Hi!
I'm curious how car amplifier produce 1kW or more power with 12V single power supply? I know that op-amp(transistors) have max voltage output limited with power supply. Maybe car amp first lift up voltage ?
They use an inverter to produce a higher HT rail for the amplifier - the power outputs are usually EXTREMELY exaggerated though - a 1KW amplifier is probably 100W per channel RMS, or less.
In addition to high Vcc, they also use a bridge circuit.I'm curious how car amplifier produce 1kW or more power with 12V single power supply?
yep. about 2/3 of the device is inverter and not amplifier hardware.
hmm, if i understand corectly inverter is used to produce -12V or what ? What do you mean not amplifier hardware?
