I recently bought a pioneer avh-3300bt. I have Installed several decks before in older cars but I am having some trouble. I have everything hooked up, I bought a cheap harness and it came with a ignition wire (red 12v), I hooked it up to the deck and now I can't figure out where to put it in the car. I have done my research and I found people that shoved it in their fuse boxes under certain accessories that only come on under acc, but when I try that I can get the deck to turn on but there is no sound, the car won't turn over and my gauges are messed. If someone can help me with this ignition wire it would be greatly appreciated! Ps I drive a 2010 cobalt LT Coupe. Thanks!
