I have a spot in my basement for my home theater. It is 30 ft X 30 ft. With 9'6" ceilings. I have a garage stereo set up that I don't use much and would like to find out if I could use the components I have and purchase additional equipment to make it work in my home theater. Here is what I currently have: Speakers: (2) peavey sp2 (2) peavey sp218 Amps: (2) cs 4000 (1) pv 2600 (1) pv 2600 I have each of the cs4000 bridged into the sp 218, the pv 2600 running the horns in the sp2, pv 3800 running the 15 inch mids in the sp2. Could I purchase 2 more sp2 or equivalents and get my surround sound? How do I mix signals for home theater?
