HI everyone! I just signed off on a 2006 WRX limited! I can't wait to get it and I want to thank everyone here for being so welcoming and helpful to answer questions. Much better than other forums. Anyhow, I have a question. My car is coming with three 'extras'. One is the sub/amplifer, another is the boost gauge, and the third is armrest extenstions? Are these standard for the WRX? WRX limited package? Are they an extra feature? Are they worth getting or should I ask for something else/ask they be removed? If anyone can explain this or even better, has pictures, that would be great. It probably seems like a rookie question, but then again, I am one! Thanks again!
