Whistling noise?????

ok, everytime I drive my car I hear a whistling noise like a blow off valve comming out of my speakers. At first it wasn’t loud but now its getting louder and louder. I thought It hadd to do with my battery because it kept on dying on me so I bought a new one. The noise went down a bit, but it is still there. Do you guys think that it might be the alternator?

dood…DONT POST THE SAME QUESTION IN 2 FORUMS!!! You should delete one of you’re bandwidth wasting threads

Do you have a custom setup? If you have an amp in your car and you’re running wires to it, try to keep the audio wires on one side of the car, and the power wires on the other. If they’re run together, sometimes they create this noise.

Is the whine directly realted to the RPM’s of the engine. Meaning does the whine get louder/higher pitch at high RPM’s?
