4. FILTERING, RECOMMENDED AMPLIFIER SETTINGS

The correct choice of amplifier, its settings, filtering and enclosure largely influence on the lifespan of your audio system. You should select an amplifier with a nominal power, not exceeding the nominal power of the speakers. Proper coordination of the head unit (HU) with the amplifier will allow to get a clean, undistorted signal applied to the component to prevent overheating and voice coil damage. Recommended settings of the amplifier and HU: Volume of HU should not exceed 80%. The amplifier sensitivity should be set to 50%.

The recommended filter settings:
The high pass filter HPF (the filter that cuts all frequencies below those set for the filter) should be set to 150-250 Hz (24 dB/Oct), or 250-350 Hz (12 dB/Oct)
The low pass filter LPF (the filter that cuts all frequencies above those set for the filter) should be set to 8-12 kHz (12 dB/Oct)

Recommended amplifiers: AAB- 1200.2D, AAB- 1800.2D, AAP-500.2D, AAP-800.2D, AAP-400.4D.
