I have a '94 si, and the previous owner thought the best idea would be to get a secure housing installed for the deck to prevent robbery. Unfortunately this also means that I have no idea how to get into it. All I want to do is put in the wiring for an amp and maybe an aux input. It is an Alpine deck, if that makes a difference. I am pretty new to this, and running on a tight budget, so I was hoping someone might be able to throw me a few tips.
