NOTE
: Make sure that your mounting location will not cause damage to the components of your vehicle.
Check for airbag system location, speaker can’t be located over or close it. Never play this component
without crossover, especially with high powers, this can damage it. Never play the system with amplifier
in clipping or high distortion level. If use a passive crossover, use a dedicated crossover system, don’t
use a generic passive crossover, these are not designed for this speaker impedance and the indicated
cut-off frequency may not be true.
