Hello all. I'm new to the site and really appreciate all of the great info I've been reading since the recent purchase of my F90BT. I have everything installed and it seems to be working well except for the front speakers. On startup, i get a pretty loud static noise coming out of the front but once it stops a few seconds later, there isnt any sound coming out of the front. The back speakers sound good. I've tried to adjust balance and fade and when the balance/fade is front left or right, there is no sound. I've verified the connections are correct to the speaker cables. Can anyone help?

 

I have a 2004 Chevy 2500 with onstar and Bose

F90BT with a GMOS-04 adapter

Pioneer XM reciever and Pioneer HD radio reciever

 

Thanks in advance!!

could be a problem with gmos adapter,

 

quick trouble shoot, switch the front and back RCA's , does the static change to the back speakers? if so then the problem is with the receiver, if not, im betting on the module
