It can't be done with only 4 channels of amplification and a system requiring 6 channels....unless you are planning to use the two pairs of DQ10's in a stacked configuration. Why do you want to use 4 main speakers in a two channel system???
How to Hook Up 4 Dq-10 speakers
I recently acquired a 2nd set of DQ-10s to add into my system of 2 DQ-10s, 2 DQ-1Ws, DQ-LP1, 2 Tandberg Amps plenty of power), 1 Tandberg Controller. I've heard of some who use only 2 amps to do this. I don't know how to hook up my additional 2 DQ10s using only the 2 amps and the electronic crossover; can anyone guide me in this? I see in the crossover manual that it is made to hook up 4 subwoofers with it, but states therein that you need 2 amps just for the subwoofers. Any guidance would be greatly appreciated.
