Hey, so as this is my first DIY sub for my first home theater system my expectations aren't too high. I have three old Bose 601 subs. With their cross overs. Some questions: 1) I plan on putting all three subs in the same box, is this cool? 2) I only have two cross overs so can I wire two subs to the one cross over? 3) In a rectangular box, where would be the best place to put the subs? Right now there are holes for two one at a 45 angle on the top, one 3/4 of the way down on the front side.... I don't think that there is room for the second on the front. 4) Can or should I buy cross overs and set each sub to a different level of Hz? How much will this cost me? 5) Do I have ANY idea what I am talking about? Thanks for the help guys!
