i am going to be powering four jl audio w3d4 subwoofers. the amp i was looking at is the alpine mrp-m2000, but if there is anything else you all would recommend, it would be greatly appreciated. if you all know if that is the right amount of power, or if there is an amp that will do better for a cheaper price tag, that's great too. i will be running at a 2 ohm load.
