Three-Position AGU Distribution Block

This AGUDB-3 block splits a single 4-gauge power feed into three separate 8-gauge outputs. It is designed for car audio installers who need to distribute amplifier power cleanly without running multiple heavy cables from the battery.

Heat-Resistant Base With Clear Cover

The moulded base withstands engine-bay temperatures while the transparent cover lets you inspect every connection at a glance. No active cooling is required and the block draws no power itself, so it adds no electrical load or noise to the system.

Universal Mounting And Crimp-Ready Terminals

Each position accepts standard 4-gauge input and 8-gauge output wires secured by set screws, so no proprietary lugs are needed. The compact three-channel layout fits tight firewall or trunk spaces, though installers must allow room for the cover to swing open for future maintenance.

Questions about this item

How is the AGUDB-3 distribution block mounted, and what step is often missed?

Secure the heat-resistant base with screws through its mounting holes, then snap the clear protective cover on last; installers often forget the cover, leaving fuse connections exposed.

What maintenance does the AGUDB-3 require over time?

Inspect the three AGU fuse holders and all 4-gauge input and 8-gauge output terminals annually for corrosion or loosening; re-torque set screws and replace any discoloured fuses.

What thermal limit appears first during sustained high-current use?

The heat-resistant base is rated to withstand elevated temperatures, but prolonged loads near the 4-gauge wire ampacity will cause the base to soften before the cover or terminals fail.
