The mini car subwoofer output 22W into 4 ohm amplifier, Variable Low Pass Frequency: 70 – 150Hz

This unit should be connected to an amplifier of the car audio using the often-needed additional “punch” to music by a subwoofer. Since the very low frequencies are spherical, an amplifier needs to lead this special speaker. The used power amplifier is a good and inexpensive BTL (Bridge Amplifier) 13-pin IC from Philips (now NXP Semiconductors) were prepared to offer a very small number of parts and can be 22W at 4 ohm load on the battery voltage of 14.4 V production car audio.
