I have a 04 H2 that I just installed the Kenwood DNX 9140 to the factory system with the GMOS04. The problem that I am having is that the volume is not very loud. Its almost sounds like its on mute or something. Also the sound that is coming out of it is fading from front to rear on it own. Any suggestion as to what might be going on?

 

What did you install?????? ......In english??

 

If you look on the side of the box there will be a screw to turn tack a screw driver and turn it till the sound is better i had the same prob
