Crown XLi 800 Power Amplifier Review

ummm... because that's the way we mounted them?
EDIT: ahem.
Nope, not defensive.
They're Peavey Sanctuary Series and Peavey sez (or at least strongly implies) they can be mounted other way. They wouldn't lie, would they?

As I understand the manual they should be mounted vertical.

Should? That depends on the pattern one needs. Looking at the radiation patterns for these Peavey cabinets suggests enough symmetry that orientation probably doesn't make much difference.

At my church, I chose JBL CBA-50 speakers that comprise five 2" drivers in a phased line array. These specifically provide a wide horizontal pattern but a pancake vertical pattern. The pancake is designed to float over the microphones and first several rows of the church (that don't need sound reinforcement) to provide reinforcement to the back of the church while minimizing ceiling reflections. Those need to be vertical in most applications.

Looking at the specs for this amp they rated bridge 8ohm but not 4ohm.
You guys think that means, trying bridge 4ohms will be a VERY BAD idea?

Yes, if you need more power than the non bridged amp can deliver into a 4 Ohm load (the reason to use bridged mode in the first place).
