alright heres the deal i got a head unit put in my 1999 supercab, so the first night i had it, my front left speaker sounded like it had blown b/c it would come on everyonce and awhile wen it wanted to.Acouple wks passed and i never fixed the speaker but know it wouldnt work at all. So i figured that it was def. blown. So today I took my door panel off and went to put new speakers in. I cut the wirers hooked it all up and there was nothing. So i change the wirers around and there was stilll nothing. So now i'm pissed cuz i think maybe the wirer shorted out wen they put the head unit in. If anyone has any info on this please resopond

 

check the connections on the hu, fuses too

 

If anything shorted, it normally would have blown the fuse. Its also a possibility that one side of the outputs from the radio are no good. Ive seen this happen before on a new radio. Go back to where you got it installed and see if they will test it for you.

 

yea i went and pulled out my head unit thinking maybe something wasnt clipped in all the way but as i looked at the wiring harness i noticed one of the wires wasnt all the way in giving me no juice to my front left speaker. So I rigged it up and it works
