Firstly, I wouldn't because you could damage it if it isn't hooked up right. Subs are for low frequency repsonse, and you need something called a crossover to filter out anything too high for the sub (like vocals). If your home stereo has a subwoofer output though, that's ok, as that is a crossover.

Secondly, you need to find out what the RMS and peak wattage of your home stereo is, or you could blow your sub. Also, I hear, that heavily underpowering a sub can damage it also. If the RMS wattage of the sub is higher than the home stereo and the peak is lower, then you can use it, but don't push it. If the RMS wattage of the home stereo is higher than the sub, then don't use it at all.

I assume you are transforming the power from AC 240v to DC 12v?
