Hey guys: I have a "newbie" question for you. How do you hook-up two or more subs? Do some recievers have multiple in-puts for subs? Or you hook them up in "series"? I know my current reciever (cheap Sony) only has one input for the sub. The reason I ask is because I am planning my HT and I am thinking of going with 2 or 4 of the modified Sony Subs instead of one SVS or HSU. I can get them for about $100/each. Thanks in advanced. Andy P.S. I am not so concerned about "get the SVS instead" comments. This is more of a general question. Or how do I run dual 25-31's if you like that question better?
