yep..lose the center speaker. totally not needed.
If your shop is not using The ZEN A2B device ($450) as part of your build, run away. You can't use high level input.
@dhmcfadin is 100% correct and he, and I and others have tried many times to educate people on this board.
The B&O systems uses the factory "sony" amp and hardware and applies a DSP to it. The problem is, as the volume is turned up, the B&O DSP removes bass to try and protect the speakers. So no matter how much power or how big of speakers you throw at it, the B&O amp and DSP are why the systems sounds great at low volume, but also what it sounds so bad when you turn it up. you HAVE to remove it.
to adress the volume concerns....that was my main gaol as well. Replacing the factory amp and speakers in the doors and A pillar + 2 sub woofers 10s or 12's is more then enough.
I can cruise 85mph with the windows down and roof open and hear and feel my music.
Also, dont focus on "wattage" of what ever speakers you are buying. it is the most mis understoof measurement on speakers that doesnt mean what most people think it means. Just make sure you have 4x75-125 watt amp for your doors and pillars, and 400-600 watts for your 2 subs and you will be fine.
my build is a no frills build that gives a great bang for your buck without breaking the bank. Assuming you can do it all yourself. If you cant, add about $1,000 or so labor.
