What kind of output watts? RMS, peak, Showroom :D ??
If its RMS that's a mighty power supply, 16 plus [email protected]+- 70V.

Out of curiosity, what are you going to do with that Amp?
someone else might help you with a circuit.

You can use LM12 from National Semi. in bridge configuration. Single LM12 can deliver 150W of power. For more details visit www.national.com

You won't get 2000W with it, but definitely more than what you currently have.
