  • Wiring into car stereo w/o HU

    I have a stock amp in my car and have a list of all the pins for the input and output of the HU and the amp, howeve, there is one pin for "enable AMP" that comes from the HU. I haven't made the step into purchasing a multimeter to measure anything, but is there any chance anyone knows what signal is being put out through this line? I'm looking to wire in my computer without a HU. Thanks

      My guess is it's the 12V signal that comes on when the HU is on, to let the amp know to turn on.

        Yes it's 12v. I have hooked up the remote lead from my amp to the ignition before. Had a deck with a blown power antenna lead.

          Its a 12v input on amps and most headunits supply about 0.3A current to it when the HU switches on.
