Hey guys,the speakers in the doors, front and back doors work at random . The speakers on the dash are working all the time. I dont want to spend money on a aftermarket one yet , there are more important performance things to do first . The stereo in my 760 wagon is model sr7145. The wires are plugged in and feel tight and movement of the wires does'nt affect anything. it seems once in a while when i turn a corner it comes on for awhile then cuts out. Could it be the amplifier?, and where are they located in the wagon? They sound okay when they are working. Please help. Thanks Richie
