I am getting ready to do my install and wanted to pre-wire everything before I headed down to the car to install everything. I am going to be installing the Pioneer DEH-M80MP HU, DCI Module, and the Pioneer I Pod Adaptor. Is it recommended to cut the wires to make them shorter? They seem rather long and I am not sure if their is enough room for everything to fit behind the deck. If cutting the wires is recommended, how short should I make them? I dont want to cut them so short that they dont fit and think that some slack is good. Worst comes to worse I could keep them all the stock length, but I would like to keep my install as tidy and slick as possible.
