best way to mount my new horns?

hey guys just ordered the HornBlasters Conductor’s Special Model 240 Train Horn Kit and was wondering the best place to mount the horns to get the most sound? they are going on a 2006 chevy silverado crew cab z71…

thanks for your help!!

Anywhere except in the cab!
Really though, along the frame, spare tire location, behind the grill, wherever you can fit them.

Ok thanks man
