honestly i dont think it puts out the full 1600watts..but lets say even if it gives 1400 watts thats still 700 per sub..there rated at 750-1000 so will it work? sure..will it push them to full potential..i dont think so..what i would suggest is first go with 1 L7 and see how it works for you..if you feel you need more then go ahead and get another..
