Add A Sub Bass Amplifier Adapter Interface w/Amp Remote Turn On Wire

In this review the reviewer looks at an Add A Sub bass amplifier adapter designed to simplify adding a powered sub to select GM and GMC vehicles without factory premium amps. The bottom line: this adapter is for DIY installers and professional installers who want a clean, noninvasive connection at the back of the factory radio to get RCA outputs and a remote turn on without cutting or splicing into factory wiring, making the installation faster and less error prone.

Key Features

• Plug and play connection: Connects at the back of the factory radio so installers do not need to splice factory wiring, reducing installation time and risk of wiring mistakes.
• RCA outputs: Provides line-level RCA outputs so the new amplifier gets a proper input signal for cleaner bass reproduction compared with speaker-level tapping.
• Remote turn on wire: Supplies a power wire for the amp remote turn on connection so the amplifier powers up and down with the factory radio.
• Adjustable gain output: Built-in gain adjustment helps match output level to the aftermarket amplifier for better integration and lower noise.
• Vehicle compatibility checked: Made specifically for 7 in factory radio models of Chevrolet and GMC trucks and cars from listed years to ensure the connector pinout matches.

Who It's For

This adapter is best for owners of compatible Chevrolet and GMC models with the 7 in factory radio who want to add a powered subwoofer without modifying factory harnesses. It suits DIY audio enthusiasts and installers who prefer a neat, reversible install and need RCA outputs and a remote turn on lead.

It is not for vehicles that already have a factory premium amplified system such as Bose or other branded amps; those systems are incompatible and require different interfaces or tapping methods, so owners of factory amplified stereos should look elsewhere.

• RCA outputs and remote turn on wire provide the connections needed for a clean aftermarket amp install.
