Hi there! I have an audiovox EQ/Booster that I am trying to hook up to a stock Ford AM/FM/Cassette deck. I am using an adjustable high/low adapter between the two, but no matter where I ground the EQ to, I end up with alternator whine and electrical noise whenever the truck is running. The truck is a 1983 Ranger and has a metal dashboard, and the deck is an electronic unit from an early to mid 90's Ford. I have also tried isolating the brackets that mount the EQ underdash with rubber pads so there is no metal-to-metal contact between the two, but that didn't help. I have tried pulling power for the EQ from the factory stereo wiring, and from the cigarette lighter wiring. I plan now on running a separate wire direct from the battery to see if that helps. Any suggestions or advice? Thanks!

go to radio shack and pick up a line noise filter.
the +12V line may be your source too though usually alternator whine is caused by a ground loop

also try their ground loop isolator, they've worked for me in the past, are you using RCA cables or going line level inputs?

Thats a great idea to remove the power source from the factory wiring as noise can enter through these wires it is always better when adding a component to run your own wire to a source away from the factory wiring . Also stay away fom the fuse panel as this is a noisy area as well. Maybe also try to ground it on the chassis of the car instaed of the metal on the dash. factory wiring is no good as as source of power because they tend to run multiple components off those wires. Run your own wires see what happens if no help then try to filter it but try to get rid of it first. A filter is really a temp fix otherwise known as a band aid it is always better to find and fix then to just throw a filter on. good luck posted_image

yes it's a cheap fix but we are talking about an audiovox EQ/booster here, not exactly a pair of AudioControl EQTs or an EQX.
