    Feedback issue

    I just hooked in my sound via an aux in on my Blaupunkt headunit and I've noticed some feedback and noise coming through (you can hear the hard drive). I have this thing connected via two mini-jack extensions and then into an RCA Y-adadpter. Do I need to just go get one long mini jack extension (could this be causing the feedback?) or could it be my onboard sound card causing this? Do I need to just go with an add on USB sound card?

    I had this problem as well. Solved it using a Line-Out Converter hotwired to mini-stereo jack.



    (I later removed the white plastic connectors and wired them directly).

    This successfully removed all unwanted noise/feedback, but also reduced the overall gain/volume.

    My friend said we need to go with a capcitor wired to the power source to reduce this, but I would like to know where you go this line out converter.

    Well, on my unit it's labelled "Line-Out Converter", but most ICE enthusiasts may refer to it as a "Hi-Lo adapter". You should be able to get them from any of your local car audio accessory stores.

    I'm in Malaysia and I got mine from a local car audio store (it was next to my office actually). It cost me about MYR70.

    Be aware that it will affect the volume/gain of your audio, so you may need to crank up the volume on your PC and perhaps even the gain on the amp to compensate for the loss. But it did a fantastic job of filtering out that harddisk noise I was having.

    Ground Loop Isolator did the trick. Went down and picked one up today at Custom Sounds and no more noise and no more engine whine.
