might be better if you can refer to Combat mechanic section for setup

but in general, the setup for double attack is

2 Red gun + Auxiliary equipment (e.g radar, turbine, special ammunition, pure AA equipment(green), and mini-sub)   (12.7cm Twin High-Angle Cannon is a non pure AA)

1 Red Gun + 1 Yellow Gun + Aux Equip / Pure AA only

2 Yellow Gun + Aux Equip / Pure AA only

and 2 Midget sub (Type A Ko Hyoteki "甲標的 甲") is not good for a Sub setting ( Only good till the Sub chan is level 10 for opening torpedo)

Put 2 Torpedo on the sub instead to enable her do Cut in Effect (Sub can only do Cut in)
