Wiring Configurations
There are a variety of impedance possibilities when using woofers equipped with
multiple coils. It is “EXTREMELY” important that ALL coils are used and none are left as
spares. Always provide the minimum impedance your amplifier requires. If you need
assistance with wiring configurations, please consult a professional installer or
contact our Technical Support Department with your questions.
