[. . . ] For the best performance and system reliability, you should select an amplifier 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 amplifier which has an RMS power rating equal to, but not exceeding, the Maximum Recommended Amplifier Power listed in the specifications of your specific JBL speaker. This margin of reserve power will ensure that the amplifier will not attempt to deliver more power than its design allows. Your dealer will be happy to point out which high power JBL amplifiers are 12 optimum for your application and listening habits. [. . . ]
