The radio tape recorder is an integral part of the car, without which many motorists simply cannot exist. Without music, the car becomes just an iron box. But how to properly connect a radio tape recorder, for example, of the Kenwood brand.
Locate the ISO plugs on the radio. This type is the international standard for connecting car audio systems. If your radio uses an individual plug, then an adapter must be included in the kit. If it is not there, then you will have to buy it at your nearest radio parts store.
The simplest connection method is as follows. Carefully cut the wires from the plugs and connect them according to the color coding. Insulate all connections thoroughly with electrical tape. However, this method is unreliable and makes it difficult to replace the radio. Therefore, it is better to install the pins of the ISO connector so that in the future it will take you a few minutes to change the audio system.
Inspect the radio plug. The brown connector is designed to feed the audio signal to the speakers, and the black connector supplies power to the radio and is required for various additional options. Power supply with a separate wiring from the battery to the radio itself. Remember that the red and yellow wires that are used in the power supply have different functions.
The yellow wire powers the memory, and the red one turns off the radio and connects directly to the ignition switch. Connect these two wires in parallel, then the device will be turned off from the button on the radio panel. Sometimes this can create problems if the radio is designed in such a way that its amplifier is powered from the red wire constantly, which can lead to a rapid discharge of the battery.
Put an ordinary switch, button or toggle switch in the break of the red wire. Do not forget to turn it off when you park for a long time. You can also use a simple scheme to make the radio turn on and off automatically from the alarm. After connecting all the wires, insert the device into a suitable place on the panel and secure it.
