Crysler lhs, static buzzing noise in speakers when accellarating?

This is usually indicative of a ground loop causing noise from the vehicle electrical system. Long story short your stereo isn't grounded well enough.

There are two possible solutions:

1. Ground all components to the same point. This will reduce the potential and should greatly reduce any noise.

2. If number 1 is not possible (and it often is not), use a "ground loop isolator", available at nearly all electronics stores, or car audio suppliers. This device prevents a direct electrical connection between the two sources and will usually fix the ground loop.
