i have did everything. i did the grounding rca in back of deck trick, grounded deck in different spot, cleaned all grounds, ran power wire from different spot, i have tried a couple inline noise filters. nothing seems to work. when the car is running is the only time i get the wine. if the apms are on rca's disconnected from deck no noise so not amps. if amps are on deck off rca's plugged in wine is present. i do hear a small wine coming from the alt could this be the problem?
the only things i can think of is getting a new alternator or getting a noise suppressor for the deck. like this http://www.sonicelectronix.com/item_...AC-CSS-12.html
