This Powersports/Marine amp kit features the best quality copper wire available for maximum current delivery and strict adherence to American Wire Gauge standards. Add to that our use of pure oxygen free copper flux-tinned conductors and braided sleeving that deliver excellent corrosion resistance and installation reliability and you have the foundation for an exceptional audio power product. These powersports/marine amp kits are topped off with a unique waterproof mini-ANL fuse block design with EZ-insert terminals, high-temp construction, and machined brass inserts that affords convenient access along with installation security.  *The amp power kits come complete with all the cabling, speaker wires, terminals, disconnects, and fuse blocks needed to perform a quality installation, except for RCA interconnects. Since we offer various levels of high performance RCA interconnects for aftermarket radios and high-level input for OEM upgrades, we leave it up to the consumer/dealer to make the RCA choice.
