Yes.
The wire should rest at 12V+ or zero but when the parking brake is on the wire goes 12V- .
Ensure the amplifier is turned off. Connect the positive (+) terminal of the 12V wire to the amplifier's positive terminal and the negative (-) terminal of the 12V wire to the amplifier's negative terminal. Once connected securely, you can then power on the amplifier.
take a 12v power cord splice the wire and reconnect
what is meant by "car audio"? an amplifier will not turn on if it is missing either ground, 12v or 12v accessory turn on. the respective wire colors will be large red wire for 12v battery source, large black wire for -12v ground battery or chassis, thin blue wire for accessory 12v turn on. these wires can be tested for 12v with a multi-meter or a simple test light. a car radio is basically the same wire design for power up, most radios will need 12v to the yellow wire, accessory 12v for the red wire and chassis ground for the black. test these wires the same way the amplifier is tested and repair any wires not functioning correctly. if this does not help, respond with more detailed accurate assessments of problem for further advise.
The gauge of wire that is 12 volt is 18, 14, and 16.
12v switched source. such as headlight switch or dimmer on the dash.
Red to positive, black to negative
Sounds like the computer isn't getting the needed 12v power when the vehicle is turned off. Check fuses and wires, Verify that you get 12v on the power wire, not the ignition wire. The Ignition wire only works when the ignition is activated. The 12v power wire provides power for the simple data, as in date and time, and saves that you have put in.
Typically the Orange wire is for Memory Preset/Clock (constant power +12V)

To wire a 12V 3-prong flasher, connect the power wire from the flasher to the battery positive terminal, the ground wire to the vehicle chassis ground, and the output wire to the turn signal switch or indicator. Ensure the wiring is secure and use proper connectors to prevent any short circuits.
