Gold-plated AGU distribution block with clear cover and five 30 A fuses

The Wires Zone

The Wires Zone AGUDB-3 3-Position AGU Distribution Block 4/8 Gauge with 5×30 A Fuses

SKU CH-FH4B-D9YSX MPN AGUDB-3

Three-position AGU distribution block accepts three 4-gauge inputs and three 8-gauge outputs, includes five 30 A gold-plated fuses, heat-resistant base and clear cover

  • TypeFuse Holders
  • CompatibilityUniversal
  • Three AGU fuse positions distribute power cleanly
  • 4-gauge inputs and 8-gauge outputs handle high current
  • Heat-resistant base and clear cover protect connections
  • Five 30 A gold-plated AGU fuses included
  • Gold-plated contacts resist corrosion for reliable power delivery

3-Position AGU Distribution Block

The Wires Zone AGUDB-3 distributes power from three 4-gauge inputs to three 8-gauge outputs for car audio amplifiers. Gold-plated AGU fuse holders and five included 30 amp fuses protect each circuit. The heat-resistant base and clear cover suit engine-bay or cabin mounting.

Build and daily use

A heat-resistant base withstands under-hood temperatures while the clear protective cover lets you confirm fuse status at a glance. Gold-plated contacts reduce resistance and corrosion over time. Universal compatibility means the block fits standard 4-gauge and 8-gauge power wires without adapters.

Practical limits

Each position is fused at 30 amps, so total continuous draw across all three outputs should not exceed that per circuit. The AGU fuse format limits maximum wire gauge to 4-gauge in and 8-gauge out. Builders needing more than three amplified channels or higher per-channel current will need additional distribution blocks.

Highlights

  • Three AGU fuse positions distribute power cleanly
  • 4-gauge inputs and 8-gauge outputs handle high current
  • Heat-resistant base and clear cover protect connections
  • Five 30 A gold-plated AGU fuses included

Questions about this item

How much current can each AGU fuse in this block handle before it blows?

Each of the five included AGU fuses is rated at 30 amps, so the circuit opens once draw exceeds that level.

What wire gauges do the three input and three output terminals accept?

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

What tools and steps are needed to install the block, and where do installers most often make a mistake?

Strip 4-gauge wire for the inputs and 8-gauge for the outputs, secure each under the set screws, insert the 30-amp AGU fuses, then snap on the clear cover; the step most often missed is fully tightening the set screws before applying power.
