Any good. Alpine MPR F600? I guess it's a little too late for this question since i already purchased it to push 4 Polk components. I think it's MPR, it may be MRP. I am not looking at the sales invoice now. Let me know how this should work. It pushes 100 RMS X4.

 

It will work fine and will be better than anything that came in the car from the factory. Just be sure to run proper power and ground wires and get the connections right.
