Focal IMPULSE 4.320 – Compact 4-channel digital amplifier
With the Impulse 4.320 amplifier, breathe new life into your car radio. The amplifier of a car radio (standard equipment or purchased subsequently) very quickly admits its limits in terms of power and dynamism. At high sound levels, it quickly goes into saturation and spoils the musical pleasure. To compensate for this lack and allow your speakers to express themselves fully, the Impulse 4.320 is the ideal solution. It will boost your installation without the need for complicated assembly. Semi “Plug and play”, the Impulse 4.320 is a 4-channel digital micro amp, delivering 4 x 55 Watts. The Impulse 4.320 perfectly complements the Focal Integration speakers.
