How to connect the vehicle 24V dual 12V audio power supply?

Yes, you can connect three wires directly from the battery. For the convenience of control, a 2.5 square three-core soft copper wire can be connected with a three-wire switch as a separate power supply. The 24V battery is actually composed of two 12V batteries connected in series. When wiring,+12V is connected to the total of 24V, and 0V is connected to+12V.

Any computer speaker can pass through the three-wire switch, which can be replaced by the 10A 3P air switch to meet the normal working conditions of the speaker. You don't need to buy an inverter, you just need to handle and fix the line.

Extended data:

1, REM refers to the speaker control line, which is used to connect the position where the automobile ignition key is turned on;

2. 12V is used to connect the "+"terminal of the battery in the car, that is, the positive electrode of the battery;

3, GND, because the car uses a single set of 12V DC power supply, the+"power supply is the+pole of the battery, and the-power supply is the whole frame.

Installed in the car: Rem picks up the car key, 12V is directly connected to the battery positive electrode, GND is connected to the battery negative electrode, and it can also be directly connected to the car frame, so that the sound will automatically turn on when the car is started, and automatically turn off when it is closed.
