  1. I currently own a 2006 Chevy Trailblazer in which I installed a 7.1″ Touch Screen Stereo. Everything works great except for the two right speakers. The sound from these speakers is barely audible and slightly distorted. They also randomly start working on their own if I’m lucky. When this happens the sound quality goes up 100% and is great. This model has the On-star feature installed but I used a wiring harness during the stereo installation that bypasses its functions. Does anyone know if the sound goes through some kind of a central control unit/amp or am i simply dealing with some kind of short? (this also was an issue with the last stereo so the radio itself cannot be the problem) I would greatly appreciate any help anyone could give on this issue. Thank You

  2. Steve, we can’t say exactly what will go out if you don’t use the interface. As for your dash kit, here is the 2006 Chevrolet Trailblazer dash kit you need:

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck.

  3. I am trying to install an aftermarket stereo in a 2006 trailblazer. This model does not have onstar or the bose system. I have read the interface is required to maintain certain features on the car. My first question is, what exactly would I lose if I do not use the interface. I could care less about the chimes, but some other features I might want. Secondly, I have had a hard time finding the wiring harness or the installation kit for the 06s. Does anybody know a good place to look?

  4. First off… How’s everyone? The factory radio in the 06 trailblazer has a red alarm l.e.d in it. I know it has to be some kind of wire that goes to it. My question is: Do I look over that wire or do i need some kind of interface to make sure everything stay working properly? Thanks for your time…
