What can this amp do on average? 4 ohms, 2 ohms, 12 volts, 14.4 volts all the way up to the max it can take. What is the max this amp can put out?

Well I installed one in my mom's truck. The birth sheet said it put out 868 watts at a two ohm load. I believe that was at 13.8 volts. I'm not sure how many volts you can feed it, but 16 does ring a bell. At four ohms I would guess that ours would put out around 110 watts a channel.

Right now that amp is giving 434 watts to 1 10" Kicker comp and 217 watts to each side for mids and highs. Seriously thinking about biamping those orion components.

I've heard people say that RFs are 2ohm mono stable as long as they have a fan on them. Is this true?

Rockford amps usually manage to survive at loads under their rated impedance, however it is important to remember that speaker loads are invariably always higher than the rated load, sometimes by as much as twice.

Also- If you are thinking about running subs with this amp, I would suggest going with a two channel, which is usually more stable and more importantly, cheaper :-)

I have the amp, the certificate said 924 @ a 2 ohms with 14.76 volts input. I will be running components off the front channels and a sub(s) off the rear. I am trying to keep it simple. Just wondering if I can run it 2 ohm mono off the rear and how much power I could get out of it. I am all for SQ so high distortion is not acceptable.

The Power supply is not as "beefy" in the RF 4 channels as in the t2. You could probably run either the front or rear into 2 ohm mono, but not both. if you want 2O-M power, go with a 2 channel model.
