16' Series speaker location

best place to locate speaker inside expanda front and rear

Pretty well where you can wire it easy. They can be in the roof depending on model, one in front of door in the ceiling (central)and one down the other end. They are wired during construction so its going to be hard to retro fit. What model van do you have? Poptop or full van? Some have them down low, maybe look at storage area under each bed end? Good luck, nothings impossible in an expanda.
Have you thought of a Bluetooth wireless speaker?
