3. ARK GRAY MAXIMUM In this zone low distortion output and long term reliability will be compromised especially by an aggressive user Slightly more SPL will be gained by pushing the power into this zone but typically not more than 2dB compared to the light gray zone The closer you are to the black zone the higher the likelihood of driver failure Operate with caution 1000W BLACK WARRANTY VOID We do not recommend operating woofers at this level of power In this zone there is a very high probability that the driver will fail due to excessive heat and or mechanical stress Subwoofer drivers operated at these levels of power are NOT covered under warranty JL Audio offers an extensive line of high performance subwoofer drivers to fit a wide variety of enclosure and power applications When designing systems with our drivers it is very important to achieve a good power match between the subwoofer amplifier and the subwoofer driver s capabilities The power levels listed in the above chart represent continuous RMS amplifier power per woofer and assume that the user will regularly make full use of that power without drastically overdriving the amplifier s Make sure you factor system impedance and the total number of subwoofers into your calculations Adhering to these power recommendations will result in systems that are both reliable and enjoyable JL AUDIO LIMITED WARRANTY USA Automotive Subwoofer Components JLAUDIO warran
