I have 2 subs that can do 125 max rms and I have a rockford fosgate p4002 which can but 100rms x 2 at 4ohm which I want to do but I just want to make sure I am hooking it up right.. Parallel which each other all the positive hooked up together into the positve left side and all the negative plug into the right negative side but that would creat a 2ohm which means I will get more than 200 rms?

That amp should be 2ohm stable. If so then you should be able to run that just fine. I just looked it up...you can run it on a 2ohm load on the RF p4002!! Your fine just turn the gain down a bit. Your just sending a little more power to the subs so adjust the gain accordingly.
