I am hoping someone can help me on this. I have a custom sub box I made for my coupe and had the amp and everything installed but I removed it all and sold the coupe. Now I would like to install it into my sedan but I can't find the directions I used to figure out how to get RCA output to put into the amp or where to tap for the 12v trigger to turn the amp on.

Does anyone have wiring diagrams or details on what wires to tap to install a sub amp? Also I don't know what I need to connect the tap wires to the amp. In my coupe I used a Soundgate LOCX which does not appear to exist anymore.
