Determine if the noise is caused by common ground:
1. Use the headset to connect to the car's MP3 and car navigation AUX (3.5mm/0.1in interface). If the sound heard from the headset is not noisy at this time, you can confirm that the noise from the car equipment is caused by the common ground.
2. Connect the battery-powered mobile phone or MP3 (note that the mobile phone and MP3 should not be connected to any power supply in the car, such as a phone) to the AUX in the car's center console using the audio cable, and play music from the mobile phone. If there is no noise, you can confirm that the previous noise is caused by the common ground.
3. Computer, power amplifier, audio: use passive headphones to connect to the computer to check if there is noise, and use a mobile phone to connect to the power amplifier and audio to test. If there is no noise in the separate test, the basic judgment is that it is caused by the common ground.
4. After starting the car, the installed power amplifier has a current sound, and some models will also have a situation where the throttle is larger and the current sound is louder. This product can solve this problem.
5. There is galvanic noise between the power amplifier and the speaker or audio, you can install this product between the power amplifier and the speaker.
6. When the laptop is connected to the projector and amplifier, there is noise. You can connect the adapter to the power supply or use the battery via the laptop. At this time, unplug the amplifier and the noise disappears, or remove the projector and the noise disappears. Add a common ground isolator to eliminate noise. Connect the adapter to the power supply or use the battery. At this time, when the power amplifier is unplugged, the noise disappears, or when the projector is unplugged, the noise disappears. Then a common ground isolator can be added between the computer's headphone jack and the power amplifier to eliminate the noise.
