they work with my stock radio but with my alpine9813 they are not working. everything is wired correctly with the adaptor (color coded) any one have any ideas? does the stock bose have an amp or something? also i did not use the ground or power off the harness. it is hooked to the battery like it is supposed to be and one more thing sound is coming out of the head unit i checked it with a speaker laying around

 

What "adapter" are you using?

 

the GM one.. i think there is only one.. ever wire on both sides are connected
