If your remote wire isn't responding in the back of the head unit. Try this fix
Make sure your power wire is hooked up, and make sure you check your grounds.
Sometimes your wire at the Amp, may not be tighten all the way.
My fix, is simply attaching your remote wire from your amp, to your radio fuse or ignition fuse. It will work, just as it did before. Turn your key and start bumpin again.
