During the day its fine but at night when I put on my lights, or ac, I get the high
pitch whine of the engine through my speakers. I wuz told to run a ground wire direct from
the battery, and I wuz also told to runa ground to the chassis....
Try a filter in the red "hot" wire. it's nothing but interference. your amp (if you have one) may be too close to the alternator, try several things, you can never tell where interference is coming from. did you replace the alternator?
Try running the power and signal (RCA) cables down opposite sides of the car. Also make sure that the RCAs don't run near the car's wiring that goes to the rear. Finally, make sure your ground wire is no longer than 18" and that it makes good contact with bare metal.
You should make the ground wire as short as possible. If you run the ground from the battery, you're probably more prone to whine. I have two big Alpine amps running in the trunk, and before I added an MSD ignition, I had zero whine. With or without lights or AC. Oh, try upping the gauge of the wire too..
AS TO THE SYSTEM WHINE, BE SURE TO RUN PREMIUM QUALITY RCA CABLES (TRANSBALANCED HIGHLY RECOMMENDED) ALSO TRY NOT TO USE SPLITTERS AND ANYTHING ELSE THAT CAUSES SIGNAL LOSS. AS PER GROUNDING, TRY TO GROUND ALL OF YOUR AMPS TO THE SAME POINT WHILE KEEPING IT SHORT AS POSSIBLE. I RUN ROCKFORD FOSGATE WHITE WOLF CABLES, I FIND THEY WORK GREAT. 3 KICKER ZR AMPLIFIERS, 3 SOLO 12" RS5.2 R3, 460i,3 1FARAD CAPS, KQ5 KICKER EQ, AND MORE........ZERO WHINE....TRY MY SUGGESTIONS AND LET ME KNOW HOW YOU MAKE OUT.
