talking about. Parts Express has a lot of crossover stuff and info
with a free catalog.

Yes, they call it a cross over network.

You can get ready made units for speaker builders.
or, use a capacitor in series with the smaller speakers
to remove the base how ever, this isn't as good like a
cross over that uses LC networks.

** Here is what you do:

1. Invert the signal to one channel of the stereo amp.

2. Connect 100uF non-polar caps in series with each stereo speaker.

3. Wire on speaker in reverse phase to the other.

3. Fit a 10mH iron core inductor in series with the woofer and connect the
combination across the two amplifier outputs.
