I'd like to trade this amp for a high quality sub amp. It would have to be capable of at least 750 w/ch at 2 ohm stereo , or 1500+ w x 1ch at 1 ohm mono. Amps considered would be along the lines of PPI PCX2350 ..... RFT20001BD ...... IA 20.1 , US Amps , ect ......
I prefer two channels over a mono amp ....

Here's the actual birthsheet for this amp ...... It does NOT show 4 ohm bridged. However the 2 ohm stereo rating is exactly 12 % higher than what it is rated for. Going by that figure , and considering it is rated at 320 w/ch x2 at 4 ohm bridged , it should be putting out 384 w/ch x2 at 4 ohm bridged .... when the 12% is added in .....
