Weird sound problem

[ExplorerXLT91]

I'm trying to put a CD player in my Explorer. It's a Pioneer deck. I bought the Premium sound wiring kit with the amp bypass. I hooked it all up and I only get sound from the left side speakers. When I move the balance on the CD player all the way to the right, I still have sound on the left side but when I move it all the way left, I have no sound. I double checked the harness and I matched all the colors up right. I unhooked the amp bypass and re-connected the amp, used the turn on lead, and I still have the same problem. Is it possible the speaker leads in my connector are different than others?

Check the wiring to the speakers, but it sounds like some wires are crossed. If the left side works until you turn the balance to the left side, some wires are crossed, or the deck is defective from the manufacturer.
I have wired in a lot of HU in my time and it is pretty straight forward, connect the colors. If you did that and disconncted the stock amp, then you did everything right.

It's gotta be crossed wires. The HU worked fine in the last 2 cars it was in. I figured crossed wires would be the culprit. Thanks.

EDIT - I swapped the OEM HU back in and all the speakers work fine so at least I know now that there's a problem somewhere at the HU instead of in the amp bypass harness or something stupid like blown speakers.

I dunno WTF the problem is. I unhooked what I hooked up for the speakers on the HU harness. I tested each set of colors individually. All the HU leads work. I can't get any sound out of the right side speakers at all. I tried all the leads from the HU and get nothing. Can someone please help?

I have same problem

This sounds similar to my problem. Front left speaker sometimes cuts out when I hit a bump. Turning up the volume sometimes bring it back.

I know the speaker is wired in solidly - I just put in an aftermarket speaker because of the problem, wired it in good, and the problem was still there! Wiring at HU also checked - all the plugs are in tight and no amount of wiggling makes any difference.

So it must be a loose connection somewhere between, but not at, the speaker and the HU. This is bad, as most of the wiring is inaccessible.

So...anyone know the easiest way to access all the audio wiring behind the dash?? Will also post this query as a new thread.

Disconnect all your speaker leads and try one set at a time i.e. left front then right front. If you still have no sound, the HU may be shot. Just make sure you are wiring them correctly. You can get that same problem if you wire say the two front pos leads to the left speaker and two front neg leads to the right. Right speaker won't work and left will work on both left and right balance.

I figured out the problem. The pins inside the harness weren't lined up properly. The right side pins were going into the left side leads and the left side was going into nothing. I just had to bend those up a little bit and it plugged it back in and it works fine now. What a bunch of **** tho. I've had this thing torn apart for 3 days now and been getting pissed off and testing leads all over the place trying to fix it and it's something stupid like that.

ha, that's what i was going to say. i hate when the 1st gen x's come in to the shop. i always have to wrestle with the d@mn audio plug to get the long, thin pins to line up.
