The Bass Rockers HLC100 High/Low Level Converter is designed for car audio enthusiasts who want to upgrade their sound system without replacing their factory radio. Many OEM and basic aftermarket head units only offer speaker-level outputs, which cannot be connected directly to most amplifiers or powered subwoofers. The HLC100 solves this problem by safely converting those high-level speaker signals into low-level RCA signals, giving you the flexibility to add more power and better sound. This 2-channel line output converter features independent adjustable output levels for the left and right channels. By dialing in the correct level, you can better match your amplifier's input sensitivity, reduce the risk of distortion, and maintain a cleaner audio signal path. This makes it especially useful when integrating amplifiers with factory stereos that are tuned differently from aftermarket head units. To help preserve audio quality and durability, the HLC100 is built with gold-plated RCA connectors. These connectors are more resistant to corrosion and provide a more reliable interface between your converter and amplifier. Whether you're adding a dedicated subwoofer amplifier or boosting your front and rear speakers, the HLC100 provides a stable connection point in your system. Installation is made simple with a compact housing and multiple mounting options. The unit includes pre-installed double-sided tape for quick, tool-free mounting, as well as two screws for a more permanent installation. Its small footprint allows it to fit behind dashboards, under seats, or near amplifiers in the trunk. Whether you're upgrading a daily driver or building a budget-friendly audio setup, the Bass Rockers HLC100 is a practical and efficient way to integrate amplifiers and subwoofers with radios that only provide speaker-level outputs without the need for a full head-unit replacement.
