| Post subject: | Power factory amp using aftermarket headunit (Infinity) |
I have a 2008 Liberty with the upgraded Infinity sound system. My Pioneer appradio is all installed and functioning except for sound. I am 99% this is because I can't get power to the factory amp. I checked all my fuses and nothing is blown. The headunit will power on/off with the ignition as expected. There were two plugs coming from the back of my factory radio and I only messed with one because I assume the other is for steering wheel controls (I haven't ordered that adapter yet). The headunit has a blue/white wire for the power antenna which I wired to #7 in the diagram below. Am I missing something? I don't have any desire to swap out to an aftermarket amp, I'm fine with the Infinity system. I just can't get it to turn on! I'll be working on this all day so if you need pictures or clarification on anything, just ask. Code: 1 18RD FUSED B(+) (I.O.D.) <---fed to "always on" wire on headunit as directed by Pioneer 2 20WT CAN INTERIOR BUS (-) <---not connected 3 - 4 - 5 - 6 - 7 18GY/OR AMPLIFIED ANTENNA FEED <---fed to blue/white powered antenna on headunit 8 18GY/LG LEFT REAR SPEAKER (+) <--goes to corresponding speaker wire on headunit 9 18GY/DG LEFT REAR SPEAKER (-) <--goes to corresponding speaker wire on headunit 10 18DG/LG RIGHT REAR SPEAKER (+) <--goes to corresponding speaker wire on headunit 11 18DG/GY RIGHT REAR SPEAKER (-) <--goes to corresponding speaker wire on headunit 12 18BK/WT GROUND <--goes to ground wire on headunit 13 20WT/OR CAN INTERIOR BUS (+) <---not connected 14 - 15 - 16 - 17 - 18 - 19 18DG/VT RIGHT FRONT SPEAKERS(+) <--goes to corresponding speaker wire on headunit 20 18DG/YL RIGHT FRONT SPEAKERS(-) <--goes to corresponding speaker wire on headunit 21 18GY/VT LEFT FRONT SPEAKERS(+) <--goes to corresponding speaker wire on headunit 22 18GY/YL LEFT FRONT SPEAKERS(-) <--goes to corresponding speaker wire on headunit Note: I wired the "power on ignition" wire coming from the pioneer headunit into my cigarette wire. Maybe I need to do something similar with the amp? |

I clipped the wires from this harness below...  ...and wired them according to the schematic in my original post as seen below  This is the harness I did not touch. Originally I was thinking it was for just steering wheel controls but after closer inspection it does say AMP on it. Do I need to splice these into the back of my headunit too? There's no wires left so I assume some will be 2-to-1?

What specific model Pioneer and did you get if from Crutchfield? If you did get it from Crutchfield just call them. I had exactly the same problem wiring in my Sony MEX-BT3900U some years back. The problem was I had failed to conect the wire to power on the amplifier which is powered separately from the speakers in the Infinity Premium sound system. In my case the Crutchfield wiring diagram showed a blue wire but it's actually Blue/white |
