Doing it this way you wouldn't need the 4 ohm resistor in series with the 10" sub and you can reduce it's volume independently with the input level adjustment on that channel's input.
I think there is more than one "ds18 - 1200w" amp.
Since he said monoblock, maybe this one:
https://ds18.com/collections/amplifiers/products/exl-class-d-monoblock-amplifier-1200-watts-rms
Claims to be able to drive a 1 ohm load. Color me skeptical of a ~250.00 "1200W" one ohm capable amp, but hey...
It is a Class D (PWM digital) amp. Yes, Class D amps can be 1 ohm stable. Drivehard already mentioned using this kind of amp.
Actually, using a stereo amp wired the way that I mentioned would be a more elegant solution to his problem.
