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: 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: A dedicated 4 gauge output provides a convenient secondary ground tap-off for smaller circuits, chassis grounds, or accessory equipment
  • Shock-Krome plating: 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: 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: Purpose-built for the negative battery post, providing a clean and organised negative distribution point for complex 12V builds
