Malicious grounding causes of a multitude of problems with automobile stereo amplifiers, including unwanted cacophony and amplifier shut down when audio peaks necessitate amassed ongoing flow than the grounding step is capable of supplying. To compound the dilemma, a stereo amplifier has two grounding systems: The DC ability overhaul ground and the audio ground. These two systems must be kept seperate to dilute uproar pickup.
Instructions
The amplifier audio must ground to the same point as the source audio in the head unit.
Remove the bolt. Wire brush the bolt hole to the naked metal. Connect the amplifier power supply ground wire to the bolt. Reinstall and tighten the bolt.
3. Find a bolt under the dashboard of the car that is on the metal framework or firewall. Check it with the meter to ensure that it has a direct electrical path to the vehicle's grounding system.
4. Remove the bolt, and wire brush the bolt hole. Connect the ground wire from the stereo head unit to the bolt. Reinstall and tighten the bolt to establish the audio ground for the amplifier.1. Treasure trove a bolt into the metal chassis or floor of the vehivle that is as accelerated as viable to the amplifier. Probation it with the multimeter to ice that it has a conduct electrical pathway to the vehicle's grounding course.2.
