  • Whine and interference with PIX X-3

    Hello all,
    After installing my carputer in my 2005 Honda Accord, I am experiencing alternator whine. I can also hear one input on another on the X-3. (e.g. I here XM, but only from the left front speaker, when on X-1). On CD, I hear XM and get alternator whine that varies with the volume level and the RPM of the engine. If I unplug the RCA's from the carputer, all is golden. Is this a simple ground loop or is something else going on? The X-3 is powered off the cigarette lighter located in the center console (I hardwired it in as my monitor covers the lighter anyhow.) The Carputer is grounded to a bolt under the front passenger seat. Hearing XM on multiple inputs is especially baffling to me...

    Thanks for the help.
