Kicker DX125.2 DX300.2 Manual Do Utilizador

Mounting: Choose a structurally sound location to mount your KICKER amplifi er. Make sure there are no items 
behind the area where the screws will be driven. Choose a location that allows at least 4” (10cm) of open 
ventilation for the amplifi er. If possible, mount the amplifi er in the climate-controlled passenger compartment. Drill 
four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the amplifi er.

Wiring: Disconnect the vehicle’s battery to avoid an electrical short. Then, connect the ground wire to the 
amplifi er. Make the ground wire short, 24” (60cm) or less, and connect it to a paint-and-corrosion-free, solid, 
metal area of the vehicle’s chassis. Adding an additional ground wire of this same gauge (or larger) between the 
battery’s negative post and the vehicle chassis is recommended.
