  1. The constant 12v on a 2007 Chevy Cobalt is Yellow. You can run a wire to your fuse box into the sunroof slot to get 12v switched power. This works even if you don’t have a sunroof.

  2. Vincent, you will probably have to source the exact same 2007 Chevrolet Cobalt amp from your local Chevrolet dealer or from a local junk yard. Most retailers do not sell factory amplifier. Hope this helps. Good luck with your 2007 Chevrolet Cobalt amplifier replacement.

  3. wanting to replace factory pioneer amplifier with another pioneer amplifier. where can i get one? i no longer have the original amplifier to get numbers off of it to replace it. anyone?

  4. I just wanted to get this message out there to the people who are dealing with the required Scosche Interface for 2007 Monte Carlo. If you have the most common version (No OnStar, non-Bose system, non-amplified system) you do not need the Scosche interface UNLESS you really want to hear the door speaker warnings (low fuel, headlights left on, turn signal clicking, etc). The Scosche box claims that the AC fan speed will be affected, but this is not a true statement for this particular car (specifically a 2007 Monte Carlo LT)
