How do you turn on the JBL subwoofer System?

[Lee Vining]

We spent time and effort, read the user's book, no directions and we’ve tried every trick. Thanks for any takes;

You can't trun on the subwoofers because there are no subwoofers! You have to install them separate and the plug them into the system. If pull the radio out you will see the connections for the subwoofers. I'm pretty sure there labeled.

Having the same issue in my 2024 Lance 2445. The JBL Nano subwoofer comes “installed” from the factory, but they installed it as though the head unit is, in fact, JBL. Although labeled JBL, it’s an aftermarket made for campers and other rec vehicles. You’ll need to pull the subwoofer and connect the blue line to the REM out line in the head unit.
