I am thinking of getting the 500/1v2 amp as well as the JL 10W6v3 sub. I can only find that they have a dual 4ohm design which would make a 2 or 8 ohm load when hooked up, of course this would be 2 ohms load on this amp. I see that the THD is .05% @ 4-ohms (according to the website). It's actually rated at 500 W RMS @ 1.5 ohm - 4 ohm, so anything over 4 ohms may result in power loss and nothing else I guess.
