Amp wire size

Hi all so I'm trying to decide whether to run a new power cable for my amps I am changing my system up currently I have a jl 700/5 xd. I am going to keep this and only use the speaker channels which are powering my front speakers that I have set up as active. I am not going to use the sub channel. I plan to add in a ct sounds ct1000.1d amp to run two ct sounds meso 6.5 subs. I also have a jl audio fix 82 and jl twk 88.

Currently I have a 4 gauge ofc run for power about 13 ft or so.

I assume my jl amp will only use 300 probably less rms because I am not running the sub. If this is correct and the subs only wanting 400 rms each my system should be around 1100 rms.

By the charts I can find I should be ok with my wire I Currently have for power. Or should I run a bigger power wire say a 2 gauge? I don't have alot of knowledge on car audio so if anyone with more experience could please let me know if my assumptions are correct or if I should just upgrade the power and ground it would be much appreciated thanks.
