if this is still a problem for you, the same thing happened to me when trying to get my subs to work in my svt.
the interior lighting/cd player fuse blew twice while i was doing it..and eventually the internal amp on my head unit fried

so for now im back to the stock cd player..
i believe i blew this fuse when i was connecting the amp-turn on wire from my head unit, to the stock amp wire. maybe its a better idea to not have these plugged into the cd player or anything else while doing it ...
