KnuKonceptz KCA Amp Installation Kits feature oversized Copper Clad Aluminum (CCA) conductors, exceeding American Wire Gauge specifications for the specified gauge. Kit Includes - 18 Ft Ultra Flex Blue Battery Wire, 5 Ft Ultra Flex Black Battery Ground Wire, one In Line ANL Fuse Holder with 250A Fuse, one 16 Ft Two Channel Twisted Pair RCA Cable, Remote Turn One Wire, 1/0 Gauge Ring Terminals, Grommet and Firewall Bushing. You’re Grounded - We include a healthy amount of ground wire. When adding a large system, we recommend a short battery to chassis ground to upgrade the factory grounds too! Rated in Amps, Not Watts - KnuKonceptz uses your amplifier's fuse rating to calculate the proper gauge wire for your installation. Refer to your amp's fuse rating in the manual or if available, add up the total fuses on board your amplifier. If your total system is under 250A, this kit will safely power your installation.
