Richtofen Posted July 13, 2019 Report Share Posted July 13, 2019 I have a 2001 Deville with no bose or on star. It has a factory Delphi amplifier. I cannot get my double din pioneer stereo to power on at all no matter what wiring harness I use or if I use a whole different head unit entirely. My stock radio works completely fine and I have installed aftermarket speakers and a subwoofer that work with the OEM radio and amp. What am I doing wrong with the head unit? It just won’t turn on. the only thing I haven’t done is cut the OEM wires and hard wire it directly without a harness Quote Link to comment Share on other sites More sharing options...
rockfangd Posted July 14, 2019 Report Share Posted July 14, 2019 Even if you did it will not work anyway The oem head units are always powered. They are turned on (ignition) via datalink. Therefore you would need a interface that sees the datalink and provides a ignition(+) output. Or you would have to run one from a ignition source. Someone else will likely chime in on this as well. I am not sure on powering up the amp as well. I cannot recall if it is powered by the radio or by Datalink. Likely it is by datalink as well. I choose not to change my radios in Caddys.
