WTT: PPI PCX480 for decent plate amp.

I have a plate amp used to power a 15" subwoofer in a Acoustic Research 315OH speaker. It is rated at 500 watts. It has no external adjustments for x-over frequencey or bass boost, but I think internally you can adjust them, although I'm not sure.

Hmm, that might be more power than I wanted, any chance you can take a look at what is adjustable? Bass boost isn't important but I was hoping for x-over adjustments.
