Pioneer car stereo time set9/26/2023 The good news is that unlike car amplifiers, a car stereo draws only a few amps. What you need is a power supply to safely reduce the high voltage of a home AC outlet to a lower DC voltage that a car stereo can use. It’s extremely dangerous to try and connect a DC device to AC power – in fact, it can even explode or catch on fire. Others I’ve been to are even higher at 220V AC. Home AC outlets supply around 120V (volts, or “V”) AC if you’re in the United States and some other countries. While the motor is running an alternator generates AC power that’s changed to DC in order to charge the battery. The reason car radios use DC power is that automobiles use a DC battery to start and power the engine. In fact, car radios can work down to somewhere around 11 volts DC, with 12V to 14.4V being typical when a vehicle’s engine is running. Is a car radio AC or DC?Ĭar radios use direct current (DC) voltage to power their electronics while home electronics use alternating current (AC) with a much higher voltage. However, you’ll need to know just a few things to make sure you don’t have any headaches or potentially destroy your car stereo. You cannot, however, directly connect a car stereo to an outlet. The quick answer is yes, with the right power supply, you can hook up a car stereo to a house outlet with 120V or even 220V power.
