..... So they must be in series because it's a 12v device and these cells are 1.5V each.

The batteries are wired in serial. The spec's also state that with battery power the amp is limited to 10 watts /channel. While using a external power supply you will get 15 watts / channel. I definetly noticed a change in power when I switched from battery to power supply.
