Use the low level outputs (RCA) from the head unit to the low level inputs of the powerd sub. An inverter (changes 12 VDC to 120 VAC, house current) will easily power the sub. Be sure the inverters watts are just a little higher than what the powered sub consumes (power watts, not audio watts). If the powered sub consumes 100 watts, get a 150 watt inverter. They cost about $50 or less for an inverter this size.
You may need a low-pass filter to keep unwanted high frequencies form getting to the sub as this will shorten it's life.

Assumably you are talking about getting a home subwoofer to work with your car system? Not sure why you would want to do that, as home audio and car audio are different animals. But if you want to, you should check the impedance of the speaker versus impedance of the radio speaker out. There are many websites which discuss impedance, so you should look it up and understand the importance of this concept before you hook anything up. You will need either to have a subwoofer out on the radio or an active or passive crossover so that your speaker will see only the low end.
