No Sound After Audio Install, 1991 Chevrolet 1500 C Series Pickup

I have a 91 chevy 1500 c series pick up and after installing a dual xdm17bt audio receiver I can't get any sound what should I, do?Kevin C.

Did you purchase the wiring harness for the vehicle? Did the last radio work?

no the last radio didn't work and I had to cut the wires and rehook them I got power but no sound I can't figure out why the wiring is different then the horness that came with the receiver. HELP!!! Kevin C.

The wires in the truck, what color are the wires? Disregard the ones you have connected for power.

tan gray blue light blue yellow green light green brown and black I've followed the color code but with no luck. Kevin C.

What color code did you follow? Left rear = Brown positive Yellow negative? Right rear Dk. Blue positive Lt. Blue negative?

left front tan and gray right front dark green and light green left rear brown and yellow right rear blue and light blue. I, used the wiring hornnes that came with the receiver so I,had to connect it by changing the order of wiring constant is orange in the truck and the ignition is yellow and so forth red to orange and yellow to red either way I, still don't have sound and when I, go online to find out where the factory amp is located I, can;t get a straight answer. I.m sure if I, can find way to bypass the factory amp I, could probably bypass it and get the sound. Kevin C.

I, need a manual on how to install a after market dual XDM17bt receiver in my 91 chevy 1500 c series truckKevin C.

If you had those wire colors they are the wires that were plugged into the factory amplifier. One of 3 possible causes. 1. All of the speakers are bad. 2. You have a shorted speaker or a grounded speaker wire. 3. That Gem of a radio has no output.

The radio I, installed was a radio from my other car and worked great, the speakers works as well, everything I, read leads me to a factory amp, the factory system was a three way system. I, can;t seem to get a answer on where it's located, I. would like to bypass the amp if possible. But first I, need to locate it. Kevin C.
