Thanks everyone for the replies. I actually got it for a pretty good price, about $20k.
For my sound system I got the stock system but with the Tweeter Kit. I just was considering trying to get a sub though I need some time to really get a feel for it. I just didn't know if the stock sound system even had a connector so I could hook up my own sub easily without replacing the head unit. I guess if I decide I want a sub that it'll have to go that route.
I'll check out the clear bra very soon, it seems like a pretty good idea.
I had heard a few of those things to check at the dealership but not all so thanks for the tips. This is my first Subaru and I am really looking forward to it.
