[QUOTE="VereChronicus, post: 1559858, member: 565864"] You definitely won't hurt the sub with lower power and your amplifier will push closer to 800-850wrms @ 2ohms. It is not one that doubles in power from 2 to 1ohms despite the ratings. The ratings are for USACi style competitions where they go by the manufacturers 4ohm output rating. That amp will put out about 425ish into 4ohms. There are tons of myths floating around out there about low power killing subwoofers as well as 50k other myths on different subjects. It's common, but it's not true. With the same alternator, and the same amplifier, at lower impedances there is MORE distortion, so going UP in impedance from 1 to 2ohms, you will basically cut the distortion by 1/3rd in this instance. For extra information, to give you "ammunition" or knowledge for future dealings with local shops and the many myths and possible sales traps......
