Kole Audio KMX Woofers
 
 
Congratulations on your purchase of one of the finest woofers available for your vehicle today. 
 
The KMX is designed for the serious SPL enthusiast. Our engineers developed a new finished aluminum dust 
cap to aid in thermal transfer and also help to lower the resonant frequency. The aluminum dust cap is direct-
coupled to the voice coil former, and serves to draw 50% of the heat away from the voice coil to the dust cap, 
thus acting as a voice coil heatsink. This “heatsink” action serves to maintain the strength of the bond between 
the cone and the voice coil by preventing adhesive breakdown due to thermal buildup. This revolutionary dust 
cap allows the woofer to handle 56% more power without sacrificing sensitivity. Your competition will never 
know what hit them. 
 
Please take a few moments to fill out the warranty card and review this manual before installing this woofer for 
proper connections and box sizes.
