Add to that the fact that more than a few amps out of the Octane series showed less than stellar quality control resulting in a rather high premature failure rate and there's really no contest here between that particular PG and the Kicker //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gifkicker 400.1.
iirc that pg amp is only 100rms at 4ohm, 200 at 2. that 400.1 should show you at least 430 real rms.
NO 500Wrms is to much power for a maw-12either getting a kicker 400.1 or a PG R2.0;1 to power my MAW12. which would be the better choice? looking to get a clean 400-500 watts @2ohms
