I have rf7s as my mains and using B&K 200.2 amp, 2 channel and denon 3802 as a preamp. I am getting a B&K 200.5 5 channel amp and want to biamp the rf7s. the 3 channels on the amp will be running the center and the 2 surrounds and the remaining 2 channels on this amp and the 2 channels on my 200.2 will be used to biamp. the interconnects on the 200.2 is going to the preouts on the denon, where do i connect the interconnects of the other 2 channels i am using as the biamp. the denon only has preout for the main R and main L , center, surrounds
also would it make a difference if i am using 2 different brand amps to biamp the speakers B&k 200.2 and sunfire grand cinema would be the amps used
