Car audio boxes are not going to work in a home audio box... pretty much never.
There are some excellent car audio woofers out there, of which JL W7s, Soundsplinter, and Infinity Kappas are some popular examples.
You will need to make a box yourself, properly modeled for a room application, not a car application. It will need to be more well-braced than what you get from car audio prefab.
Additionally, to ensure proper power handling and driver protection, you will need a high pass filter for most ported speakers.
If you're interested in DIY, I recommend it. But it actually needs to be DIY... pre fab will likely be a waste of time.
