I just bought my home theater setup 4 m22s, svs 25-31 pci, and an HK 525 and i had some questions.

For how long should i break it in?
What volume should i break it in at?
Are there any safety mechanisms on either the reciever or the sub?
How do i prevent the sub from bottoming out?
How do i prevent the reciever from breaking?
I own LOTR 1 and 2. What scenes should i test/listen to on those movies?
Is the reference level 75 or 85 dbs?
Finally, can i leave the system on all day long without ever turning it off? including sub and reciever?
