Poweramps take a line level output from a preamp. Try plugging a poweramp out into the input of another poweramp and you're looking at Blown Transformer City. And I'm not talking bout Optimum Prime's fave massage parlour.
you can take a preamp out from another amp, so's you can get it's sweet tones, and then plug it into the power amp in on your amp, for the ball shaking loudness.
Your PA head is a combined preamp and poweramp (like guitar amps).
The "power amp input" on the head is for a direct line to the power section, bypassing all the head's EQ shit, should you wanna use a mixing desk or whatever.
The thing on Ebay is just a seperate poweramp- to use it, you'd need to run an output from the preamp section of your PA head to the input of that unit, and connect it to a cab.
Don't do it Rob, y'dont need it, I can't believe you even use a full 250w RMS in an apartment anyway as it is..
Main Buss sounds like the preamp out, the thing you'd connect to a poweramp.
Just realise your PA head already has it's own poweramp that is more powerful than that unit on Ebay. The only way you could use it with your PA setup would be to run the PA head into ONE cab (presuming the speaker can handle the wattage and ohm load on it's own), then run a line from the MAIN BUSS to the Ebay poweramp, and connect that up to the other speaker (again, checking it can handle the poweramp's specs).
You could use your V-Amp thing (acting as a preamp) to plug straight into the Ebay poweramp, but it'd still need it's own speaker cab.

And then if you ran it that way, you'd no longer have the 2 speakers coming from the PA head, so your tunes you're running through it wouldn't be in stereo.
Give it up, brah! You don't need 400w+ for an apartment.
