Need help installing my new system

I've got a Rockford Fosgate 501BD and a JBL CS 60.4. I had it wired with #4 power wire in my last car with no troubles but I have a feeling it should have been something bigger. I'm thinking I should have #2, what do you guys think?

You only have a 90amp (RF=50 & JBL=40) draw so 4ga (good for up to 125a)will be more than enough. Just make sure you have a 100amp fuse near the battery and you are good to go. Do you have the Rockford fused as it says it is 50a fused externally? Not 100% sure on this but I believe you need a 50amp fuse right before the power wire goes into it. If you have a fused distro that would work.
