Can't remove the original source on your car? In order to provide your amplifiers with a quality signal and benefit from the full performance of your Focal installation, while retaining your original car radio and controls, choose the HILO.V3 converter. HILO.V3 converts an amplified signal into a low-level stereo output, eliminates spurious interference and introduces full mass separation. You can therefore use a power amplifier with ease, eliminating interference. It becomes easy to create a quality hi-fi installation in your vehicle. Selectable DC and AC detection makes the HILO compatible with all manufacturers' original sources.
