12V Car Audio amplifier circuit, 50W - 65W with PCB ...

    https://www.eleccircuit.com/12v-car-audio-amplifier-circuit/
    This is a car 12V audio amplifier circuit that has high power over than 50w Using the IC TDA1562Q Philips. Which It uses just 12 volts power supply only. But provide higher watt power to 54 Wrms at load speaker 4 ohms and there is distortion at 1% and watt power maximum 65 Vrms at distortion 10%. The watt power this size suitable for install in our cars, since …

Switchmode Power Supply For Car Audio

    https://sound-au.com/project89.htm
    The maximum RMS audio power from a given voltage V is somewhat less than: Pmax = ( V / ( 2 x √2 ) )² / R L ... where R L is the speaker nominal impedance. Thus, for a 13.8V system, this power is limited to about 6W on a 4 Ohm load.

Selecting Power Supply for Car Amplifiers - Homemade ...

    https://www.homemade-circuits.com/selecting-power-supply-for-car/
    Answer: My suggestion is technically correct regarding selecting power supply for car amplifiers, and there's no doubt about it. The manual specifies 12V as the operating voltage for the amplifier, so the power supply should be rated at a fixed 12V (regulated) and the current is immaterial and could be anything higher than 10amps upto infinity.
