The process varies for each but if you follow the instruction manual, you will find it easy. There are quite a few videos on YouTube that will help you as well.

2) What are passive and active subwoofers?

Active subwoofers come with an in-built amplifier. Passive ones need an external amplifier. They only have a subwoofer drive.

In the market, you will find sizes from 8 to 21 inches. The large ones are for commercial use. For car audio, 10 and 12-inch subwoofers are the ideal ones. Please remember that these are the outer measurements. 

Also, the size of the subwoofer doesn’t play much of a role in the output. The power matters more.
