Although there are a lot of things that can introduce unwanted noise in a car audio system, ground loops are the single biggest culprit. Download dangdut karaoke. This noise problem can occur any time two audio components in the same system are grounded in different locations.

Finding and fixing a ground loop in a car audio system can be tough, but a lot of whines, hisses, and other annoying sounds are caused by this issue.

If those two locations have different ground potentials, an unwanted current flow, which can create noise, is introduced into the system. When the difference in ground potentials is removed, the unwanted current flow ceases, and the noise goes away. In home audio systems, ground loops usually happen when two components are plugged into different outlets. Fixing the problem may be a simple matter of changing where you have things plugged in. Unfortunately, the matter of grounding is a little more complicated in car audio systems.

The chassis — and any metal that’s in contact with it — is the ground, but not all grounds are created equal. For example, grounding one to the chassis and one to the cigarette lighter is a classic situation that can lead to the creation of a ground loop. To a cigarette lighter instead of the chassis also can introduce a ground loop.
