im looking to buy a 10" type-r sub and a mono channel amplifier(Alpine MRP-M500)..my question is which combination to buy to produce the best SQ, the sub is a dual voice coil and is available in 2 or 4 ohm and the amp has rms of 500W at 2 ohms and 300W at 4 ohms..thnx

I believe either one will work and you wont notice and audible difference (less then 3dbs).

I don't think that it will make a difference either way in SQ what version your choose. You will have a little bit of additional output if you get the 4 ohm DVC sub and wire it to a 2 ohm load on the amp.
Typically you would choose a 4 ohm load or higher for SQ as opposed to a lower load. In this situation I don't think that it will make a noticeable difference in SQ. So I would just choose the 4 ohm version and get the extra bit of output.

Go with the dual 4 ohm sub, wire it in parallel to 2 ohms. This will deliver max power to the sub, what you choose to do with it and how you use it is far more important. SQ is going to be all about the box and not the impedence of the sub.

For best SQ, I'd choose the 2 ohm version and wire them in series for a 4-ohm load. You will have an inaudible less than 3dB difference in output, but in return you will have maximum damping, maximum efficiency, maximum headroom, and minimum distortion from the amplifier.
For SQ, there IS a difference and the impedance will matter, although, as Rob pointed out, it is FAR more about the enclosure.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
