Show original supplier description
The KnuKonceptz KCA Complete 4 Gauge Amplifier Installation Wiring Kit provides essential components for a robust car audio setup. This kit features 18 feet of 4 gauge Ultra Flex RED KCA Power Wire and 3 feet of 4 Gauge Ultra Flex Black KCA Ground Wire, ensuring adequate length for most installations. This kit also includes an inline fuse holder with an 80A AGU Fuse for circuit protection. For audio signal transmission, it comes with a 17 foot Bassik Twisted Pair RCA Cable constructed from Oxygen Free Copper (OFC). Music is then guided to your speakers by 20 feet of 14 Gauge Bassik Black Speaker Wire. KnuKonceptz emphasizes quality and value, utilizing Copper Clad Aluminum (CCA) in their KCA series cables. While CCA is less conductive than Oxygen Free Copper (OFC), KnuKonceptz compensates by increasing the conductor size to achieve similar performance at a lower cost. The ultra-flexible PVC jacket is resistant to grease, oil, and extreme temperatures (-40 to 105 C), ensuring durability. The kit also includes necessary hardware such as battery and speaker terminals, a firewall grommet, and a bushing.
