i installed a jvc with the proper harness for my truck a 2003 ram1500 quad cab from crutchfield. but i lost the dash speakers. i reinstalled my factory radio and they work. i checked all my connections. and they are good. the radio only had left front ,right front, left rear and right rear along with power, ground etc. i even bought another harness but i still get the same problem. any tips outthere.
yea trace your wires to thier colors. the only way they don't work is a bad radio or u are missing a connection. colors aren't fool proof 3rd party sellers arent always right.
