Amp recommendation 2xSA8 V1.5

Looking for some amp suggestions for my new setup. I think I have a short list of amps, so I'm just trying to make the best decision. I recently got a pair of Sundown SA-8 V1.5 subs. These are the 400w RMS models. Dual 2 ohm VC. I plan on wiring them to a 2 ohm load. I'm thinking I want/need an amp that does 1000 RMS @ 2. Car is wired with Knuconceptz OFC 4 gauge. Amp is getting signal from a LOC (want to keep my factory nav) wired into factory sub (its unhooked). Car is a 2012 Kia Optima with the factory Infinity stereo. I will be building either a shared box, or 2 boxes (1 in each wheel well "bumpout" in the trunk). Either setup will be ported. Just looking for a daily driver setup. Budget is $200 so I'm looking at used. So far my list has the following.

Alpine MRP-M1000

Hifonix BRZ1200

Boston Acoustics GTA-1000M

MB Quart ONX1.1500D

Kicker DX1000.1

JL AUDIO JX1000/1D

Soundstream Rubicon 1600

Any other suggestions? I know I have seen the Audioque 1200D mentioned as well but I'm not seeing any of those around used. Thanks for any help!
