6 by 9 speaker spacer

i designed this 6 by 9 speaker spacer cause my dad bought a new truck and he wanted to up grade the speakers in it, but there isn't much space in the door to for the bigger magnet so i came up with this.

its a spacer that's about 2 inch's tall and around 1.5 inch's tall on the other side. its in a 5 degree angle, so the speakers can point up.
