I just bought the 2009 WRX Sport Wagon "Premium". As with many others I want to upgrade the audio.
1. Is the antenna mounted on the roof (the small black stubby one) just for the
AM/FM, or is this an XM antenna as well? If so, any way to tap into it?
2. Do you know how many watts the stock "10 speaker" audio system head has?
3. I've been looking for replacement door speakers, I read here that there are some issues with mounting depth -- Polk as a pair with just over 2 inches depth, anyone know if 2 inches is too much?
4. In general on the forums I see good tips for speakers, installs, etc, but a lot of time people don't list their car year, or it is for 2007. Is everything the same on multiple model years, or are the 2009's different?
