So I have a bit of a weird problem. I was working on a stereo install in my car today (didn't finish) and went to pick up something from home depot. I started driving and noticed that I'm getting a loud alternator whine noise from the right front tweeter.
But here's the thing - it's not connected to anything! The only components currently connected to it are the passive crossover, the woofer, and a line out from the crossover. The line out is terminated in an Alpine PDX amp speaker plug, which is not connected to anything, and resting on the trunk carpet. The left front tweeter is currently sitting in the same state, but does not produce any noise.
The only thing I can think of that may be causing it is that there is a large power run down the affected side, which runs close to the passive crossover (within 1 - 2 inches). The crossover HAS to be the source of the problem, as nothing else is connected to the speaker emitting the whining. Driver's side is setup exactly the same way, and has zero noise coming from it - the major difference is, there are no thick power cables going down that side.
Relocating the passive crossover away from these lines would be very difficult (they go down the entire passenger side), and re-routing these power cables is not an option. I found EMI shielding tape on Ebay - my thoughts were to get some and wrap it around the power cables where they pass near the crossover unit. Don't have any experience with this stuff though - I want to know if it at least has a chance of working before trying it out.
Has anyone used this tape? Anyone have any other ideas?
