03 350Z audio upgrade help
 

I recently purchased 2003 Nissan 350Z, everything is working pretty fine except the audio system. So I am planning to replace the whole stock audio system. Currently I am looking at Pioneer AVH-P4200DVD head unit. I already purchased 2 new alpine type R speakers. I want to replace the stock sub with an aftermarket one in the same stock sub slot. Just wondering what will I need for a DIY installation?

All your inputs will be greatly appreciated.
