I have a 1100 watt rms memphis and I have 6 12s hooked up to it at 375 rms a piece. I'd like to add another subwoofer that people I know run on 5000 rms(atomic apx 18). The reason being one box is tuned very high the other is low. Could this work? If not would my amp go into protect? Also I have two sets of speaker terminals. Thanks for any help. Btw this is just temporary
