On Phoenix's website, they actually list a class-D mono amp, model R 2.0:1 as having 200 watt output PEAK into 2 ohms. No other specs for power. Does this mean 100 watts PEAK into 4 ohms, and like maybe 50 RMS watts at 4 ohms? What do they think I'm doing, using a 6 1/2" for a sub or something? That hardly seems like it's worth hooking up to a sub at 4 ohms. And especially making it a class-D amp. I thought these were supposed to be better and more efficient than a MOSFET amp.
Also, their R 9.0:5 amp, a 5 channel amp, says it's 125 x 4 PEAK at 4 ohms, and 400 x 1 PEAK at 2 ohms bridged. HELLO....it's a 5 channel amp, you can't bridge it. And even if I misunderstood somehow, would it be bridgable at 2 ohms?
Also everything is rated at PEAK powers, no RMS listed at all. That plus all the inconsistancies, and the low prices compared to high end features like being class-D makes me think these could be cheap amps.
Should I assume that, or chalk it up to the website having not enough information, and some misprints, and still consider them?

RMS power is half the PEAK power, 99% of the time.
Yeah that first amp would be 50w RMS @4ohms.
Efficiency matters regardless of wattage, its always a plus to have a class D amp.
I'm really not even sure about that second amp you mentioned, like you say, doesnt make sense.
SOME models of Pheonix Gold amps are reccomended, others arent, i'm not gonna be the one to tell you not to buy their amps, but it looks like you've got the correct assumption that those 2 particular amps aren't the best.

How do I delete it? I logged in and clicked "delete" but it just took me to a page with a big "help us to help you" post by swez on it. There was a picture of albert einstein on there too in cartoon form. No deletion options. I don't have a gold so I don't have any real options.

Well, I posted that on the wrong one, but you get the picture I'm sure. The other post needs deleted, not this one.
