It WILL run at 1 ohm. Birth sheet shows over 700 wts rms iirc (can take a look at it tomorrow). I'll do $140 shipped on this one! PERFECT shape, have original packaging and manuals/birthsheet!
I have a planet audio zetar sub and concept ca-502 amp I'd sell. they work great together and are both in great shape, even have the original box for the concept. 90 shipped for both to your door
so far FasFocus has made the best used offer dude.
i can do bnib full warranty ( vm is cheap but has no "real" warranty if you read the warranty terms its all BS ) for an hfi sub and a 500.2 amp for around that price send me an email not a pm if interested
