JL Audio XD-BPW4-100 Power Wire — 4 AWG, 100 ft (Black) is a bulk spool of true-spec 4 AWG power cable designed for medium-to-high current 12 V distribution in automotive, marine, and powersports systems. The 100 ft (30.48 m) continuous length makes it ideal for custom wiring, marine rack/helm installations, and fleet or shop harness production where consistent conductor characteristics matter.
JL uses pure oxygen-free copper (OFC) conductors to minimize voltage drop and support clean current delivery under sustained amplifier or subsystem load. The flexible black PVC outer jacket provides negative/return polarity designation and allows clean routing through conduits, bulkheads, dash passages, and amp rack harness paths.
