Best option available to run power to your trolling motor. Best guage and very tough shielding.

I needed 20' for my old stick steering fiberglass boat for power up front. Bought a 6 position fuse/termination box and mounted it up. Did great...Good wire.

Used this to run from my subs to my amps. And also used it to run my subs in 1ohm setup. Worked like a champ and my system is pumping!!! Will definitely buy again on the next build.
