I got into my car today and found no sound coming from the speakers (I have an AVIC3, two amps - Alpine and JL Audio and aftermarket speakers). After looking at things I found that the grounds for the amp were weak so I relocated them. The stereo worked and then stopped. I checked the grounds by putting a test light to the power wire and grounding it to the ground I was using and found that light was alot dimmer than when I initially tested it. The light then goes out.

I also noticed that when I put the key in the ignition and turn it to the 2nd position I get a clicking (almost sounds like arcing) coming from the ABS module - is that sound normal?
