PA On Bike

Hey guys i was wondering if anyone know anyone that put a PA system on a bike?
I put the airhorn system on my ninja but i just got a new ducati 1198 and want to put something a bit smaller and i think a PA system called the Whelen from hornblasters will work since its size contraints are alot smaller.

Any one have any suggestions for me?
or
should i just go for it like i did on the ninja?

HAHAH GO FOR IT LIKE THE NINJAA!!! put horns on it! they have the next kit if u cant fit 4 horns u can do 2

Both maybe? If that would fit, it quit possibly might be the most ballinist s**t ever. If you could only fit one though, I would go for the horns. You know…it might save your life one day.
