Why do you want your subs presenting an 8 ohm load? If you want an 8 ohm load, and 300 watts RMS to each sub, you'll need a mono amp that can push 1200 watts RMS at 4 ohms, which is gonna cost a loooooot of money. I would instead run your subs in parallel (connect the + of the amp to the + of both subs, and the - of the amp to the - of both subs), which will present a 2 ohm load to the amplifier. Any Class D mono amp that pushes 600 watts RMS at 2 ohms will do fine. Even 500 watt RMS at 2 ohms will be fine.

Wire then to get a 2ohm load, and get yourself a monoblock D class.

More bass, less space, less heat, more efficiant!!
