Answer 1

You can wire a dual 4-ohm voice coil for 2 ohms by wiring the coils in parallel. Here's a diagram:

It should sound fine with a 300 watt RMS amplifier. Ignore anyone who tells you it's dangerous to underpower a subwoofer; 300 watts will get plenty of output from a Type R if the gains are set right and if it's in the right box.

Answer 2

I have the same Alpine Type-R 12" sub. The box that the sub came in comes with two wires and an instruction guide to bridge it down in parallel without adding an additional sub. Also, I have a MRP-650 Alpine amp that produces 600 watts @ 2ohms and the sub takes every bit of it with no distortion, so you'll be just fine.

If you have a sealed box, be sure to use some polyfill in your box so you achieve the highest amount of clarity from your sub/box as possible.
