Just a little confused im about to buy a phoenix gold zx475ti amp and not sure what kind of wattage I can get out of the amp using it as a 3 channel instead of as a 4 channel. Can some one tell me how much wattage I woud get from this amp if I ran 2 channels at 4 ohms to power 2 6x9's and the other 2 channels power 1 sub at 2 ohms

Here the spec on the amp:

-4 Ch. 500 watt Titanium Amp. W/Free LPL Remote TI500.4 (PreviouslyZX475ti)
-Dynamic Power (IHF-202): 4 ohm Mono 250 x 2 mono 2 ohm Per Ch. 150 x 4 4 ohm Per Ch.
-75 x 4 4 Channel Power Amplifier
-Increased Power Dead Silent Turn on/off
-TAIM Circuitry Variable Speed
-Fan for Reliable Cooling Better Stability
-Ultra Low Loads (2 Ohms bridged)
-Superbrite Tri-LED Power On 24dB Crossover (HP/LP/BP)with Aux Output
-Variable Crossover Range: 40 to 800Hz
-Dimensions: 16.0L x 9.8W x 2.25H
-Freq Response +/-1dB,20Hz to 20 kHZ
-Signal to Noise Ratio (A-weighted) 100dB
-Max Continuous Bridged Power @ 1% THD 250 watts x 2 into 4 ohms @ 14.4 Vdc
-Max Continuous Power per Channel @ 1% THD 150 watts x 4 into 2 ohms @ 14.4 Vdc
-Nominal Continuous Power per Channel @ 1 % THD 75 Watts x 4 into 4 ohms @14.4Vdc
-Power Rating 18 Watts x 4 into 4 ohms @ 12.5 Vdc

 

The TI500.4 makes

75W x 4 (4 ohm stereo)
250W x 2(4 ohm bridged)

So your front components (4 ohms) would get 75 watts each, and a single sub (4 ohm) would get 300 watts.

 

how many watts would I get if I ran the sub at 2ohms and the (2) 6x9's at 4 ohms?
