JL Audio XD-MFBW-MAXI Water-Resistant Master MAXI™ Fuse Block is a compact, marine-grade master fuse block designed to protect the main power cable feeding your amplifier or distribution system. It uses a genuine MAXI™ blade fuse and accepts a wide range of cable sizes, making it ideal for high-current automotive and marine audio installs.
OmniSert™ captured-wire receptacles allow secure terminations from 8 AWG up to 4 AWG power wire without separate adapter sleeves. Forged and machined brass construction with marine-grade plating ensures excellent conductivity and long-term corrosion resistance, while the high-temperature polycarbonate base and hinged cover provide insulation and protection in harsh environments.
