Stinger SPT53303 Negative Battery Terminal With Dual 5/16" Ring
High-Power Negative Battery Terminal Dual 5/16″ Ring, 0GA & 4GA Outputs, Shock-Krome Finish.
Product Overview
The Stinger SPT53303 is a PRO-series negative battery terminal designed to provide a high-power ground connection point at the battery for serious car audio and 12V power builds. Featuring dual 5/16″ ring terminal acceptance alongside two 0 gauge outputs and one 4 gauge output, the SPT53303 gives installers maximum flexibility for heavy-gauge ground cabling and ring terminal connections at the battery negative post.
Finished in Stinger's corrosion-resistant Shock-Krome chrome plating and fitted with oversized set screws for a secure mechanical hold, the SPT53303 is built to handle the demands of high-current audio installations where a clean, reliable negative connection is critical. Whether you're running multiple amplifier grounds to the battery or building a custom dual battery setup, this terminal provides the connection capacity and build quality to do it properly.
Key Specifications
- Terminal polarity: Negative
- Dual 5/16″ ring terminal acceptance: Yes
- Output configuration: (2) 0 gauge outputs + (1) 4 gauge output
- Finish: Chrome (Shock-Krome plating)
- Connection: Oversized set screws
- Corrosion resistant: Yes Shock-Krome plating
- Brand: Stinger
- SKU: SPT53303
Features & Benefits
- Dual 5/16″ ring terminal acceptance: Accepts two 5/16″ ring terminals simultaneously, providing additional ground connection points for amplifiers, chassis grounds, or accessory circuits without ring terminal adapters
- Two 0 gauge outputs:Â Dual 0 gauge wire outputs allow multiple heavy main ground runs directly from the negative battery terminal, ideal for high-current audio builds with multiple amplifiers
- One 4 gauge output:Â A dedicated 4 gauge output provides a convenient secondary ground tap-off for smaller circuits, chassis grounds, or accessory equipment
- Shock-Krome plating:Â Stinger's corrosion-resistant chrome finish withstands the heat, moisture, and chemical exposure of an automotive engine bay, maintaining reliable contact and a premium appearance
- Oversized set screws:Â Large set screws ensure a tight, secure mechanical connection on all wire outputs, reducing the risk of ground connection failure under vibration
- Negative terminal specific:Â Purpose-built for the negative battery post, providing a clean and organised negative distribution point for complex 12V builds
