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!
The strangest thing is that the noise it's ONLY on the rear right speaker. The
speaker that it's near the power cable of the battery of my car. I have a BMW
318 Cabrio that has the battery on the right side of the trunk.
What in hell can be causing this anoying noise in just that speaker? I had no
noise before the instalation of the amplifier...
