have an 08. it does not have any dash speakers. its a non bose setup and I am going to a dnx 9960 and running 5 channel amp. so everything will be through rca. its there any trick on hooking up the GMOS-01? is there any need for me to hook up any of the speaker wires then. where do the chimes come from?

If u buy wiring harness thing to hook up HU, te chimes will come from there, the box/harness is expensive.

If u want, you can lose chimes and all and just wire HU in, without harness...

Just Onstar and door chimes... I believe it will still work even though you are not using the HU amp. I like the fact that I did not have to cut the wire harness when I used the GMOS box.
