Stinger SPD8124 2 4GA In 4 8GA Out Gold AGU Fused Distribution Block

Stinger SPD8124 PRO Series AGU Fused Distribution Block 2x4GA Inputs and Four Individually Fused 8GA Outputs with Acrylic Cover

The SPD8124 from Stinger is a PRO Series AGU fused distribution block accepting two 4GA inputs and distributing to four individually fused 8GA outputs. Each output has its own AGU fuse position for independent per-amplifier protection, accepting AGU fuses from 5A to 60A. The screen-printed snap-off top cover allows visual fuse inspection without tools, oversized set screws provide secure termination, and deep wire recesses prevent exposed wire. Fuses are not included.

Product overview

The SPD8124 is the 4-output counterpart to the SPD8120 in the Stinger PRO Series AGU fused distribution block range, designed for larger multi-amplifier car audio builds requiring individual fuse protection for up to four amplifiers from a single distribution point. Two 4GA inputs feed four individually fused 8GA outputs, each with its own AGU fuse position rated from 5A to 60A, providing independent protection per amplifier circuit without requiring four separate inline fuse holders.

The clear acrylic high-temperature base and snap-off top cover allow fuse inspection and replacement by hand without requiring tools. Oversized set screws maximise contact at each termination point, and deep wire recesses prevent exposed wire for a clean, professional installation result. The compact design minimises installation footprint and is suited to installations where multiple amplifier power and fuse connections need to be consolidated at a single point.

Features and benefits

Two 4GA inputs, four individually fused 8GA outputs: Two 4GA inputs distribute to four 8GA outputs each with its own AGU fuse position, providing individual circuit protection per output for up to four amplifiers without requiring separate inline fuse holders.

AGU fuse compatibility from 5A to 60A: Accepts standard AGU fuses across the full 5A to 60A range, covering the circuit protection requirements for a wide range of lower to mid-powered amplifier installations.

Snap-off top cover for tool-free fuse inspection: The screen-printed snap-off top cover removes by hand for quick visual fuse inspection and replacement without requiring any tools.

Oversized set screws and deep wire recesses: Oversized set screws maximise contact at each termination point, and deep wire recesses prevent exposed wire for a clean, professional installation result.

Clear acrylic high-temperature base: The high-temperature rated clear acrylic base provides durability in demanding installation environments and maintains visibility of the internal connections.

Compact space-saving design: The compact form factor consolidates two inputs and four fused outputs in a single unit, minimising installation footprint compared to using multiple separate fuse holders.

Suitable for positive or negative distribution: The SPD8124 can be used on either the power or ground side of the installation, providing flexibility in layout and configuration.

Frequently asked questions

What is the difference between the SPD8124 and the SPD8120?
Both are PRO Series AGU fused distribution blocks with identical AGU fuse compatibility, clear acrylic cover, and set screw termination. The SPD8120 has one 4GA input and two fused 8GA outputs, suited to two-amplifier builds. The SPD8124 has two 4GA inputs and four fused 8GA outputs, suited to four-amplifier builds requiring greater distribution capacity.

What is the difference between the SPD8124 and the SHD821?
Both are 2-input, 4-output fused distribution blocks. The SPD8124 uses AGU fuses rated from 5A to 60A for 4GA to 8GA wiring, suited to lower-powered builds. The SHD821 uses MIDI fuses for higher-current 0 or 4GA to 4 or 8GA wiring, suited to higher-powered builds requiring greater fuse current capacity.

Are AGU fuses included with the SPD8124?
No. AGU fuses are not included and must be purchased separately. Select the fuse amperage rating appropriate to each connected amplifier as stated in the amplifier's installation manual. Contact us if you need guidance on correct fuse selection.

Can the fuses be inspected without removing the block from the installation?
Yes. The screen-printed snap-off top cover removes by hand without tools, allowing visual fuse inspection and replacement in place without disturbing the installation.

Can the SPD8124 be used for ground distribution as well as power?
Yes. The SPD8124 can be used on either the positive power or negative ground side of the installation, providing flexibility in layout and ground distribution configuration.
