2.  Snap loose the driver’s side front and rear threshold panel along the bottom of the door openings. 
3.  Remove the red battery terminal cover and then the power distribution cover next to the battery on the 

passenger’s side. 

4.  Remove the fuse from the fuse holder on the amplifier and subwoofer power harnesses. Connect the ring 

terminals of both harnesses to the power lug identified in figure 1 and torque to 9 +/- 1.5 Nm.
