audio interference using dc-ac inverter
hey everyone, i have recently dove into the world of car computers and ran into my first snag. I spent about 2 days running wires, mounting screens, etc and went to do my 1st bootup. everything worked fine except i have a large amount of static over my audio (which is an aux in on the back of my kenwood headunit).
I think i have the issue tagged down to an older inverter i am using to power the pc, but i want to see what everyone else thinks before i drop $100 on a dc-dc power supply.
If i power the computer off of household ac everything works fine, and i have also tried to hook the inverter directly to the battery which also results in the same amount of static/interference coming out of my speakers.
Furthermore if the computer is shut off, but hooked up to its power source the computers atx power supply emits a buzzing sound.
I have searched, and I think I know the answer, but i would love to hear others input.
So whats the verdict?
