The process of tweaking is going to be, for most relatively inexperienced subwoofer purchasers, a rather lengthy affair.
The basics one should follow should be ...
1. Make sure your subwoofer is calibrated properly to the mains in your system. An SPL meter is probably the most important tool for achieving this.
Most people opt for the Radio Shack meter.
2. Carefully read the receiver manual along with the subwoofer manual for set up.
For example, you want to make sure you set (in almost all cases) all speakers to "small" and the crossover to 80 Hz.
Use the test tone from the receiver - or better yet, from a disc such as Avia, to set proper phasing and SPL levels between the mains and the subwoofer.
3. Outside this, there are a lot of issues to look at - depending on Budget, decor, and listening preferences.
Audessey EQ, or another auto EQ in one's receiver
To answer your question - no, there isn't a simple "123" answer - but if you start with the first two listed above, the rest will get easier.
