3-Position AGU Distribution Block

This gold-plated AGU distribution block provides three fused positions for car audio power wiring. Each position accepts a 4-gauge input and an 8-gauge output, supplying multiple amplifiers from a single main run. A heat-resistant base and clear protective cover shield the fuses and connections. The kit includes five 80 amp AGU fuses ready for installation.

Upgrading from single inline holders

A single inline fuse holder protects only one amplifier feed and leaves the main power wire unfused near the battery. This block consolidates three fused outputs in one location, reducing connection points and voltage drop across the system. The jump is worthwhile when adding a second or third amplifier to an existing 4-gauge main line.

Limits of the AGU fuse standard

AGU glass-tube fuses top out at 80 amps per position, so total continuous draw across the three outputs should stay within that per-fuse rating. The 4-gauge input capacity and 8-gauge output terminals set the practical wire-size ceiling for the block. Installers needing higher per-channel current or larger wire gauges must choose a different fuse format.

Questions about this item

What gauge wires does the AGUDB-3 accept on its input and output terminals?

The block provides three 4-gauge input terminals and three 8-gauge output terminals for power distribution.

How do you install the 80 A AGU fuses into the distribution block without damaging the gold-plated contacts?

Insert each fuse straight into its holder until it seats firmly; do not twist or force the gold-plated ends, and keep the clear cover closed after installation.

When should the included 80 A AGU fuses be replaced after a fault?

Replace any fuse that has blown — indicated by a visible break in the element — with another 80 A AGU fuse before restoring power to the circuit.
