A distribution block acts as the "nerve center" of your amplifier installation — a single power wire runs from your battery to the block, with smaller wires branching off to your various components. It's a more efficient way to run your wiring, and it also makes it easier to troubleshoot problems.

This FBXS20 distribution block can handle up to two 1/0-gauge inputs and two 1/0-gauge outputs, which makes it perfect for special application systems — such as in a boat or RV — where a single-cable hookup might not be what you need. In your car, you can run power straight from your battery to the block to deliver two lines of clean, protected power to both your full-range and subwoofer amps.

StreetWires machines their fused distribution blocks from solid brass, then coats them with corrosion-resistant, Diamond Plate Nickel for outstanding current delivery and low power loss. Clear, impact-resistant quick-release covers allow easy access to fuses, while steel spring-clips make sure your fuses always maintain solid contact. Your power cables stay secure in deep socket compression-screw terminals. Warranty: lifetime.
