I want to build my enclosure for my 2 shivas...and I know I need to put terminals on the box... I want to put terminals on 2 sides of the box so I can orient the box differently if I want to (without having wire trouble). My questions are.... do I need a terminal for each sub? is it ok to have 2 terminals wired up to each sub (for easier accesability if I want to turn the box around)? and WHAT kind of terminals should I buy and use?
