  1. How can you tell if the radio in the 2005 chevy avalanche has a separate amplifier.. The sound is low, sometime it get loud when your going down the road but then it goes out again. I bought a new radio and it did the same thing so i bought new speaker and it still does the same thing.. Any help or info would be appreciate , trying to help a friend who just has a heart attack and stroke.. THANKS. anyone?

  2. Scotty, you will probably have to source the exact same 2005 Chevrolet Avalanche stereo from your local Chevrolet dealer or from a local junk yard. Most retailers do not sell factory radios. Hope this helps. Good luck with your 2005 Chevrolet Avalanche stereo replacement.

  3. This is great information to have… Wish I had more information about the wiring diagram for the Amplifier so I knew which speaker wire is connected to the Factory Sub under the middle console, or where I should take the low line level output from for an addition to the system. I’m trying to add an aftermarket subwoofer and amplifier and it would be very helpful to have this information for this installation. Thanks in advance to anyone that might know this and post it! :-)
