Ya that setup at 1 ohm is doing around 4400wrms at between 13-13.5volts or so and some are burping them at at .5ohm for closer to 4800-5000Wrms and one guy reported around 5700Wrms at 15.9volt while vehicle is running. Obvisously on a beefed up electrical system. Check them out at Sundown Audio or if you have any questions just PM me.
