I Had An 05, It Was Stolen. I Now Have An 06 An The Radio Doesnt Seem To Be As Loud. Anyone Else Notice This Or Am I Crazy?

 

I'm changing this post....I misunderstood your post. I thought you said that your radio was stolen !

I actually had an 06 TL as a loaner and thought the sound level was a little higher in that car. So I suspect that it has to do with how the output levels are set on the factory amp. One would assume the levels are set the same for every car but that apparently is not the case.
