any cool ideas for starting a minidisco bar business?

the bar is located on the 2nd floor of a minimall with the size of only 30 sq.m. & rectangular shaped. although a few meters away there's already a social bar with the size trippled as the size of what i have, but the rent seems to be reasonable and i will be playing cool trance, techno etc. music from amsterdam and i will put up my business here in the Philippines somewhere around visayas, do you happen to know how many speakers should i need? etc. etc. please advice me....
