thanks for your responces

In a car you have a nice helping factor called cabin gain that will emphasize the bass from even the cheapest subwoofer at around 50Hz.  Placement is less of an issue since the physical space available is so small.  In a room you do not have it quite so easy.  Corner placement, etc. can generate some room gain, but it is all about the size of the room and what else is sitting in it. and how the sub is positioned, not to mention how the enclosure is constructed to optimize the woofer's performance, how the amp is EQ'd, etc.  The reason good home subs cost so much more than car subs is not simply because of nice veneered cabinets!

The articles linked above are excellent resources, by the way.
