I'm setting up a whole house system and I need some help deciding how to best utilize the amps I have. I've got a total of 10 speakers to use. I was planing on putting four pioneer elite 8 in 6 ohm speakers in the ceiling of the living room. (S-1c871a). four s-1c691a pioneers in the master and one s-1c61a in the master bath and down the hall. I was going to use a paradigm volume control in the bath. The amps I have currently are 2 sonos zp120 one zp 90 and a niles si-1230. I was probably going to get one moe zp 90 to use with the niles. My question is what speakers to use with which amp and should I bridge the channels of the niles.
