    HU: Alpine CDA-9807

    For the last year, I've had Sirius but when my contract expried I decided to switch to XM. When using Sirius, I used their "Sirius Direct Connect" for Alpine headunits, and that worked great.

    Now that I'm switching to XM, I had to buy the Terk XM Direct Universal Tuner (XMD1000) AND the Alpine Smart Digital Adapter (XMDALP1000). So I disconnect my Sirius stuff, and install the XM stuff, turn the key to the accesories position and voilla, everything works dandy. I can pick up the Preview Channel clearly with no static or feedback.

    The problem came when I started the engine. Once the car is running, the sound gets very crappy and I can hear a whine in the speakers that corresponds directly with the engine. If I rev the engine, the whine increases in pitch.

    I didn't think it could be a grounding issue, because all the power comes directly through the AINet cable from the headunit, there's no splicing into the wiring harness or grounding to a random bolt. I took both pieces of equipment back to the store and exchanged them. Same problem.

    Any help?

    Ive only seen this problem once..and it was a bad alpine tuner in this case...i would replace that.


    You could TRY taking a piece of wire, ground on side, and touch the other on the terk RCA calbe..and see if that helps..

    the year before terk was bought, we had no problems... the year audiovox bought terk, we did... like the new pioneer decks would not recognize the old terk, the alpines were having problem with sound, the bad straight from the box thing, shitty fuse holders on the terk commanders that the tabs fall off... but since it's going to turn into cell phone type business(where the stores give away the equpiment, for less than they pay for... only to get a tiny kickback in 6 moths, if the person still uses the service.), the real companies stopped making their own xm stuff... then pioneer decided to get back into it, when they saw how crappy terk was.

    try just removing the radio ground from the harness, and ground it to the chassis of the car... sometimes when a ground is bad, the antenna will work as a ground... and you wouldn't notice a problem, until you add stuff to the stereo system.
