Description
Stinger SPD8120 PRO Series AGU Fused Distribution Block 4GA Input and Two Fused 8GA Outputs with Shoc-Krome Finish and Acrylic Cover
The SPD8120 from Stinger is a PRO Series AGU fused distribution block accepting one 4GA input and distributing to two individually fused 8GA outputs. Each output has its own AGU fuse position for independent amplifier protection, accepting AGU fuses from 5A to 60A. The Shoc-Krome chrome plating resists corrosion, oversized set screws provide secure termination, and the screen-printed snap-off top cover allows visual fuse inspection without tools. Fuses are not included.
Product overview
The SPD8120 combines 4GA to 8GA power distribution and per-output AGU fuse protection in a single compact unit, removing the need for separate inline fuse holders for each amplifier output. One 4GA input feeds two fused 8GA outputs, each with its own AGU fuse position rated from 5A to 60A, providing individual protection per amplifier or accessory circuit. The clear acrylic high-temperature base and snap-off top cover allow fuse inspection and replacement by hand without requiring tools.
The Shoc-Krome corrosion-resistant plating and oversized set screws ensure reliable long-term performance, while the deep wire recesses prevent exposed wire at the termination points for a clean, professional installation result. The compact design minimises installation footprint and is suited to installations where space around the distribution point is limited.
Features and benefits
One 4GA input, two individually fused 8GA outputs: A single 4GA input distributes to two 8GA outputs each with its own AGU fuse position, providing individual circuit protection per output 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.
Shoc-Krome corrosion-resistant plating: The Shoc-Krome chrome plating provides corrosion resistance and a premium appearance consistent with the Stinger PRO series range.
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 minimises installation footprint, suited to installations where space around the distribution point is limited.
Suitable for positive or negative distribution: The SPD8120 can be used on either the power or ground side of the installation, providing flexibility in layout and configuration.

Frequently asked questions
What is an AGU fuse?
An AGU fuse is a glass tube fuse in a cylindrical format, typically rated from 5A to 60A. AGU fuses are widely used in car audio for protecting lower to mid-powered amplifier power connections and are a different format from ANL fuses used in higher-current 0 gauge installations.
What is the difference between the SPD8120 and the SHD820?
Both are fused distribution blocks with one input and two fused outputs. The SPD8120 uses AGU fuses rated from 5A to 60A and connects a 4GA input to two 8GA outputs, suited to lower-powered builds. The SHD820 uses MIDI fuses and connects a 0 or 4GA input to two 4 or 8GA outputs, suited to higher-powered builds requiring greater fuse current capacity.
Are AGU fuses included with the SPD8120?
No. AGU fuses are not included and must be purchased separately. Select the fuse amperage rating appropriate to each connected amplifier, which will be 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 SPD8120 be used for ground distribution as well as power?
Yes. The SPD8120 can be used on either the positive power or negative ground side of the installation, providing flexibility in layout and ground distribution configuration.
