How do I connect my car subwoofer at my house?

I have a JL Audio 12" subwoofer, and a 1600 watt Sony amplier, with a Audiobahn capacitor. I recently wrecked my car, and took out my sound system. However, I was wondering, how I could connect my subwoofer to my laptop, or use it as a home subwoofer, and how the amp could be powered.
