Sound of the radio in the Civic FK/FN

I would like to get some opinions about the serial speakers and the radio in the current Civic. Supposedly this is not supposed to be so awesome. I like to hear House, Techno and very important: Drums Bass. How much can one demand the boxes? Can one possibly connect a power amplifier to the Civic radio or does it have a preamplifier output? And what does the premium speaker set in the accessories of Honda bring?
