"ghetto boom" is easy to reproduce in my (limited) experience. Techno and house is harder because it distorts easily, whereas the typical suburban wigger massive american car stereo bass just wobbles smoothly even on crap subs.

Get your self a couple of 12 inch subs and an amp and you'll probably be happy. I think most 12 inch subs go down to around 25 hz, but I couldnt tell you what 25 hz sounds like.

Its worth reading up on wiring, so you dont destroy your amp.
