Hi all i am thinking turning my subs around the other way so they face the back of my seats and was wondering if this would sound worse although it would protect the subs more? Any feed back would be good cheers.

Subs are not directional, they require a space to empty into to sound their best. Boots are good because the sound is amplified by the free space. Leave them as they are.

Plonking one in the middle will be fine but have the ski door and armrest down.

It actually will sound different, what most people find is that the subs facing the back of the seats won't be as loud however you may perceive it to sound better. Facing the subs towards the boot lid will give them more area to load off of and may actually come across as being louder.

Always mount your sub box to stop it from sliding around, every little bit helps and have fun experimenting.
