Installation Warnings
and Tips
and Tips
• Be careful not to cut or drill
into fuel tanks, fuel lines, brake
or hydraulic lines, vacuum lines
or electrical wiring when work-
ing on your vehicle. Inspect
behind panels before you cut or
drill.
• Make sure that the midwoofer
will physically fit in the mount-
ing location. If door mounting,
check for adequate clearance
with the window in both rolled-up
and rolled-down positions as well
as for interference with window
crank and power window mecha-
nism. If mounting elsewhere,
check for clearance around rear
deck torsion bars, glove box or
other structural elements.
• Do not mount speakers where
water may splash on the cones.
• Make sure that it will be easy to
run connecting wires to the
speakers. Trace speaker wire
paths before you undertake
mounting.
• Always disconnect the ground
wire from the battery before
doing any work on the vehicle.
CAUTION: Fuel tanks are
located directly beneath the rear
deck in some cars. Check for
adequate speaker basket clear-
ance before considering this
location!
