Front speakers not working.

I have a Pioneer Premier 750MP that I've had since 2003 and some Kenwood 6.5" speakers. I had them installed in my 86 K5 Blazer along with some 6x9s and everything worked fine.

I installed the cd player and 6.5's in my 93 Ford F-250. I installed the head unit in the truck but got no audio from any of the speakers. I found that if I partialy plugged the adapter into the factory plug for the speakers, I got sound. I cleaned the termials and plugged it back in several times. I got pissed at it and went ahead and installed the 6.5s and got the same issue with the plug. Suddenly the speakers started working. The rear factory speakers work, but the 6.5s only play music, no vocals.

The rear speakers are staying factory until I get some 5x7s or 6x9's, I havent decided yet. Everything is running off the deck for now. I do know that the factory speakers worked with the factory radio.

Does this sound like a poor connection with the factory plug?

Last time I stuck a head unit into a Ford , with factory speakers , it was an ealry 80's Lincoln .

And the speakers wouldn't work until I disconnected the negative on the speaker leads on a hunch by my father . It almost seemed like they saved money and used one wire to each speaker , with the second going to common/ground .

are you sure the truck doesnt have a factory amp built in? did you try to juice up the remote power lead (the blue wire in the aftermarket harness...if you used one)?

I really need to quit replying when I'm drunk.
Yesterday, my neighbor and I took the deck out and gave everything a look. We determined that the deck was working properly by attaching an old speaker to it. We then checked the wires on the wire harness adapter to make sure they were connected properly. It turns out that the rear speakers were fine but the fronts were crossed. Instead of having the two white wires going to one speaker and two greys going to another, one grey and one white went to one, and the others to the other.

I guess someone got ****ed up on their lunch break and wired the adapter wrong.

That is VERY VERY weird. An amplifier's speaker outputs should never use a chassis or common ground. Im amazed it worked at all, and didn't blow the output stage on the amp.
