Power/Antenna control wire connected to car harness from head unit if using amp?

About to install an amp. Does the power/antenna wire (Remote turn on wire I presume) wire from head unit to car harness, and amp as well? Or just head unit to amp?


  • I am guessing you are using a wiring harness to hook up the new head unit to the existing car wiring. If the wiring harness has a place for the remote wire than hook it up to the jumper harness and also to your amp to turn it on. If not then just to your amp. I say this because some cars have built in amps that use that wire to turn them on.
