YELLOW 12V Auto Primary Wire 18 Gauge 25' ft Car Boat Camper RV Mobile Power Hook Up Cable Specifications: Color: YELLOW Gauge: 18 Length: 25' feet Nice high-quality PVC jacketed single conductor stranded 12 Volt PRIMARY POWER WIRE. Whenever possible we hand roll our wire from a bulk spool in order to save you $$$!!! Popular copper clad wire that's been used for decades hooking up all types of car audio and mobile accessories. This wire is designed for professional installers and does not come with retail packaging or instructions. I have been using this wire for years and it works great. Make sure you get the correct size wire for your needs. Remember the larger the number (gauge) is the thinnest or smaller size wires. 18 gauge is smaller than 16, 16 is smaller than 14, etc. Thinner wire is OK for lower powered applications and short runs. Use thicker wire for higher powered installs and long runs. IMPORTANT! 12 volt vehicle wiring should only be done by qualified technicians. Don't buy if you're not sure what you're doing! Support your local installers. Look in my store for more wire. I have many sizes, lengths, styles, and colors available. Thanks for checking out one of my items. I have been in the wholesale business for over 20 years. Anything you find here will be some of the best deals around. If you don't agree it's pretty simple, I will pay for return shipping so you have nothing to lose. And even give you an extra dollar for your trouble. Quantities are limited and many items are sold out when gone. I appreciate your business! ~Billy D.~
