I just installed a Rockford Fosgate 9300 HU using a Scosche adapter and i'm getting a static sound in the front dash speakers sometimes.I've pulled it out and rewired it all again and I'm still getting noise.Sometimes I have none when I start the truck and turn the deck on. I used a Scosche Antenna adapter that looks like a SPIDER has 6 different plugs on it. I taped every end that is not used. Could it be picking up interference?I have an 04 QC with the Infinity
