JL Audio Master ANL Fuse Block (XB-MFBU-ANL) - 010-13727-00 (91656)

JL Audio XB-MFBU-ANL Master ANL Fuse Block is a heavy-duty master fuse block engineered to protect the main power wire feeding multiple amplifiers or an entire system. Each wire connection block can rotate to several different entry angles, giving you flexible routing options when working with large-gauge power wire in tight engine or battery compartments.

OmniSert™ captured-wire receptacles accept a wide range of cable sizes from 4 AWG up to 1/0 AWG without separate adapter sleeves. The block is built from forged and machined brass with marine-grade plating, and uses a high-temperature polycarbonate base and cover to provide insulation and protection in demanding automotive and marine environments.
