How do I connect speaker wires to a Mc2002 amp?

Hi there, I am a newbie and I just purchased a MC2002 and it has on set of barrier strips with L C C R which are lug nuts for spade connectors. At each side of the barrier strip, there is a nut that looks like a ground. Can anyone help me with how to connect the speaker wires? I thought maybe there shoould have been two barrier strips but there is only one.

Appreciate your help.

Left speaker:

positive to L, negative to C (common)

Right speaker:

positive to R, negative to C

Thanks. I got it. Was strange seeing only one barrier strip.

Great amp.
