• Turn off the audio system. It is also
advisable to disconnect the negative (–)
terminal of your vehicle’s battery whenever
performing installation work.
• Before cutting, drilling or inserting any screw,
check clearances on both sides of the planned
mounting surface. Also check for any potential
obstacles, such as window tracks and motors,
wiring harnesses, etc. Check both sides of the
vehicle, many vehicles are not symmetrical!
• Always wear protective eyewear.
SPEAKER PLACEMENT CONSIDERATIONS
Grilles are not included with C1 speakers, as they
are designed for installation into OEM (factory)
speaker locations, located behind factory grilles.
Should you need grilles, you will need to purchase
aftermarket grilles separately.

Prolonged exposure to sound pressure levels in
excess of 100dB can cause permanent hearing
loss. These high-performance loudspeakers can
exceed this level. Please exercise restraint in their
operation in order to preserve your ability to enjoy
their fidelity.
