Hello,
It sounds like you car has a factory amp which needs to have a trigger signal from the new radio. Most people use the antenna trigger to show the amp the radio is on. Here is a wiring diagram you help you get the problem fixed. Was there an option of standard or premium sound when you got the wiring adapter?
Because it looks like there are two different systems your car came with.
Please let us know what happens.
Cheers, Ken
