The yellow wire (for the memory wire) is connected to the positive constant current terminal of the battery, the machine will have the memory function.2. The red wire is connected to the ACC wire of the key, this wire is also positive and controls the power switch. The black wire is connected to the negative terminal of the power supply.3. The blue wire is connected to the REM control wire of the lift antenna or subwoofer, if not, do not connect it and wrap it with a rubber sheet.4. The remaining eight wires (grey, white, green and purple) are speaker wires, a set of colours corresponds to a pair of speaker wires (positive and negative).5. Please pay attention to check whether the original speaker wire has contact iron (the original speaker wire is welded to the metal, or the speaker only has one wire thrown out, called contact iron). Contact iron will cause our high-power machine no sound, please test with a multimeter before installation, if the contact iron, please disconnect and then install.Friendly reminder.1. can not use the original car plug directly connected to our new machine, mismatch will lead to machine burn, some machines can be shared please consult customer service.2. If you buy a 12V product, please do not install it on a 24V model, otherwise it will cause the machine to burn up. 3.3. 3. Wiring the speaker cable and power cable together will cause a short circuit, resulting in the machine burning up/not being able to be switched on or the machine not having sound.Package Contents.1 X Bluetooth car MP5 player1 x Remote Control (without battery)1 x Power cable1 x User Manual
