Whats firing your engine ?

That is also what I would do. Just listen to your playing and you'll know when you are stressing the speakers.With the SVT-215E rated at 400W, you could go with 800-1000W as long as you watched how hard you pushed it. Remember, if you bridged the amp, you could get by with a smaller amp per channel rating as it just about doubles when bridged.

John- So you're saying 800 - 1000W per channel for the 400W 215? That's what I've been thinking about, I'm just not sure if it's safe for the cab or not. If it is, that's what I will do, as part of the whole idea is to not have want for more power anymore. Also, if I need to, this way I can add on another cab, and I do have my other 215 as well.
Well, overpowering a cab is just as destructive as underpowering or also evenpowering one if you push real hard. Underpowering and evenpowering will blow drivers when you constantly hard clip the amp and it is thus putting a flat wave signal through the drivers - that is DC and the voicecoils overheat and melt. With using a 800W amp with a 400W cab, you still have to watch pushing the cab too hard (it will "fart" at you!) as that will overheat the voicecoil also and melt it, but with the more powerful amp the risk is less because you will probably be too loud to tolerate it when that happens. Since you are listening to your sound as you play anyway, you can keep tabs on if you are pushing the cab too hard. The extra wattage will give you headroom for peaks that are not constant wattage and unless constant will not overheat the drivers.
I don't think you need 1000W with the 400W cab, that is a bit too much, but 500-800W would be alright, given sane levels of loudness.
Does that explain the relationship of power to cabs and damaging them?
The RMX 850 bridged would give you 830W into the 4 ohm SVT-215 cab. If you wanted to keep it two channel for bass/pa or using ROS with a second cabinet, then the 1450 would provide 400-450W for one channel, which would also be safe and loud (the SVT-3Pro is 450W into 4 ohm).
