Does the car has a Bose radio?

Is up to the installer to test all wires with a DMM whenever possible.

Remote amp turn on leads are pretty easy if you don't have an aftermarket deck with a "remote" wire. Simply find an accessory lead and tap into it. Accessory meaning a circuit that isn't energized till the key is turned on. No need for a "switch".

Rookie here but not out of my league :)

Granted you do not need a switch to turn the amplifier on/off with the key, but if you should happen to have an amplifier that goes into protection mode (which hopefully never happens), a switch on the remote lead from an accessory source will prevent you from having to pull over to the side of the road to turn the amplifier off/on to reset it.
