Focal Impulse 4.320 Compact 4/3/2 Channels Class D Amplifier 4 x 55W RMS

Focal Impulse 4.320 Compact 4/3/2 Channels Class D Amplifier 4 x 55W RMS 

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.

Big power from a tiny amp

Focal designed their Impulse 4.320 4-channel amplifier to fit almost anywhere inside a vehicle. The Impulse 4.320 sends 55 watts RMS to each of your speakers from a chassis that's smaller than a brick. You can also use an Impulse 4.320 in 3-channel mode to power a pair of speakers with 55 watts RMS each while sending up to 160 watts to a sub. 

Plays well with other stereos

The Impulse 4.320 comes with input harnesses that let you connect to any aftermarket receiver or a factory radio. Separate filters for the front and rear channels optimize the sound for your speakers and subs. An adjustable phase control on the rear channels comes in handy for tuning a sub's sound to blend in with front speakers.
