how will you power it? you would need a power inverter to convert from DC to AC. The only other problem I could see is keeping it in one place. Other than that it should be just like a bass tube.
In the theory of sound..... car subs and boxes are made for a smaller area. Home theater subs, they are tuned and built for larger areas. that is why u cant really build a home theater sub unless u noe a lot about audio. Car Audio is by far quite e z to work in. But a home sub in its own box would sound like shit in a car. I've personally experienced it wen i was an amatuer in car audio.
