Well I'm not sure what has happened or if I did something wrong, but I've developed noise through my speakers.
My audio/video system includes: Alpine IVA-W200, Pioneer ND-BC2 backup camera, JL Audio 1000/1, JL Audio 300/4, (3) JL Audio 10W3V3, Focal 165V2S, and Focal 130CV1.
I completely removed the interior to sound deaden it with Second Sound (comparable to Dynamatt Extreme, but better). I used JL Audio RCAs (the lower series), the Kicker 1/0 amp installation kit, Stinger 12 awg. for the subs, and Stinger 14 awg. for the components and coaxles.
When I turn the key on and the head unit starts up, it makes a noise through the speakers which sounds to me like the sound of the CD starting. In other words, if you could hear the CD start spinning and reading the data, transfer the sound to the speakers, that is the noise I'm getting. Wow, I went outside to my truck before I submitted this thread to make sure my info is all correct and I discovered something even more weird. The noise is only being transfered through my front door speakers (6 1/2" components/Focal 165V2S). I put my ear up to my subs and coaxles and nothing. I also noticed that it also makes a buzzing sound once the original sound I posted about goes away.
I don't know exactly when it started or how, but it never did this before. The only thing I have changed/added since the original install is I added a backup camera. The only thing done there was the RCA jack for the input of a backup camera was inserted, and the separate harness that includes the reverse lead was used and tapped into the reverse lights.
After the installation of the backup camera has caused my headunit's background to turn red. Basically every time I plan on using the truck, I have to turn the key to the on position, let the headunit "boot up", then start it so that it goes back to its regular color. What's weird is that it only turns red EVERY OTHER TIME its powered up. So when its in the on position, then you turn to start, it kills the power to the headunit (switch 12V) for a split second, causing it to reboot and go back to its regular screen. Now if I don't wait for the headunit to boot up and just start the truck, it will end up with whatever color background it starts out at when the key is turned on. If that's the case, I have to turn the truck back off and have the door open so that the power is killed to the headunit, before I restart the truck. The truck is designed to keep the headunit on after you turn the truck off for several minutes or until you open the door.
