awak333 Posted December 3, 2013 Report Share Posted December 3, 2013 I'm fairly new to the car audio scene, but I am always willing to learn. I just purchased a new pioneer head unit from walmart to replace my dvd player I had (wasn't so friendly to my subwoofer) for my chevy HHR 06. The H/U came with 3 main power wires: Yellow (constant 12v), Red (Acc ignition switch), and Black (for ground). I connected all those wires correctly to my harness (which connected my DVD player without any hiccups). The only wire I didn't use from the harness was the orange illumination wire which I have taped off. Now, when I crank my car or switch the ignition to acc the H/U will not turn on. I have checked all the necessary fuses under the hood and under the passenger console, only one fuse was blown but had nothing to do with the radio. After further investigation I decided to see what would happen if I touched the connected ACC wires with the connected Constant 12v wires and the H/U turned on, but this would drain my battery if left wired incorrectly. What could this problem be? Just earlier today it was powering my DVD player just fine... I should also mention, the stereo shop before had my Remote amp wire wired into my ACC wire when my DVD player was connected.. but the amp always turned on and off with the car, no idea why but I thought I should mention.

Miguels Posted December 3, 2013 Report Share Posted December 3, 2013 the problen could be that it does not have sufficient voltage to power the head unit.. when i was installing my head unit a few months back.. i got my light tester and with ACC on on the light would turn on but the H/U didnt. i got my dmm and it only read 9 volts.. i looked for a 12 volt wire and it now works.. sucks that i thought the hu was bad so took it out before double checking my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

I can't find my DMM anywhere right now so i have no idea if its receiving proper voltage. Link to comment Share on other sites More sharing options...
ghostlyrich Posted December 3, 2013 Report Share Posted December 3, 2013 did you install a pac module? if not the red needs to go to accesory line in steering column if you not good with car electronics and using a meter you might want to consider the module. module is pac c2r gm11 it also gives chime other wise you loose that function My youtube channel https://www.youtube.com/user/ghostlyrich Mazda 3 2006 Build (R.I.P) http://www.stevemeadedesigns.com/board/topic/172728-mazda-3-2006-stealth-build/ Volkswagen GTI 2011 Build http://www.stevemeadedesigns.com/board/topic/192979-vw-gti-2011-build/ Jeep 2015 Build http://www.stevemeadedesigns.com/board/topic/201493-my-new-jeep-2015/ Link to comment Share on other sites More sharing options...
awak333 Posted December 3, 2013 Author Report Share Posted December 3, 2013 did you install a pac module? if not the red needs to go to accesorycan always grab it from the steering column if you not good with car electronics and using a meter you might want to consider the module I do indeed have a pac module installed. The pac module works fine. I noticed the red ACC goes to the Pac module and then to the H/U.. the module has full power, though. Link to comment Share on other sites More sharing options...

I don't understand what went wrong. Link to comment Share on other sites More sharing options...
jarrius Posted December 3, 2013 Report Share Posted December 3, 2013 How diff you test the fuses? I can tell you from experience that just because a fuse looks good it may still be blown. Make sure to test them with the dmm just to be safe. 2012 Chevy sonic1xSQ HDC3 12 D2RF R1200d 140 square foot of Q-Mat(soon to be installed) 140.2Db sealed on the dash with TL 142 DB sealed on the dash with another meter (was dead on with the TL at a show i was at) 141 on music. strangeduck,on 02 Jan 2014 - 01:39 AM, said: when my car spins out i just put the car in neutral, turn in the direction i want to go and pucker my asshole Link to comment Share on other sites More sharing options...
finkster Posted December 3, 2013 Report Share Posted December 3, 2013 For the head unit to turn on, the red and yellow need hooked up to positive and black to negative. See if it turns on from that straight to the battery.
