Stinger SPT8148 4 Pack 8GA 1/4" Spade Terminals

Stinger SPT8148 Gold-Plated Brass 8 Gauge Barrier Spade Terminal 4 Pack with 2 Red and 2 Black for 1/4 Inch Stud Connections

The SPT8148 from Stinger is a 4-pack of gold-plated brass barrier spade terminals for 8 gauge cable with a 1/4 inch stud diameter connection, supplied as 2 red terminals for positive connections and 2 black terminals for negative connections. The gold-plated brass construction combines corrosion resistance with low resistivity and mechanical strength suited to car audio amplifier and 12V automotive accessory installations.

Product overview

Brass provides a combination of mechanical strength and low electrical resistivity that makes it well suited to automotive electrical connections, maintaining reliable contact under the vibration and temperature cycling found in vehicle environments while minimising voltage drops that can introduce distortion in audio signal chains. The gold plating on each terminal resists corrosion and oxidation over time, maintaining a clean contact surface and further reducing contact resistance at each connection point.

The 1/4 inch stud diameter suits the standard spade terminal connections found on amplifiers, distribution blocks, fuse holders, and other common 12V audio components. Two red and two black terminals are included per pack, covering both positive and negative applications in a single purchase without requiring separate colour packs. The barrier spade design allows quick, secure connections that can be connected and disconnected without tools, suited to both permanent installations and service-friendly builds.

Features and benefits

Gold-plated brass construction: Brass provides excellent vibration resistance and mechanical strength, while the gold plating resists corrosion and oxidation and minimises contact resistance at each connection point for long-term reliability in car audio installations.

8 gauge compatibility: Designed for 8 gauge power and ground cabling, suited to mid-powered car audio amplifier installations and 12V accessory circuits using 8 gauge wire.

1/4 inch stud diameter: Suits standard 1/4 inch spade terminal connections used on amplifiers, distribution blocks, fuse holders, and other common 12V audio and accessory components.

4-pack with 2 red and 2 black terminals: Two red terminals for positive connections and two black terminals for negative connections, covering both polarities in a single purchase.

Barrier spade design: The barrier design covers the crimp end of the terminal for a cleaner, safer termination, and the spade format allows quick connection and disconnection without tools.

Frequently asked questions

Why are the SPT8148 terminals made from brass rather than copper or aluminium?
Brass offers a combination of mechanical strength and low electrical resistivity suited to automotive connections. It maintains reliable contact under vibration and temperature cycling in vehicle environments, while its low resistivity minimises voltage drops and potential audio signal distortion at connection points. The gold plating adds corrosion resistance and further reduces contact resistance over the long term.

What does the gold plating do?
The gold plating resists corrosion and oxidation over time, maintaining a clean contact surface at each connection point. It also further reduces contact resistance compared to unplated or tin-plated terminals, contributing to long-term connection reliability in car audio installations.

What is the difference between the SPT8148 and the SPT5148?
Both are 8 gauge spade terminal 4-packs with 2 red and 2 black terminals. The SPT5148 is a PRO series chrome finish fork spade terminal with a number 10 fork hole. The SPT8148 is a gold-plated brass barrier spade terminal with a 1/4 inch stud diameter. The SPT8148 suits 1/4 inch stud connection points on amplifiers, distribution blocks, and fuse holders, while the SPT5148 suits number 10 screw and stud connection points. Confirm the stud size at your specific connection point before selecting between the two.

How many terminals are included in the SPT8148 pack?
The SPT8148 contains four terminals per pack: two red for positive connections and two black for negative connections, covering both polarities in a single purchase.

What stud size do the SPT8148 spade terminals fit?
The SPT8148 fits standard 1/4 inch (6mm) stud diameter spade connections found on amplifiers, distribution blocks, fuse holders, and other common 12V audio and accessory components.
