1. The power amplifier has a large power, and the power cord needs to be connected to the amplifier from the car battery.
2. Use an appropriate fuse for the overcurrent protection of the positive pole of the power supply.
3. Avoid routing the audio cable near the generator and ignition device to prevent radiation from affecting the sound quality.
4. The speaker wire should be selected with a wire that matches the power, and be careful not to run it together with the power cord to avoid audio interference caused by the main power cord to the speaker wire.
5. When connecting the signal line, the sound channel jacks should be connected properly and can't be connected wrongly.
6. The input and output cables should be far away from the power supply and the car computer cable, otherwise noise will be generated.
7. Power amplifier control instructions; the power amplifier control line has a 12V output when the power amplifier is turned on, so when the power amplifier is not in use, the power amplifier control line must be insulated to prevent short-circuits and accidents.
8. The negative wire of the power amplifier should be a power wire with a larger cross-section, and be firmly connected to the car body shell at the shortest distance to avoid interference noise.
