The other day I purchased a new JVC front loader for my car. I installed it to my dash and connected my two front speakers to the 4 channels that the front loader provides and they run perfectly.
I also have an amplifier connected to my front loader which runs two 6x9 speakers and a 12''sub.
When i switch my front loader on and the CD is loading it sounds like a deep noise is coming out of my back speakers only (amp, sub and 6x9). It sounds similar to wind blowing really hard. When a CD plays the audio quality sounds perfect all around and there is no noise interference when the car is switched off.
However here's the big problem that I have. When i turn my car engine on there is a squealing/humming noise which comes from all 3 of my back speakers. Its not very loud but when I drive it progressively gets louder when my rev count goes up and when i change gears the noise gets softer and so on.
What is the problem and how can I Fix it?
