I am using a standard 400 W 12 VDC to 120 VAC inverter to power my
laptop in the car.Â* While this works well, lately I've started doing
audio work with the laptop and feeding the laptop 1/8" audio jack output
into an amp hooked into the car radio.Â* While the laptop is plugged into
the inverter, I get much noise over the audio system.Â* I know the noise
is coming from the inverter, so how would I negate it?Â* I've tried about
5 snap closed ferrite cores around the power cable going into the laptop
but they haven't helped.Â* Thanks.


Has the laptop & car audio got bluetooth?
