Cab connection option advice please

[SeliBian22+]

Hi I'm new to cabinet s and amp heads always used combos until I bought the silverline deluxe head, there are two in puts on the back of the head and two inputs on the cabinet, so do I use both inputs on the head and use a cable from each into both inputs on the cabinet, or one input on the head and use a splitter for both inputs into the cabinet.
Any advice would be great as I want to utilise the stereo sound from the can.
Thanks for any advice.
