Jonathon - If you decide to go the SXT9 route, hit me up and I'll get you the flat mounts for the speakers. We've been seeing many RV'rs ask about taking their Exile speakers off their boats and mount them on the side of an RV or garage for that matter. It's pretty painless to do.

I wouldn't be worried about buying anything from Amazon in this day and age. Exile and WS are sold direct on amazon with factory approvals. I do think its a good idea to buy from a local shop if your going to have them install the gear.
