I have a 06 Cobalt SS non supercharged with pioneer sound system and no onstar Im trying to install a new stereo, I have a scosche GM13SR harness and Pioneer DEH-3400UB head unit. I connected and wired everything up but I have no audio, I have power but no audio. Can anyone help identify what the problem is and how to fix it? Heres some pics of how i wired everything

make sure non of the wires are touching first of all. that will cause the speakers to ground out and cause u to have no output of the radio and cause a short

The premium stereo (Pioneer) has an OEM Amplifier... you have to put power to it, which the wire i believe is pink.

i would verify that the blue wire in the scosche harness matches the pink wire in the stock cobalt harness. then with a meter test this to confirm its actually getting power

ya I had no audio either, then I spliced a blue wire to a pink one coming from the harness and it worked.

well, from wht I can see, you don't have the speeker wires wired in for the back of the radio harness, those would be the purple, green, white, and grey wires that have nothing connected to them, and it looks like you have the rca's wired to the cobalt harness coming from the car, so those aren't getting no signal wither. I could be wrong though, I"ve never installed a radio in a cobalt

right hes usign the rca outs from the radio for the stock amp to deliver line output vs high level output. that is the proper way of doing so

Thank you all your replies, I've made sure none of the wires are touching, i plan on putting butt connectors on everything but i want to make sure it actually works before i do this, looking at the 3rd picture, I tried switching the pink wire to the blue wire and the blue wire to the red wire and still got nothing. Any other ideas or anything i may have done wrong?

Also the scosche harness list

blue....+12V remote output
red.....+12 volt ACC switched

and the head unit list

blue...connect to system control terminal of the power amp or auto antenna relay control terminal
red(it looks pink to me).... connect to terminal controlled by ignition switch

ugh ya thats not what i meant. Ok so on the gray harness there's a blue white wire right. right, so what you need to do is either plug in the gray harness to the blue harness that's in the car stock or just count the wires/ position and verify in the blue stock plug in the car that there's a wire on the slot. This should be a pink wire in the stock blue plug

Is that the case or no?

couldntdecide15

Alright so I checked the wire positions are there is no wire on the stock harness, the grey harness blue wire is in slot 4 (bottom row) and the stock harness has no pink wires in slot 4, it does have pink wire in slots 1 and 7 (bottom row)

welp theres the issue.... problem is 2 pink wires. hook everything up and with the radio on try putting power to the pink wire in the 7 slot or whatever that middle one is and see if u get sound

couldntdecide15

You were right, i put power to the 2nd pink wire and everything works perfect now, the sound is great. Thank you for your help I really appreciate it!

so was it the pink wire in the middle or the one on the end?

Dont twist them together like that and use electrical tape bro. I am terrible with car stereo stuff but at least do it proper so no problems occur down the road. trust me stuff will go wrong, disconnect, or catch fire if they are left like that. Take into account vibrations, potholes, launching your car. Pretty much everything that goes on while your driving lol. My friends car caught fire because he didn't properly connect his amp. It sucked. Just glad he got out before the whole front half of his car was toast

did you seriously refer to electrical tape as the correct way.....
:facepalm:

EmperorJJ1

iTrader: (5)

well technically soldering is the correct way and if you do that your only options are heatshrink or electrical tape.

couldntdecide15

It was the pink wire in the middle, I moved the blue wire on the grey harness to match up with the pink wire and it worked perfectly.
