I am planning on putting some speakers in the back of my 60, I don't want them to be down low in the back because I some times have cargo or in some 4x4 situations I've taken on water. So I want to mount them somehwhere up high possibly the roof or the back pillars on either side of the rear hatch. Has anyone here mounted speakers up high somewhere in the back? And if so do they have pics they could post?
