EHOPHNA Car Amplifier Bass Volume Control Knob 12.7ft Copper Cable

Description

Product Overview

The EHOPHNA Car Amplifier Bass Volume Control Knob is engineered to eliminate the common mismatch between a vehicle’s main audio control board and subwoofer volume. Featuring a 12.7‑foot pure copper core cable with high‑quality PVC insulation, the kit delivers a stable, low‑loss signal path. The three‑pin crystal connector plugs directly into the subwoofer’s sound interface, while the knob end fits the existing control panel. An integrated power‑indicator LED confirms proper connection, giving you confidence before you hit the road.

Install the extension cable in a convenient location—under the dash, near the driver’s seat, or in the trunk—to keep the knob within easy reach. Whether you’re cruising city streets or navigating highways, the knob lets you fine‑tune low‑frequency output without distracting adjustments.
