Yellow and black is 12V, red and black is 5V, according to my DMM.

Wade:
Thanks. I'll check the wattages and amps on the amp and power supply tonight.

Example:
The voltage regulator in PS#1 is +12.005v
The voltage regulator in PS#2 is +12.000v
Hook the two of them together and you would think that it would balance out somewhere between those two values.
But then PS#1 thinks the voltage is two low and tries to bump it up.
And PS#2 sees too high of a voltage and tries to drag it back down.
What started out as a voltage diff of only .005v could easily become a Catch22 of several volts. :o
Eventually one of the two is gonna fry the other as they fight to maintain what each one thinks is the ideal voltage.

Would the power supply even notice a voltage difference? The amp probably will be sucking up all the juice anyway.. where would the return voltage come from.. the ground?

Can't you just get a 10W 4ohm dummy load from radio shack?
then drive the damn thing w/whatever.....

I don't think I quite understand... what's a 10W 4ohm dummy load? I got the 10w and the 4ohm part... but how does this fit into the equation?
