This affordable high power amplifier for cars employs a modern switching PWM power supply to boost the nominal 12V (or 24V for trucks) supply voltage to approximately 33V, enabling the amplifier to deliver higher power levels. Such switched mode power supplies (SMPS) using DC to DC converters help to deliver rock solid bass with a performance that is immune to supply line noise and battery fluctuation. Using FET switching transistors, this unit maintains tightly controlled regulation which results in stable, ripple-free supply voltages. Bipolar transistors are used in the audio output stages as they offer increased output efficiency. The speakers are directly coupled to the outputs to give a clean, powerful bass response. The amplifier will accept low level, ie. speaker outputs from a radio cassette, and line level inputs. This Kit can be used to prevent audible thumps at switch-on.
