I couldn’t sleep last night and finally realized why. In all my planning for the audio system, I seem to have left out connectors for half the speakers. I planned for one wire for left and one wire for right. Obviously there are two wires for right and two for left. That means I need to order more connectors from DeepSurplus and goto Home Depot to get some more low voltage boxes. I feel like such an idiot; this project probably would get done much faster and correct the first time if I hired a professional, but then I wouldn’t get the joy of knowing I did most of the work myself.
