FOCAL questions and answers

Product questions, troubleshooting answers, and setup help related to this topic.

I have a Focal sound system in my 3008. The sound from the speakers is very good when playing music. However, sometimes, but frequently, when I start my car, there is a hissing sound from the speakers. This sound continues while driving, and when I hit speed bumps, there are cracking and popping sounds. I haven't been able to pinpoint which speaker it's coming from, as it changes. The popping sounds sometimes come from the left tweeter, sometimes the right, and sometimes from the rear. I thought I was the only one experiencing this problem, but many others are. There are many people experiencing this issue in international forums, but no one has found a solution. Some have even changed the amplifier, but the problem persists. It's an annoying sound. Authorized services don't have a solution either, as they haven't experienced it.
