Description
Professional-grade fork terminals for negative ground connections and discreet automotive wiring.
Product Overview
The DNA AAC212B fork terminals are gold-plated 12-gauge connectors designed for car audio amplifier installations and automotive electrical applications where reliable, corrosion-resistant connections are critical. Each terminal features gold plating to prevent oxidation and maintain low-resistance contact over time, with black silicone rubber insulators for discreet installations and easy identification of negative/ground connections during complex wiring jobs. The 4mm inner fork width fits standard amplifier and distribution block binding posts, while the 2.3mm cable entry accommodates 12-gauge power and speaker cables. Supplied in a convenient 10-piece pack, these fork terminals are ideal for multi-amplifier installs, audio system upgrades, and professional mobile electronics work where quality connectors prevent voltage drop and signal degradation.

Features & Benefits
Gold Plating for Long-Term Reliability – Prevents oxidation and corrosion that causes poor connections in car audio systems, maintaining low contact resistance even in humid Australian conditions and coastal environments where bare copper terminals fail within months.
Black Insulation for Ground and Negative Connections – Black colour coding makes negative and ground connections instantly recognizable during installation and troubleshooting, following professional wiring conventions where black indicates negative polarity in automotive electrical systems.
Discreet Appearance for Clean Installations – Black terminals blend seamlessly with black power cables and dark engine bay components, creating professional-looking installs that don't draw attention to wiring connections in visible areas like boot-mounted amplifiers.
4mm Fork Width for Standard Amplifier Posts – Precisely sized to fit most car amplifier binding posts and distribution block terminals without excessive play or overtightening that damages the fork, ensuring secure mechanical and electrical connection.
2.3mm Cable Entry for Proper Crimp Fit – Matched to 12-gauge cable diameter for reliable crimp connections using standard automotive crimping tools, eliminating the loose crimps and cable pull-out that occur when using incorrect terminal sizes.
Silicone Rubber Insulation for Heat Resistance – Withstands higher temperatures than PVC insulators without melting or becoming brittle, crucial for terminals near amplifier heat sinks or in engine bay electrical applications where heat is a constant factor.
10-Piece Pack for Complete Installations – Provides sufficient terminals for typical 4-channel amplifier installation (8 terminals) plus spares, or multiple amplifier setups without purchasing excessive quantities that sit unused in the toolbox.
Professional DNA Quality Standards – Manufactured to DNA's car audio specifications ensuring consistent crimp barrel dimensions, proper metal temper for secure fork tension, and reliable performance across thousands of mobile electronics installations.

Frequently Asked Questions
What wire gauge do these terminals fit?
These terminals are designed for 12 AWG (12 gauge) wire, with a 2.3mm cable entry that properly fits 12-gauge automotive and speaker cable for secure crimping.
Will these fit my amplifier terminals?
Yes, the 4mm inner fork width fits most car amplifier binding posts and distribution block terminals, which typically use M4 or 4mm studs for power connections.
Do I need a special tool to crimp these?
Yes, you'll need a standard automotive crimping tool with appropriate jaw sizing for insulated terminals to achieve a secure, gas-tight crimp connection.
Why gold plated instead of regular copper terminals?
Gold plating prevents oxidation and corrosion that degrades electrical connections over time, maintaining low contact resistance for better amplifier performance and preventing connection failures.
Are black terminals only for negative connections?
While black is commonly used for negative/ground connections following professional wiring conventions, you can use black terminals on any connection where discreet appearance is desired.
