Eliminating Car Stereo Engine Noise

The problems in car stereo engine noise can be grouped on the basis of their origin or cause:

1. Ground Loops

Ground loops are generally the results of resistance to (-)ve ground returning from the amplifier to the battery. Sometimes, the wire or the metal frame used to send the (-)ve ground is faulty.

2. EMI Noises

EMI (Electro-Magnetic Interference) can create a big problem with high-end stereo systems that use amplifiers to power the speakers. You should always make sure that the routing of power wires and audio cables is done separately. Furthermore, the amplifier's power cable should be connected to the battery. It should go through the metal wall at the dash, and then run down the side of the vehicle to the location of the amplifier.
