Hi, I have a Denon AVR5800 and an Atlantic Technology 10 inch sub and a Definitive PF1800 18 inch sub and would like to know the best way to hook these up. I currently only have the 10 inch sub hooked up to the sub out on my reciever but tommorrow I will be recieving the 18 inch sub. Can I just run the sub out from the reciver to the 10 inch then from the 10 inch using a Y adapter hook up the 18 inch sub? I really dont want to go back up into the attic to run another sub wire to the 18 inch if I dont have too. Thanks to all replies!!
