Are you experiencing a loud whine in your stereo system when you hit the accelerator? This can be a common issue with newer GM vehicles. While there are many solutions out there, such as wrapping wires around your RCA cables, these solutions often don’t solve the problem. In this post, we’ll show you how to fix this problem once and for all.

The solution lies in a noise filter that works by dissipating the frequency into the ground. This is an easy fix that doesn’t require any complicated filters or other devices. It’s important to note that noise suppression systems should be a last resort, as they rob your system of sound quality and can cut out frequencies, making your stereo system sound worse than it should.

At Custom Works, we recommend the use of a noise filter to solve the problem. We recommend upgrading the wires, so you have the alternator lead coming into the alternator, the part of the noise filter, and the alternator out to where it normally goes. The noise filter is then grounded to the chassis, which takes the frequency and dissipates it into the ground. This is a simple solution that is easy to install and will solve your alternator whine problem.
