For OEM remote signals a relay is required -more so if multiple amps are to be installed- for protection and 12V stability. Remote lines can draw up to 1A per amp (thus the commonly recommended 1A fuse at each turn on line) so this is not something that can be easily overlook at time of installation.
IMO, the average installer simply wants to
gangbang installations the quickest and cheapest possible, so details like this get lost while customers end up paying later for that mess.
