Do not connect the car radio by plugging it in. You can burn out the amplifier chip, etc. 2. Do not connect the car radio to the cigarette lighter. At high volume, it will wheeze, stutter and turn off, knocking down the radio settings. 3. Do not use thin wires for power. It is recommended to connect wires for amplifiers with a cross-section of 4 - 6 squares for car radios of 2-4 squares and to the battery terminals. 4. When connecting the power wires to the battery terminals, it is necessary to install an additional fuse for 40-200 A amplifiers immediately after the positive terminal. For car radios 10-15 amps - (see the instructions for the radio and amplifier) ​​5. Do not connect the power wire and the power wire of the radio together. The red wire must be connected separately after the ignition switch. When you remove the key from the ignition, the radio should turn off. If you twist the yellow and red together and connect it before the switch or to the positive terminal of the battery, then your radio will drain the battery even when turned off. You can avoid power loss by adding two Schottky diodes to the circuit. But I would not do this. 6. Do not confuse the polarity when connecting the speakers. There may be capacitors on the tweeters. In addition, an acoustic short circuit may occur at the lowest sound frequencies up to 300 Hz. Subwoofers definitely do not like this. ************** 🔊 🔊 🔊 *************** 💡 My VK group - SUBSCRIBE!!! - https://vk.com/diy1000 ************** 🔊 🔊 🔊 *************** How to measure current / find out current loss, see the diagram in the channel community / svojfilm Connecting the radio. WHICH WIRE WHERE TO CONNECT - The standard marking of car radio wires is as follows. Yellow wire - usually thicker than others, we connect directly to the positive terminal of the battery. (This wire helps to store all the settings of the radio .... Radio station frequencies, time, and so on. And after turning on the power, it gives a powerful clear sound.) Red wire - positive turns on the radio. Connects after the ignition switch. (You must have a standard connector for the car radio. Find this wire with a multimeter or a test light. // The test light is a 12V light bulb with 2 wires. Screw one wire to the ground, connect the second to the red wire. // When you turn the key to the ACC position, the light should light. If you do not have such a wire, then look for a place to connect right behind the ignition switch. In exactly the same way. In the ACC position, the light should light). Black wire - This is the ground. Usually attached to the car body or to the negative battery. Blue wire - If you have an antenna with an electric drive, connect to it. Orange wire - connects to the instrument panel backlight. (Adjusting the instrument panel backlight will also change the brightness of the radio backlight). Blue with white - If you like clean and voluminous sound, then pull this wire to the amplifier. Pink and black - Goes to the output sound interrupter. I do not use it. The remaining 8 wires go to the speakers. Wires with stripes are negative, without stripes are positive. It is better NOT to CONFUSE the polarity. Why - it is written above White and white-black always go to the left speaker Gray and gray-black to the right Green and green-black - to the rear left speaker And purple and purple-black to the rear right. ************** 🔊 🔊 🔊 *************** Additional fuses to protect the circuit near the battery must correspond to the rating set by the manufacturer of your car radio or amplifier. ************** 🔊 🔊 🔊 *************** The sound power will directly depend on the power of the connected unit and is limited by the power of the radio.
