since it was the black wire comming out of the radio and labeled "ground" i just ran a new wire down to the chassis.but the other wires which were connected together remain seperated now.all other systems work fine so i have no clue what they are for but i guess it doesnt matter really.
checking those wires with a volt meter i found 2 wires had continuty with the ground,one had 12v. and one wasnt a ground or a hot.
obvously,i am assuming the hot with the grounds were causing the short.its just a weird system because it seems the truck has a reverse polarity meaning the negitive is the control wire.like out of the headlight switch has no power,as a typical switch would have 12v coming in,when you flip it to on it makes contact and sends the 12v. to the light or what have you.
anyway,thats all unimportant,i didnt do anything to the speaker wires and it worked fine before i cut the grounds apart.i just wonder if those speaker wires go to an amp and cutting those grounds one feeds the amp.
again,just dont know and was hoping someone can enlighten me with some experience or ideas....
