How can I open the case of the amplifier that my Mac Cube USB speakers plug into? - usb speakers

The cable from the USB cable to the amplifier are loose and I think it is a short inside the box. Sometimes I have terrible static on the speakers and must be separated. I want to see if there are naked son in the contact box.
