[QUOTE="rucanunes, post: 21663, member: 542496"] Hello, I'm from Portugal, so sorry about any spelling mistakes or bad English... I was running a Kenwood receiver and 4 Alpine speakers om my car, everything was fine until I decided to install an Alpine Amp and a Subwoofer. Now, (and I'm sure it comes from the amp, because before that I had no noise), I have a noise that sounds like a miniature siren that rises in pitch with the speed of the engine. It's not to loud, but it sure anoyes me! What should it be the problem? Poor ground? Running a 12V power wire near the rca's? What? And what can I do to shut down this noise? Thank you, Raul Nunes [/QUOTE]
