Stinger SPD512 PRO 0 Gauge T Distribution Block

Stinger SPD512 PRO Series 0GA T-Block Power Distribution Block

A compact 3-port 0GA (1/0 gauge) T-distribution block from the Stinger PRO Series Shoc-Krome corrosion-resistant finish, oversized set screws, deep wire recesses, and daisy-chain design for high-powered multi-amplifier builds.

Product Overview

The Stinger SPD512 is the 0GA (1/0 gauge) version of the PRO Series T-distribution block the largest gauge in the SPD51x T-block range. With three 1/0GA ports, it is suited to high-powered multi-amplifier builds where the main power run is 0GA and needs to be split to two amplifiers, or to daisy-chained configurations in very large systems.

Oversized set screws provide maximum contact and vibration-resistant termination for heavy-gauge wiring. Deep wire recesses eliminate exposed cable for a safe, professional installation.

Features & Benefits

• Three 1/0GA (0 gauge) ports — input and two outputs, or daisy-chain configuration
• Daisy-chain design for flexible multi-block configurations
• Corrosion-resistant Shoc-Krome finish
• Oversized set screws for maximum contact with heavy-gauge wire
• Deep wire recesses — no exposed wire
• Non-fused — suitable for both power and ground side use

Frequently Asked Questions

What is the difference between the SPD512, SPD511, and SPD510?

All three are PRO Series T-distribution blocks with the same Shoc-Krome finish, oversized set screws, and daisy-chain design. The SPD512 is 0GA (1/0GA), the SPD511 is 4GA, and the SPD510 is 8GA. Choose the gauge that matches your main power run.

When do I need a 0GA distribution block?

The SPD512 is suited to systems running 0GA (1/0GA) main power cable — typically high-powered builds rated above 1,500W RMS with large monoblock or multi-amplifier setups driven by the Stinger SK4201 or similar 0GA wiring kit.

Can the SPD512 be daisy-chained?

Yes. Multiple SPD512 blocks can be linked together for very large 0GA distribution systems.

Is this block fused?

No. The SPD512 is a non-fused T-distribution block. The main 0GA power run must be fused with an appropriately rated ANL fuse at the battery — typically 250A for a 0GA run, as provided in the SK4201 kit.

Can this be used for both power and ground?

Yes. The SPD512 can be used on either the positive power or negative ground side of the installation.
