I replaced the stock deck with an Alpine 9835. I used a Metra 70-5519 harness. It works perfectly. No noise issues at all. I did run new speaker wire from my head unit to the front woofers. I did this because my deck has an active crossover in it, meaning I can adjust the crossover frequency's and levels for the tweeters, mids and subs. It sounds better but the stock speakers aren't very good. I will be replacing them in the near future. If you are wanting to change the deck and dont have a active crossover deck then you will need some bass blockers or you might blow the tweeters. Here is a pic.
