I have two Tsunami DB-1100D (1100 watts @ 1ohm) amps coming in along with a DB-4440 (75x4).
I already have a 2 gauge wire going to the back from my previous setup, I know the power/fusing was low, so I bought an Optima Yellow top and a 300amp fuse for under the hood. Is that 2ga. wire gonna be big enough for 2.5kw?
Also, my distribution block has 60 amp fuses, do I need to get bigger fuses there? I don't think they go much higher in the glass type.
