What or is the best In-Line Noise Suppressor that I could use to get the alternator whine from my Magnum S-9. I drive an '06 Peterbilt and when the alt. starts charging you can't hear nothing. I've had the batt. terminals cleaned and it helps for a little while. When it starts whinning you can either turn the lights either on or off and it helps but not all the way. I have thought about running a wire straight from the batt to the radio too. Any and all help will be greatly appreciated!
Thanks
