A Note on Power Handling
As a result of their high ef�ciency, all JBL loudspeakers will produce reasonable volume levels in the automotive environment using very little ampli�er power. However, the use of a small ampli�er to attain very high volume levels could lead to overdriving the ampli�er. This will generate high distortion levels which can easily damage loudspeakers, even if the rated power of the ampli�er is below the rated maximum power handling of the loudspeaker!

As a general rule, do not turn up the volume control past the point where you hear distortion in the form of either signal distortion from an overdriven ampli�er or mechanical noise from an overstressed speaker. For the best performance and system reliability, you should select an ampli�er with an output rating greater than the maximum power likely to be used to generate the desired volume levels.

If you want your system �Loud + Clear,� we suggest that you step up to a JBL power ampli�er which has an RMS power rating equal to, but not exceeding the Maximum Recommended Ampli�er Power listed in the speci�cations of your speci�c JBL speaker. This margin of reserve power will ensure that the ampli�er will not attempt to deliver more power than its design allows. Your dealer will be happy to point out which high power JBL ampli�ers are optimum for your application and listening habits. Following these guidelines will provide virtually distortion-free sound reproduction and long loudspeaker life.

WARNING: Playing loud music over 120dB can permanently damage your hearing. The maximum volume levels achievable with JBL components and high power ampli�cation may exceed safe levels for extended listening. When listening at high volume levels, always use hearing protection or turn it down!
