Power Distribution Block for Car Audio

The Wires Zone CDB4-48 distributes a single 4-gauge power or ground cable into four 8-gauge outputs. Its nickel-plated contacts and heat-resistant base suit car-audio installers who need clean, reliable power splitting for multiple amplifiers or accessories. The clear protective cover allows visual inspection of connections.

Suits single-feed multi-amp builds.

Installers running several amplifiers from one main power line will find the four 8-gauge outputs convenient. Builders whose main feed is larger than 4-gauge, or who require more than four output connections, should look at a different distribution solution.

48-model designation

The CDB4-48 model number identifies this specific 4-gauge-to-8-gauge configuration. Matching the model ensures the correct input and output gauge combination for the planned wiring layout.

Questions about this item

What wire gauges does the CDB4-48 distribution block accept?

The block accepts one 4-gauge input and splits it to four 8-gauge outputs for power or ground distribution.

What mounting space does the heat-resistant base require?

The base is designed for universal fitment in standard automotive installation locations; allow clearance for the clear protective cover over the terminals.

How is the CDB4-48 wired and what step is often missed?

Insert the 4-gauge supply into the single input terminal, then connect up to four 8-gauge leads to the output terminals; the step often missed is snapping the clear protective cover back on after tightening all set screws.
