Which MMATS amp for JL 10W3v3?

I have a JL 10W3v3 4Ohm that needs an amp. I am planning on getting a MMATS HiFi 6150D for my 3-way AF components up front. Wondering what amp from MMATS will pair well with this subwoofer?
I was looking at their M-series but their power is rated at 1Ohm and 2Ohm. I'm not sure if it's okay to buy an amp rated at 2Ohm to power a 4Ohm sub (and if it is okay, how to calculate the 2Ohm power to run my sub)

Budget would be nice to keep below $600, but I still like to know what would go great with the JL.

I would say an M1000 should do it and then set the gain for the 500 watts RMS that sub is rated for. I would consult MMAT’s direct or one of their dealers on what the 4-ohm rating actually is but It’s likely at least 500 watts, probably much more.
