I have purchased four Chane Home Theater CHT 18.1 subs and I was wondering if I should buy a new MQ-600 or two used Dayton SA-1000 amps? Someone is selling the Dayton's used. I kinda like the ability to split the subs up into pairs of two and placing in different rooms if my needs change down the road. What do you all think? But to start with, I'll be using all 4 subs in one room.
