Yes it's possible, but you need to wire them in series so that you get ~8 Ohms, as most home systems use 8 Ohms as their standard impedence. Most cars use 2 or 4 ohms. So you'd need 4 or 2 speakers in series to get about 8 ohms. Some amps have a switch on the back to change the impedence to 4 Ohms. Basically, if you use too many ohms, the speakers are too quiet, too few, and you could destroy your amp.
