The factory inside and outside speakers on our 2010 Niagara, while useful to have, left a lot to be desired. We use it in the afternoons or evenings when getting ready for dinner, as well as some mornings; never loud enough for the neighbor(s) to hear the music, unless we are with them and they want to hear it. Before: For the outside, I had to drill out the rivets, and then assess what was behind the speakers. The walls were empty, so I used some polyester batting from an old pillow to fill it in a bit and improve the sound deadening. Also had a hard time finding the 3/16" rivets that had a grip range of ~1". Once I finally found them at a local Fastener business, they were ~ $.35 each! worked like a charm. I used butyl tape under each speaker, and then caulked around them when I re-caulked the roof. AFTER: (sorry for the poor angle) INSIDE, BEFORE: INSIDE, I had installed a set of Poly Planar 5" speakers that I had--the sound quality was poor in comparison to the 6.5" that it should have, so I picked up the Rockford Fosgate ones (see parts list below). Poly Planar ~5": Rockford Fosgate, AFTER: ' Parts Needed: Inside Speakers: Rockford Fosgate M2 M262 Marine Grade 6.5" Component Speakers_White http://www.amazon.com/Rockford-M262-6-5-Inch-Component-Speakers/dp/B001SPRNCO/ref=sr_1_1?ie=UTF8&qid=1377012094&sr=8-1&keywords=rockford+fosgate+6.5+marine#productDetails Outside Speakers: JBL MS6200 6.5" 2-way Marine Speakers.

Butyl tape for under the speakers to help seal between the camper body and the speakers. (~$5-$10 for a roll from your local RV dealer) Rivets: $3 Caulking: I caulked around the speakers afterwards, with the Sikaflex 221 that I was using on the roof edge seams. A tube of that costs about $13.
