HT6 and four Rev 8's

To make a long story short, I have the following equipment in my boat:


Syn Micro powering a SS10B sub
6 cabing speakers, XS 650's
4 Rev 8's on the tower
2 HT6 amps to power the interior and tower speakers

I was thinking of using one HT6 to power the interiors and one HT6 (bridged) to power the four Rev 8's..... this way I can use the head units fade control to control the volume in the cabin vs the tower.

Should I be doing something different? Previously mentioned to me was to run a pair of Revs off of each Amp and some of the cabin speakers. In doing this I will loose the ability to control the volume level control so I will probably need to add a 420 eq.

Any help would be appreciated....
