My computer speakers in my car ??

Question

hi, i had fixed my computer speaker in my car, with power supply connected( with a switch to on/off it).

But whenever i turned on the power, there is a "eeeeeeeee" sound going on, it never stop. sounds like radiation or what kinda sound. its always there no matter i turn on the radio or mute my radio.

why is it so? anyway to remove that "radiation" sound?

i know some of u will tell me to just fix an amp and upgrade my system. but i am just trying out..

hopefully someone can tell...

Answer 1

the wires are not properly shielded are they? there is a lot of interference in a car and they need the shielding.

Answer 2

in the electronic language,"eeeeeeeeeee"sound is called humming.this humming is created by the condenser which is connected near to transfarmer to creat pure D.C current but if we cunnect it with car battery,then humming come so, to remove this error go to nearest electrician and remove the condensor.mostly the power of condensor is 25v with 2200 or 4700mfd.try it.and relace the audio cable if it's damaged.
