    i'm only guessing so please tell me if i'm wrong... if i have a 300w head and 600w rms speaker i could buy a 300w power amp to boost the output i'm getting?? is that right or do i know nothing?? haha

    Your head already has a power amp in it; it's the internal component that takes the very small signal coming from your preamp (where all your tone knobs are ) and turns it into the very big signal that you hear from your cab. If you have a Line Out jack on the back of your head, you can run that into a separate power amp. It wouldn't be boosting your head's output per se, because you would be bypassing your head's initial 300-watt power amp section. Instead, you would be getting as much power as this external power amp would be providing, which would likely be much greater than your head's 300 watts.

    If you're looking for a cheap power amp, I've seen at least two Crown XLS models come up in the classifieds here lately; they're decent power amps for great prices.
