Not so long ago, connecting a car radio consisted of the simplest operations. It was enough to fold the wires of the plug and radio, rewind and insulate them. Modern connection methods are the most reliable and aesthetically pleasing.

radio tape recorder
Instructions
Step 1
Disconnect the wire from the negative terminal of the battery. Installing the radio with the negative terminal connected may result in a short circuit and electric shock. Also, a connected terminal can trigger the security system to activate, resulting in serious damage to the vehicle.
Step 2
If necessary, dismantle the previous radio tape recorder by opening the frame petals.
Step 3
Establish compatibility of the original amplifier and the new radio. To do this, find out the output impedance of the amplifier. For Panasonic it should not exceed 4 ohms. Otherwise, there may be a mismatch between the impedances of the radio and speakers, and it may be necessary to change the speaker system completely.
Step 4
Check the power connector that will supply power and signals for audio playback. It must be of a certain type (ISO). This connector consists of two parts: power and acoustic. Connection must be made through an adapter.
Step 5
In advance, establish the correct connection of each group of wires, which are marked by the manufacturer in a certain color.
Step 6
Connect the yellow wire of the power connector to the "+" of the vehicle battery through the fuse (10A). A fuse is needed to protect the wire from short circuit and vehicle fire.
Step 7
Connect the red wire to the ignition lock wire, on which "+" appears when the lock is turned on. In this case, the radio will only work when the ignition is on. For permanent operation of the radio, connect the red and yellow wires together.
Step 8
Connect the black wire to the car body or to the negative terminal of the battery. Connect the accessories (active antenna or additional sound amplifier) with blue and blue-white wires. Connect the speaker connector to the speakers according to the polarity of the radio and speaker outputs.
