You need to use a wiring kit to power up the amp, with the input to the amplifier coming from the sub-out on the headunit.
Then just connect the sub to the amp using speaker cable.

you could, but you will probably find there is a volume control on the headunit for the sub, hence the specific pre out
they arent going to mass produce parts they dont need and cost themselfs more money for no reason
