Using one channel of an ICEpower 700as2?

I have some spare 700as2 modules that I would like to make use of. Ideally I would like each module to power one sub.

Can anyone confirm if I can use only one channel of the 700as2?

Each sub will receive one side of a stereo signal. It would be single ended input, single ended output. Just using one channel of each module start to finish.

Many thanks
