Why is the sound level so low on my Blaupunkt PA2150 Car Amplifier?

If you're experiencing a very low sound level with your Blaupunkt Car Amplifier, first verify that the radio's balance and fader controls are at the center positions. Then, check the amplifier’s input gain control setting and adjust it for higher output levels if necessary, setting the gain closer to 0.3 volts. If the receiver has very low output voltage levels, you might need to use a step-up 'line driver'.
