Tbh even though your subwoofer is only 250 watts RMS I would still get something a little more then 300 watts maybe a 500 watt amplifier so you have some headroom and the ability to upgrade the subwoofer if you want down the road. Always better to have more power available then not enough. I would consider any of these below
The 1st one is a Rockford Fosgate that has 300 watts RMS at 4ohms & 500 watts RMS at 2ohms
This one is a Kenwood Excelon X501-1 which does 300 watts RMS at 4 ohms and 500 watts RMS at 2 ohms

This one is refurbished but JBL makes a decent monoblock as well.

Personally I think I would go for the Pioneer below, 300 watts at 4ohms, 500 watts at 2ohms and 800 watts at 1ohm. Giving you quite a bit of room for upgrading the subwoofer down the line. Obviously check all places for the price but
Sonicelectronix is a great place to buy from.

Amazon has them for 199.99 and have 4 left. Pay attention to the RMS ratings that is what matters. Plus they have tested higher as well by Williston so you have headroom as I said above. Really nice amplifiers all around.
