Speaker Install
54. Due to the A-pillar location, the stock speakers will not easily remount in their stock
location. Therefore we recommend replacing them with a 4” speaker. We provide
two options for mounting a 4” round speaker and it is up to the installer to decide
which option to use.
Option 1 features a behind the dash install using the 4” speaker
mounting brackets provided in the kit. (Steps 55-61 will cover this
option) **Note, this installation should be done now before
continuing.**
Option 2 is only really applicable on 2007-2010 models and
consists of a simple relocation to the door. (Steps 62-70 will cover
this option) **Note, this installation can be done at the end of the
install**
Behind Dash Install
