The CXA1250.1 gives 1200 watts RMS @ 14.4 VDC. Best expectation is 80% efficiency which is 960 watts RMS @ 14.4 vdc. In a real world automitive environment, the supply voltage will range from 12 vdc to 13.8 vdc with a good battery and alternator. That means you'll get something proportional like 800 watts RMS @ 12 vdc. You will be getting 1600 watts peak. This should be plenty of power for one of the specified subs. However, if you want a 100% constant 1000 watts RMS, you'll have to step up to the 1800.1. I am pushing 900 watts RMS to a 1.33 ohm setup (3 300 watt 10's in parallel), and this amp is absolutely incredible! For the money, I dont think you'll hear or be able to get any additional performance out of the sub with the 1800.1. This amp will be plenty of power to get great performance out of the specified sub...
