Hi all and festive greetings, I am pondering something and i wonder if a few of you more electronically minded people out there can help. I have a Denon 3801 driving my seven speakers and my sub. I want to know if its possible to add 2 more speakers to my ES/EX channels by simply twisting 2 sets of wires into my banana plugs at the speaker outputs on the back of the amp? Obviously im aware that i wont create extra channels but will this 4 speaker array at the back be possible? I'm not questioning what it will sound like that is something i will find out and if it sounds good then great, if not then hey at least i tried something new and tinkering is fun. What i really need to know is,is this safe to do? Alternatively is it possible to run the extra 2 speakers safely in a serial way ie daisy chained? Hope you can help and thanks in advance, Regards,John.
