2007 Chevy Trailblazer Deck Install

[jowens]

I recently purchased a 2007 Trailblazer with the Sun and sound package in it. Shortly after buying it, i had the headunit replaced with a Clarion MAX675VD. THey used the GMOS-04 adapater to interface with the factory amp. The problem was the volume was incrediably low even with the radio turned almost all the way up. The adapter had another issue of no mute capability when using onstar. It would just power off the radio. They tried to use the GMAH24 next. It solved the problem of muting with Onstar and volume, but it introduced a ton of hiss at low volumes. I am guessing it is an issue with the high level inputs running into it. Does anyone have any suggestions on what to do to fix this harnass or suggestions on the GMOS-04?


I did make a call to Metra over the weekend. They said the GMOS-04 was probably going into protection because of the voltage level on the preouts. I also did some research on the GMAh24 and think that is the incorrect harnass. It should be the GMAH24b. If you have any suggestions or ideas, please let me know.
