Jesse,
Use some of the free software out there to "model" a nice box that you could build. The amp you are looking at is a good amp. If you feel that it might be a while before you pull the plug on your SVS purchase, you might consider spending a bit more $$ and get a pro audio amp. This could provide you with more power, two channels of amplified power and have more flexibility for future sub projects - if that's your interest.
Finally, using a car sub for home use can be an O.K. thing. Keep in mind that all car subs will not be perfect. However, those with parameters that match more closely to home use are.
With that being said, I'm working on a few "test" enclosures where I'm using a 10" car driver and shortly a 12" car driver. Also, keep in mind that the Adire Audio 12" Shiva driver has a very dedicated following for home theater users. But, there are plenty of car audio enthusiasts running this driver in the trunks of their cars, too. It's a "two-way" street - no pun intended.
Enjoy !
