No sound from any Front Speakers

[Sevenevez]

So, EVERY speaker in my 2003 Denali works, Except for both front doors and pillars don't work at all.

Before i tear apart both doors and the dash to troubleshoot, any knowledge or ideas you guys have would surely help and be appreciated.

Probably a dumb question, but the fader didn't get set to the rear only did it?

Is it the stock head unit?

yes, stock unit. but it looks at one point whoever owned it before me had a custom system. so who knows.. i suppose i should just tear into it and start testing wires

That's where I would start first. Just need a spare speaker and some jumper wires to rule out the head unit.

I had my connection on the speaker coroted. I clean the connection and they worked again!! Possibly you have the Same problem

well, first things first, i took off both front door panels and pillars just to verify that even had speakers at all and that they were connected. then i took apart the dash and traced the wires (green/dark green/grey/tan) and they went into the radio/harness. my only thought is the front channel of the head unit is bad/blown.

figured it needed an upgrade anyways and bought a new double din head unit and steering wheel controls harness etc..
