TheDarkness Posted April 3, 2012 Report Share Posted April 3, 2012 (edited) I recently installed an amplifier in my SS and i had the same "Alternator Noise" in my truck. I did run the power wire on the opposite side of the RCA's. To eliminate it i added this ground loop isolator to my headunit. Worked fine afterwards.

2006SilverSS Posted April 4, 2012 Report Share Posted April 4, 2012 After the initial install by a audio place, I've had this happen a few times and had to fix it myself (they did a crappy install if you ask me). It's been due to multiple things, bad ground, crossed wires (RCA's right next to power), and the most recent was actually the wires coming from the deck. My deck is almost 7 years old at this point and the wires are starting to age, which caused them to create a whine like you're hearing (had to do a little troubleshooting to figure that one out). I had to take the deck out and re-tape the wires really well, so that there isn't much flex in them, and the noise is gone for now. The only other option would probably be to use a filter like shown/noted above. Quote Link to comment Share on other sites More sharing options...
