Stereo Problem

[calstang99]

I am trying to replace my original stereo in my 99 v6 mustang. I have all of the needed wiring and pieces, but once i got it all together, the stereo would not play. I hooked up the original, and it worked fine. The original is the split radio and CD combo and i was wondering if they must be connected to allow the system to work. I thought that I didn't have a mach system, since it is a stock v6, but I think that the stereo will not work unless it has both the original CD player and the radio hooked up. Is there anyway to bypass this or did I not hook the other stereo correctly? The deck is a pioneer premier. Please help if you can.

when u say the stereo would not play do u mean it did not power up or it powered up but no sound? also if u had the mach 460 it would say it on the grills on the tweeters which would be where the mirror covers are or on the back deck if you have a coupe. also did u use wire harness and if so did u hook up your blue/white wire from your pioneer to the blue or blue/white on the harness?
