    Gmos 06 Problems Help Please!!!

    I have a 2004 DeVille and I brought an aftermarket radio also the GMOS-06. I thought I was ready to install. NOT!! For some reason I get power to the radio, BUT NO SOUND!!!! When I put the stock radio back in everything seems to be working fine. Thus leads me to belive, it is the stock amp thats not cutting on or something. This seems to be the hardest radio that I ever had to install. I dont have the BOSE System. Just the plain old regular stock Amplified system. Is there anyone in the world having, or has had the same problem??? Please help

    Yes I do have the four RCA one. Should I turn it down or up. Also, what does that knob do?? I thought that it was for onstar volume or something. Thanks for your help

    its the gain knob for the low level sound signal sent to the amp

    the 4 rca model sucks and it plauged with many problems the 1st gen 2 rca model was much better....
