Additional Information; Example Of Installation On The Floor Mat Or Chassis - Pioneer GM-A6704 Manual De Instrucciones

Installation
! The optimal installation location differs de-
pending on the car model. Secure the ampli-
fier at a sufficiently rigid location.
! Check all connections and systems before
final installation.
! After installing the amplifier, confirm that the
spare tire, jack and tools can be easily re-
moved.
Example of installation on
the floor mat or chassis
1 Place the amplifier in the desired instal-
lation location.
Insert the supplied tapping screws (4 mm ×
18 mm) into the screw holes and push on the
screws with a screwdriver so they make an im-
print where the installation holes are to be lo-
cated.
2 Drill 2.5 mm diameter holes at the im-
prints either on the carpet or directly on
the chassis.
3 Install the amplifier with the use of
supplied tapping screws (4 mm × 18 mm).
