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.
The technology used for Impulse 4.320 was inspired by the Performance range‚Äôs FD amplifiers.
With an efficiency of more than 90%, Class D amplification has numerous advantages: less heat, low power consumption, low distortion at high volumes, compact… With the Impulse 4.320 amplifier, an unbeatable size/power ratio has been achieved. It delivers 4 x 55 or 2 x 160 Watts RMS at 4 Ohms.
Thanks to the adequate power and the fast attack for realistic and more aerated sound, it will completely transform the sound of your front and rear speaker drivers.
Impulse 4.320 – Cables Measuring only 67/8 x 17/8 x 25/8″ (17.65 x 4.6 x 6.7 cm) Impulse 4.320 can easily be concealed within the dashboard or the centre console.
Equipped with high-level (automatic detection feature) and low-level inputs, it is compatible with all head units. Supplied with all fastenings, an adaptor for the head unit‚Äôs speaker driver outputs, RCA adaptors for aftermarket head units and power connector, this amp was specially designed to be easy to install. No direct hook up to the vehicle‚Äôs battery is required.
An optional ISO connector is available for ‚ÄúPlug&Play” connectivity via the head unit‚Äôs harness.

To ensure compatibility with different head units, this amplifier features a 2-channel or 4-channel input selector switch.
Most of all, Impulse 4.320 has been designed to power front and rear speaker drivers. However, it can also be used in a 3-channel or 2-channel mode in order to meet all needs for improving small installations and it can also be used for powering the front speaker drivers and a small subwoofer.
Each pair of channels features an active crossover to adapt the sonic response according to the speaker drivers used. The front channels can be used for wideband speaker drivers or the high-pass filter can be used for frequencies above 75 Hz when only small speaker drivers are used. By avoiding having small speaker drivers reproduce very low frequencies, the sound will have more clarity. The rear channels are equipped with an active crossover (wideband, high-pass or low-pass) and with progressive phase adjustment for powering a small subwoofer or wideband speaker drivers of different sizes.
