    Fixed the issue by connecting a wire from the RCA amplifier output on my clarion head unit, to the chassis of the head unit. This thread was a major help, thanks!

    Re: >>>Engine whine and ground loop fixes... take two

    After reading this forum I understand that Pioneer radios have a little internal fused circuit called a pico fuse.
    If this pico fuse is broken, does it also whine when the engine is off?

    My amp only whines when the engine is running. Checked everything and no solution yet.
    I also have an active subwoofer. My subwoofer and amp are both grounded to an other point, does that also matter?
    (active sub is a 200 watt peak 15A, amplifier is a 760 watt peak 60A)

    If it is correct that the whining stops, even when te pico fuse is blown. Then i will try the solution mentioned in the first post.

    Thanks in advance!
