06 530xi, I need more bass!

I find the bass to be lacking in my 530xi, after reading a few informative threads it looks like the Earthquake SWS-8 is a worthy replacement for the under the seat subs (not sure if I need 2ohm or 4ohm though), and what replacement amplifier(s) work? Where do you go for them? Are they plug'n play or a little bit more involved? I would like to avoid throwing a code. I was also contemplating just putting an external amp in the trunk for the two 8" subs. Any thoughts are greatly appreciated.
