I'm curious why Lexus insists on using all different part numbers for basically the same amp (functionally). Looking at the schematics, wiring, pin-outs, etc, they all seem to be the same amp. I know they may have different mounting holes/hardware, but that withstanding, what else differs. Even the Toyota Highlader JBL amp has the same pin-outs as a ML.

Basically, why can't we use an RX amp in an ES, or any other car for that matter, as long as they have the same pin-outs and meet the requirements.

Anyone have some insight on this? Anyone have links or information they can share?

Thanks!
