Soundcraftsmen Amp help

Hey all! Noob question here. I just picked up a Soundcraftsmen 300X4 amp. This is a 4 channel amp, but I’ll just be using 2 channels for a stereo setup (left and right). The speaker connections are labeled A, B, C, D. No mention of left/right. Would I connect my left Speaker to A, and right Speaker to B. Or Left speaker to A, and right Speaker to C. Here’s a pic...

I assume:
A is front left
B is rear left
C is front right
Dis rear right

is that correct?
