Hooking up two Rel Storm III's to Pass Labs X-350

I just purchased a Pass Labs X-350. Anything I should take into consideration before I hook a pair of Rel Storms to the Pass Stereo Amp in the normal Rel configuration for the unbalanced high level input. Both Red leads to the Right positive speaker post, both Yellows to the Left channel positive speaker post and both Black leads to the left negitive speaker post.
