digital design m3b red and green led blinking

[FATCHICKS4DAYS]

So I installed a C-MAX 45AH. I have a 240 mechman alternator. I have everything wired up as it should be. I was waiting on my fuses. They came in today I installed them and now my amp LEDs are blinking alternating red and green.

My secondary amp that runs my mids and highs is fine and fully functional. The M3B there is no output.

 

I have power ran from the alternator to the bank as well as a ground from the alternator to the bank and then everything else is connected accordingly. The system was fully functional prior to me installing the fuse block and fuse. I have disconnected every connection one by one I've checked all the fuses I've checked all my connections everything is good and tight and I'm still having this issue does anybody have any pointers or suggestions for me to look because this is above my knowledge base
