PCGUY112887 Posted September 11, 2007 Report Share Posted September 11, 2007 The coupe GP I bought as my project car came with a shitty DUAL brand head unit. No model info on it, just has the DUAL logo on the front of it. I pulled it out of my coupe and pulled my Sony headunit out of my sedan GP. I stuck the DUAL in my sedan since I am selling it, and swapped over the wiring harnesses so I didn't have to rewire everything. For some reason now, I can't get the head unit to turn on at all! Hooked up the same as my Sony one, I have a blue and Orange wire hanging off the cars harness unused just like the Sony setup had, but it just won't power on! I thought maybe some of the splices pulled loose, so I undid all of them and put them back together. No go. I highly doubt there is any security lockout on this POS headunit. Any ideas?

my95z34 Posted September 11, 2007 Report Share Posted September 11, 2007 so you are using the dual wiring harness on the sony, and vice versa? Quote Link to comment Share on other sites More sharing options...
Ryan from Ohio Posted September 13, 2007 Report Share Posted September 13, 2007 Fuse? Quote Link to comment Share on other sites More sharing options...
slick Posted September 13, 2007 Report Share Posted September 13, 2007 Check fuses. Pull out the DMM and do a continuity test with the ground at your HU and a chassis ground. Check to make sure your getting 12v on the constant and switched line. Quote Link to comment Share on other sites More sharing options...
PCGUY112887 Posted September 13, 2007 Author Report Share Posted September 13, 2007 Well noticed that my doors stopped autolocking/unlocking when I drove and went to shut the car off, and noticed no alarms for headlights so I knew it was a fuse. Started to look around, blew the 12+ IPW fuse or some shit like that, it's a 15A. Rewired the radio since the lines pulled apart and shorted out and all is good now! Thanks.
