Article description

Give your head unit a breath of fresh air. Head unit amplifiers (whether OEM or aftermarket) soon reveal their limits in terms of power and dynamics. At high volume, they soon saturate and ruin the listening pleasure. To compensate for this and to enable you to get the best out of your speaker drivers, Impulse 4.320 is the ideal solution. It will give your installation a boost without you having to embark on a difficult installation process.

Semi “Plug&Play”, Impulse 4.320 is a miniature 4-channel digital amplifier delivering 4 x 55 Watts.

Impulse 4.320 is the perfect complement for your Focal Integration speaker drivers.
