RH450 Power recommendation

by idasys

I wish to push at least 800W from my rig. Is it cool to use a power amp in bridge mode with this unit as well as using 2 RH450 instead, and if so, how many witts should the power amp be? Example another 450, 800?

Are they planning on making a RH450 with more wattage soon?

RH800 3.0
