This is only used if your vehicle has a motorized antenna that pops up only when the radio is on, then retracts when the radio is off. A voltage is sent from the stereo through this wire to a relay which applied power to the antenna. If you don't need it the wire from the stereo should be capped off to prevent a short occurring if it were to ground out under the dash somehow.
Some headunits share a power antenna & remote wire are the same wire. If it is hooked up to power antenna and not hooked up to factory amp there is no signal to tell amp to power up
the ACC wire from the stereo is connected to constant power (+12V)
red
the black wire or yellow wire are not connected right
make sure your antenna wire from car is hooked up. stereo will have no sound until it is.
DO NOT go putting wires into your fuse box, this could cause problems in the future, if you have a power Antenna wire on the back for your radio, [Blue in Most cars, but refer to your cars manual.] Splice the REMOTE wire from your amp into the Power antenna wire OR if you dont have a power antenna wire. if your car has RAP [Retained accessory power, or your radio doesnt turn off until you open a door] its a good idea to use a 12V Accessory wire. any more questions just email me. Note : Many head units will only energize the power antenna wire when the radio is on and then deenergize it when you switch to cd. So your best bet is to just go with the accessory wire method described above.
the power antenna is located on right front. I jacked my car, and removed the right front wheel. Then there are some small screws which are keep the inner fender plastic. unscrew them. You can reach with your hand the power antenna. Unplug the power wire, and the antenna wire, and unscrew those small (8mm) screws which are holding the antenna in its bracket.
Check the fuses, remote wire, and power wire first of all. If that doesn't work you might have wires loose somewhere.
