Car: Audio Amps

1 Watt Audio Amplifier. 8 Ohms impedance. 20 Hz to 20 kHz. Small, few components.

Schematic for an electronic audio level VU meter that uses LED's to display the volume/audio levels.

This circuit is an alarm for the home, car and a lot more. It employs a magnet and reed switch to trigger the circuit. An intergral piezo sounder produces the alarm sound (100dB). There is also a relay capable fo handling up to 10 amps that will switch wh

This is a RC car project is the transmitter and receiver modules for a Remote Control car, with speed control and continuous steering.

This simple stereo audio amplifier will amplify audio for your low-medium impedance headphones and give you left/right balance control

Flash you car's headlights on/off, either together or alternatively, with this flashing lights electronic circuits. Don't know if it's legal but it's pretty cool :)

This kit uses the TDA2009 class AB audio amplifier IC for high quality stereo applications.

An exciting way to demonstrate the use of alternative energy. It features an aerodynamic sports car shell design with a transparent car body that can be painted or left clear to view the inner mechanics, 4 wheel chassis, powerful 1.4 volt - 350mA solar ce

This audio amplifier electronic circuit uses MOSFET transistors to create more than 25 Watts output power. Uses IRF530 and IRF9530 MOSFET transistors.

Shows an electronic circuit diagram (schematic) for a simple 10 Watt audio amplifier, using only 4 transistors.

Describes the schematic (circuit diagram) and PCB (Printed Circuit Board) for a cheap 100-150 Watt audio amplifier with few components.

Variable gain audio amplifier capable of powering a small speaker for personal use

ElectroKits will soon provide the ultimate in car kits

It's snail-like design may give a lethargic impression but, contrary to first impression, COMET is quick to respond and scurries speedily on command.

Features a telephone ring generators, phone line in-use indicators and an audio interface circuit.

18 Watt Mono Audio Amplifier. Possible to use two for Stereo sound.

An excellent Stereo FM Transmitter which operates through the USB port of essentially any computer. FCC Compliant!

A Mono audio amplifier which produces a very good 7 watts output power.

High quality 25 watt audio amplifier. Combining 2 would give a 50 watt stereo amplifier.

This kit is a great introduction mechanical gear and motor operation.
