i've done a few deck installs, but havn't run across this problem. i'm doing the install from scratch cause it was a used deck bought from a friend(no instructions) it's a sony cdx-m610 going into a 1984 bronco custom mounted into the center console. total cost right now is $75 for the deck. problem is that with all my wires connected i can turn the deck on but there is nothing going to the speakers. using test light i can assure you there is no juice/signal going out to the speakers. i pulled deck out ran over to my 4runner plugged it in to the dash and the deck works perfectly sending signal to the speakers loud and clear. i'm sure it is something simple but it just has me lost and confused, probably in the wiring, but from what i can see and tell i wired it correctly. any help here would be greatly appreciated.
