It could be if the dealer selected the wrong menu. Now, I do not see any CAN bus wires in the Alpine kit harness so the OEM amp can be "talked to" for verification. But the computer technically could look at the front channels impedance
and determine if the Alpine amp is connected or not. VW radios can do that.
