Hi all this will be my first post on this forum. I have been a long time reader here. I have a 12'W x 20'L concrete block detached garage. It has no interior framing accept the trusses which are built old school perfect pyramid so I have many options as far as proposed interior room hight. There is no electricity to it so basically I have a bare bones room to start with. I have been planning on developing this into a Theater room for years now and have finally started buy digging a trench and running conduit for the future electrical which will be my first step. So question at hand. If you were starting from scratch in this stuation how many breakers and what amperage would you use for your power. I will be using 3 B&K ST140 amp's, Panisonic Rp91 DVD player, and a B&K ref.20 processor pre amp, 3 klipsch fortes for LCR and Klipsch KG2's for suround and rear and 2 Klipsh SW12's. The projector will be determined latter but it will be a DLP or LCD. I intend to also have at least 1 butkicker shaker, lighting with dimmers, an alarm system and im sure Im missing several other items. I just want to get off on the right step and this is my first one after the internal framing which is a diff. issue. Thanks for any help you can provide.
