I'm adding a 10 inch sub and amp to my SYNC 3 system. I have all the parts needed to build the resistor bank or board that I've read about in all of your posts. However, I have not found any instructions on how to put all the parts together. I'd like to get everything installed this weekend. I already have the power cable ran to the trunk and my ground cable set up. Just need to wire in my LC7I, amp, and throw in the sub. Does anyone have step by step plans on how to build this board so I don't fry anything? Thanks! :question:

Thanks! I'm curious why everyone says that I need to add a resistor if I unplug any speakers from the amp? So, if I unplug my factory sub and throw my replacement sub and amp it'll work fine?

Yup, removing just the sub or the center don't cause enough of a load drop to hurt anything. Once you start pulling the door speakers off, thats when you need the load resistors.
