Gravity 3-Pin Quick Release Power Coupler for Car Audio Amplifiers & Active Subwoofers (80A Heavy-Duty Terminal Block)

Product Overview

Easily disconnect and remove your car audio amplifier or powered subwoofer enclosure in seconds without tools using the Gravity 3-Pin Quick Release Power Coupler. Designed specifically for automotive sound systems, this heavy-duty 3-terminal disconnect block safely consolidates your Positive (+12V), Remote Turn-On (REM), and Ground (GND) power cables into a single plug-and-play connection.

Constructed from high-temperature, heat-resistant industrial polymer and equipped with heavy-duty high-conductivity metal pins and set screws, the Gravity Quick Release Coupler supports up to an 80-Amp power rating. Whether you need to free up trunk space for luggage, service your audio setup, or prevent battery drain, its secure polarized interlocking housing ensures zero accidental short circuits and maximum electrical conductivity.

Key Features & Performance Highlights

• 3-Pin All-in-One Power Integration: Features dedicated clearly labeled terminals for Positive (P+), Remote (REM),and Ground (GND) wiring on both Power and Amplifier sides.

• High 80A Current Rating: Engineered to handle high-current audio demands up to 80 Amps without voltage drop or overheating.

• Heavy-Duty High-Conductivity Metal Contacts: Corrosion-resistant nickel/silver-finish solid metal pins and allen set-screw terminals ensure clean, uninterrupted power transfer to amplifiers and active subwoofers.

• Heat-Resistant Polymer Housing: Rugged, high-temperature molded body prevents melting or warping under demanding automotive cabin and trunk conditions.

• Screw-Mountable & Polarized Safety Design: Keyed interlock alignment prevents reverse-polarity connection mistakes, while integrated set-screw terminals firmly clamp bare power wires without crimping.

• Compact & Space-Saving Footprint: Ultra-compact dimensions (1.6" x 1.9" x 0.6") allow clean installation behind seats, under carpets, or next to subwoofer enclosures.

Frequently Asked Questions (FAQs)

1. What wires connect to the Gravity 3-Pin Quick Release Coupler?

It features three clearly marked screw terminals on each half: P+ (12V Main Power), REM (Remote Turn-On wire), and GND(Chassis Ground), allowing complete power disconnection in one pull.

2. How much amplifier power can this coupler handle?

Rated up to 80 Amps continuous current, it safely supports mono amplifiers, 4-channel amplifiers, 5-channel amplifiers,and powered active subwoofer enclosures up to ~800W–1000W RMS.

3. Can I plug it in backwards by mistake?

No. The male and female housings feature a polarized center alignment key and offset pin sizing (thicker pins for Power/Ground and a thinner center pin for Remote), making reverse-polarity connection impossible.

4. What is included in the package?

The box includes 1 x Gravity 3-Pin Quick Release Power Coupler Set (1 Power Side Half + 1 Amplifier Side Half).
