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.
