I'm looking for some input on the wiring for powering dual Helix 9's (Di & Si) on a stack mount at the bow on a 2017 721 ProXp.
1) How did you guys go about the wiring for power with dual unit set ups?
2) Did you run separate wiring from a fuse block to each unit or tie everything into the existing power at the bow?
I think the existing wiring at the bow that my flush mounted Helix 9 is currently connected to is 10 gauge wiring? I also have a H2 hydrowave currently connected to the power that the existing sonar unit is connected to.
Any thoughts and input greatly appreciated.
