I do think that looks like a good spot for one speaker... Not sure if I'll do another somewhere. I also think the idea of having them be some what removeable sounds good too. I have a few things I add everytime she comes out with us during the day (ladder, lounger type chair, and now maybe speakers). I do plan to keep this rig for some time, so maybe the big ol' hole isn't such a bad idea. I also worry about little bit about having that radio/cd player drain my starting battery.
