JL Audio 3-Way Power Distribution Block (XD-PDBU-3X) - 010-13457-00 (90364)

JL Audio XD-PDBU-3X 3-Way Power Distribution Block is an unfused power distribution block engineered to split a single high-current power feed into three smaller branch circuits. It is designed for multi-amp automotive, marine, and powersports audio systems where clean, centralized power routing is required without adding fuse redundancy at the distribution point.

The block accepts large input cable from 1/0 to 4 AWG and distributes to three output runs that accept 4 AWG to 8 AWG wire. JL’s OmniSert™ captured-wire receptacles allow secure terminations across mixed gauges without needing additional reducers or sleeves. Forged and machined brass internals with marine-grade plating deliver excellent conductivity and corrosion resistance, while a high-temperature polycarbonate cover provides insulation and protection.
