Can car amps be used for home audio?

Hey all, I'm a penniless kid looking for a highly cost-effective way to drive a pair of Maggie MMGs. I'm both intrigued by and suspicious of the fact that class A/B monoblocks made for cars often boast what appear to be good specs for WAY less money on average than their home audio counterparts. Anyone have hands-on experience using car amps in the home? What's it sound like? Also, what kind of tinkering around would be necessary to power them from a standard 125v outlet?
