To whom it may concern I bought a Pioneer DEH 16 and I'm having trouble hooking it up. I'v connected the Speakers wire according to the color code and they seem to be fine, there's a black which is the ground and that is okay also. the problem I'm having is that there is a yellow, a Red and a Blue/white. When the Yellow is connected to the Hot Lead at approx 11 decibels the unit starts to blink, when I reverse the wiring I have to reset the Stations, don't know what to do with the Blue/White Wire. I have a 97 Camry and there's a built in apparatus (don't know if it is a crossover or preamp). Any help would be greatly appreciated. Thanking You in advance Zorro75
