ok got a us ams md 23 that i am getting ready to sell to a guy i know that has two type r 12s not sure if they are dual 4 or 2 ohm yet my question is the amp does 1000 x 1 at 4ohm mono now if they are dual 4s i can get them wired 4ohm the amp also says it does 500 x2 at 2ohm if they are dual 2s can i wire one to each channel and get a 2ohm load to the amp

If they are dual 4 ohm a series/ parallel configuration will be a 4 ohm load...

your options are:
2 dual 2ohm woofers: .5ohm, 2ohm, 8ohm.
2 dual 4ohm woofers: 1ohm, 4ohm, 16ohm.

if they are dual 2ohm woofers, you series each sub to 4ohms, and run them stereo. or bridge them on the amp at 8ohm. same results.
