My buddy had a rack rig for his ampeg 8x10 and this is what he used to power it. Amazing clean sound! If you have a crossover to subwoofers, you won't need a 500W per side 8 ohms power amp for 500W speakers... unless you run full range with bass cranked.

Many people don't read the manual. But I took the time to read mine this morning when I got it. You can make it so Ch 1 is input, and Ch 2 is output on the TRS 1/4" plugs, so you can chain as many amps together as you want! This is a nice feature if you bridge mono, or if you run alot of monitor amps under one submix/aux channel on the sound board!

I purchased the RMX 1850 HD a few months ago and paired it with a Behringer 32/42 Channel board. I use it to run my mains that are JBL JRX125 3 way 15" speakers. All I can say is WOW. I can rock our whole building, True Intense Bass and probably could get away with out even buying a sub. I am going to buy another to power my 4 stage monitors and then another to power the monitors for the musicians. Great Price and Great Quality. I have used QSC amps for over 12 years now with Great reliability.
