This Legacy LA 420 amplifier features 400 watts of power, two channels (bridgeable), a two-way crossover, Mosfet power, 2 ohms stable, and THD less than 0.04%. The amplifier measures 10" x 9.5" x 2.75".

Yes the red could be for power. Yellow for video and orange could be remote/ accessories power. Ground is usually the cover. If there is a way you will screw the screen to the car body, it should work.

Unfortunately, the amp is only 2 ohm stable, so the best option is to connect each subs voice coils in parallel (2 ohms) and connect the subs in series (4 ohms).

Ok so when it's trying to boot in legacy mode it will see the hard disk as unformatted. Therefore it won't boot Windows 8 or 10. You need to get the bios back into booting uefi.
Resetting the bios should do that anyway, but there is no reason why you shouldn't be able to get into the bios to make that change. Try doing this with the hard disk unplugged so you don't risk trashing it.
