this is a 33.6 ft fifth wheel toyhauler, it has a Kewood touch screen, I have looked all over for a switch, but no luck, think I'm going to have to try the fader/balance controls. has a 500watt amp/kicker located on top of the cabinets. shows the outside speakers,, just no info on how to turn them on. :-(
is it a DDX24BT? If so or a similar model you'll need to look through the manual, the speakers should have been set up but if not you or the dealer will have too.
