It stands for Akihabara 48. Akihabara is where they perform with about 48 band members that are divided into three groups called A, K, and B. They even have other city spinoffs, but I can't tell you who they are as I really don't follow these kinds of groups. I only know AKB48 as they were merchandised everywhere when I lived in Japan.
