GS Power 16 Gauge Ga Copper Clad Aluminum CCA Car Audio Video Primary Amplifier Remote Turn on Hook up Trailer Wire | 400 Feet Red & 400 ft Black Combo

I do a lot of electrical work at my shop and I was just blowing through the 100 foot rolls too quickly. These give me a little bit of a breather in between having to buy more. I'll definitely be buying the 400ft rolls from now on.

Great product and a quarter of the price of homedepot.
