Welcome ritualrabbits 
Are you using a powered Profiler or a passive one? You'll need an amplifier in order for the preamp (= the Profiler) to be able to drive the cab.
Are the input and output LEDs on the Profiler lit when you strum? If not, check respectively the Clean Sens and the Master volume.
Let us know
PS: not related, but chances are the acoustic profiles you're using are acoustic simulators for electric guitars. Check the source!
I bet your acoustic has a hole in it. Check it and see. From what I've seen this is a widespread problem.
Howdy folks,
I've plugged Art & Lutherie acoustic to the Kemper and tried the acoustic profiles but I'm not getting any sound. I've got the Kemper attached to a 2x12 Orange Cab so just wondering what could be the issue. I've tried turning up the gain and volume a ton and that makes it barely audible, but then the sound gets all weird. Any thoughts?
If you do not have this problem with an electric guitar, check the battery in your acoustic guitar - it may need to be replaced.
You're welcome! I'm glad it turned out to be something simple

No. That hole is what helps acoustic guitars "amplify" the sound of the strings. 
Welcome! 
It happens to all of us...
