DON'T CHANGE THE STOCK DECK! No other aftermarket deck looks right in a Type-R. The amber lights don't match with any of the aftermarket decks (my opinon). If you bought the Type-R, you probably like the engine noises anyway. Here's the route I took:
CD Changer that plays Mp3's. No, it doesn't make your sounds louder, or more defined, but it does add functionality. What do you think? The stock deck is the only one that looks right lit up (once again, only my opinion).
