what amp is best
 

i have 2 alpine type rs dual 2 ohm 500 rms each i was woundering what amp i should get for them so far i was looking at the alpine mrd m1000 is that a good choice?

Go with the MRP-M1000 its a great fit.
You have two subs that would like to see 500 each.

Wire the subs up to 4ohm each, and wire them to the amp to get a final 2ohm load.
