Why won't my aftermarket stereo work on my land rover?

i bought a dual xdvd8181 for my land rover and i had to connect it manually. the power worked because it turned on fine but no sound came out of the speakers. i know which wires i had to connect to but no sound would come out. any help?|||if you have a land rover why get low quality brand like Dual?


but chances are is that the truck has a factory installed amplifier for the speakers and when you changed the radio the new one isn't sending power (remote wire) to the old amp so it isn't pushing the speakers


you will need to send power to the old amp, or rewire (run new wires) all of your speakers to the back of your new radio|||my only guess is to check your wiring
