4M Cable Car Audio Inline Volume Controller for Subwoofer

This wired car audio inline volume controller is designed for vehicle audio gear, giving you direct reach to sound adjustment from a convenient inline control point. As a car audio inline volume controller, it lets you manage the output level of an amplifier or subwoofer without reaching the main universal. The oval inline housing includes a rotary subwoofer volume knob on the front, making level changes simple and accurate during everyday driving. The universal features a black face with a gray outer body, a long black cable, and a transparent connector for a clean, practical wired setup. Used as an amplifier level control, it helps fine-tune bass or system volume to match different songs, road conditions, or listening preferences.
