Not a good product for the $$, but it worked
2006 Audi A4
Crutchfield Customer Review (What's this?)
I installed this and a Kenwood KMM-BT318U in a 2006 A4 without Bose, with the ISO style connectors (uses has the red harness). As many people are saying, the rear speakers and OEM subwoofer were very quiet after installation. As everyone is also saying, the directions are completely useless. I have installed many head units and amps, and still had to call tech support. The guys at Crutchfield were great though, and quickly told me what I needed. I plan to make an online video to help everyone in my situation out, but for now, HERE IS THE MISSING INFO YOU NEED: -Connect your 8 speaker wires together, often this is color coded. -Connect head unit constant power and ground, both my kenwood and the C2r were yellow/black. -Connect the head unit trigger wire (mine was red) to the C2r trigger wire. This is the red wire without a white stripe that is hidden in the cluster labeled "navigation outputs." -Connect the amp trigger wire from the head unit (mine was blue/white) to the C2r stock amp trigger wire, which is blue/white. -Connect the head unit steering wheel controls if it applies to you (for kenwood it is a blue/yellow wire) to the PAC blue/yellow wire. Most others are a 3.5mm jack -Connect the RCA's to your head unit. Congrats, after all of this your rear speakers will still be very quiet . In conclusion, do not waste your time with this PAC nonsense. Get a different harness. I found out about it too late.
Pros: -It did work -The steering wheel controls work half decently, definitely get them if for some reason you still choose to buy this product. -It converts Audi's weird euro trigger to a 12v trigger.
Cons: -The rear speakers are very quiet, I had to put the fader very far back -With the fader this far back, your music can't get very loud -Directions are poor, I have an engineering degree and couldn't use them -For the price, you can just buy new speakers and wire them to run off of your head unit, and then power the head unit with your own constant 12v, ground, and fuse tapped 12v trigger.
