A speaker's wire plugs are generally red (positive) and black (negative). Red wires connect to red plugs, and black wires connect to black plugs. If a speaker's wires contain different colors, the wires should be matched to their plugs by their positive and negative symbols. Full Answer >.
Finding wall studs. Wall studs in modern homes are spaced 16 inches on center -- that is thedistance from the center of one wall stud to the center of the next is 16inches. In older homes, studs may be 24 inches apart, or spaced irregularly.
Nail lumber sections to the stud wall to brace it in place. Check the studs with a carpenter's level to make sure the wall is straight. Step 3. Drill 3/8-inch holes through the bottom plate (the lumber section that runs along the bottom of the stud wall) between each stud. You will insert the anchors through these holes. Most building codes require anchors every 32 inches, but you can place them every 16 inches for added stability.
