Great stuff for wiring up a marine system. I like the gauge of the wires, how they are shielded and very sturdy. They deliver the power to the speakers well and I have had zero issue with them. I would definitely purchase again. The wires were easy to solder and are color coded black and red. I used nearly the full 100ft spool to wire up 4 8" speakers on a 24 ft Skeeter Sx240. I feel the price was competitive and having delivery to the house is a plus. I didnt have any problems stripping the wires, very easy.

Sturdy and works great

Size: 15ft, Style: 8 Gauge

Used this for an approximately 8' run in my electric UTV to power a 2500W inverter running off the 48V batteries so I could power AC tools out in the field. Very thick casing and nice and strong, but flexible enough to route around the frame of the UTV.
