You would need a large 12v DC power supply to run the amplifier. Not cheap.
What were you doing to use for full range audio since that's only a subwoofer?
Your laptop would need to connect to an amp for all the speakers not just the subwoofer.
It's feasible that you could run the output of your laptop into the aux of a car head unit where the amp is located and run speaker wires into the house. The car would have to be running the whole time.
