I currently own a 990 and use it with a Monster 3250 and B&W 804S's.

My parents asked me to put together a system for them, so I just received the following gear:
1)990
2)7500
3)M80 V2
4)VP 150 Center
5)QS8's Surrounds
6)EP500 Sub

I know a lot of people on the forum are running similar setups and, before I hook everything up, I just wanted to ask if anyone has any general suggestions for this setup - specifically regarding crossovers, speaker placement, and sub settings.

I'm not very familiar with all of the sub settings, and there are a fair amount of options on the back of the EP500.

Thanks in advance for any suggestions.

Cheers.
