Preamp amp connections


Hello,
Is there a way using one revamp (Mac MX135) to connect to several amps?  I have a 7.1 set up and I want to run the Center, FR, FL and Sub off a Mac 7108 with all outputs bridged.  Then add another amp (TBD) to run the LS RS RB and LB.
Thanks for any advice you can give me.
