FDA0+4K 0+4 Gauge Dual Amplifier Wiring Kit

The Cadence FDA0+4K is a complete wiring kit for two-amplifier car audio systems, supplying every cable, block, and terminal needed to connect a pair of amps to your vehicle's electrical system. It runs 0 gauge from the battery and splits to 4 gauge at the amplifiers, a layout built for high-current systems up to 3000W.

Power delivery starts with 17' of 0 gauge translucent red soft power cable wrapped in woven nylon mesh, paired with a 3' 0 gauge silver ground. From the nickel-plated ANL distribution block, 6' runs of 4 gauge power and ground feed each amplifier. A nickel-plated 1-way input / 4-way output distribution block and a 1-way input / 2-way output fused block handle the split, with a 150 amp ANL fuse and two 100 amp ANL fuses for protection.

Cadence builds these cables with a braided Super Flex construction that removes trapped air and reduces skin effect. The result is low impedance, cable that stays cool and flexible through tight routing behind seats or along door sills, and less voltage drop between the battery and your amps. Nickel plating on the terminals and blocks resists corrosion in humid climates and on salted winter roads.

The signal side is covered as well: a 17' set of twisted-pair, double-shielded 100% OFC audiophile RCA cables carries head unit output with minimal noise pickup from the power runs. 15' of 12 gauge speaker wire and 16' of 18 gauge remote turn-on wire finish the install, along with ring and spade terminals, butt connectors, cable ties, screws, and a snap-in firewall grommet.

It suits SPL builds, dual-subwoofer setups, and multi-amp component systems in trucks, sedans, and show vehicles.
