GR-HL2

Simple Signal Conversion for Clean Audio System Upgrades

The Gravity GR-HL2 2-Channel High to Low RCA Line Converter is designed to allow seamless integration of aftermarket amplifiers into factory car audio systems. It converts speaker-level outputs into low-level RCA signals, enabling connection to subwoofers or external amplifiers without replacing the factory head unit.

This compact converter improves system flexibility by making it easy to upgrade sound quality while maintaining original vehicle audio controls. It ensures stable signal transfer for clearer, more powerful audio performance.

Built-In Remote Turn-On and Noise Isolation Protection

The GR-HL2 includes a built-in 12V remote turn-on output, allowing your amplifier to power on automatically with the vehicle’s audio system. This eliminates the need for additional wiring and simplifies installation.

A built-in ground loop isolator helps reduce unwanted electrical noise such as alternator whine or interference. This ensures cleaner sound output and a more enjoyable listening experience, especially in factory electrical systems.

Adjustable Gain Control for Optimized Sound Tuning

The adjustable attenuation control allows users to fine-tune signal strength for optimal amplifier matching. This ensures proper bass output and balanced audio performance without distortion or signal clipping.

Designed for ease of installation, the GR-HL2 features a compact housing and clear wiring guidance, making it suitable for both beginners and experienced installers. Its 2-channel design is ideal for basic amplifier or subwoofer setups.
