Trim Ring Thank you for purchasing JBL's Grand Touring Series multi-element automotive loudspeakers. We've organized this manual to make your installation as simple and trouble-free as possible. [. . . ] This will make each listener slightly off-axis to the tweeter that is closest to that listener, but on axis to the most distant speaker, which helps compensate for the fact that each listener is always closer to one speaker than to the other (see Figures 4a and 4b). Choosing mounting locations which satisfy all of the above criteria will provide the most satisfying performance. A Note on Power Handling As a result of their high efficiency, all JBL loudspeakers will produce reasonable volume levels in the automotive environment using very little amplifier power. However, the use of a small amplifier to attain very high volume levels could lead to overdriving the amplifier. This will generate high distortion levels which can easily damage loudspeakers, even if the rated power of the amplifier 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 amplifier or mechanical noise from an overstressed speaker. For the best performance and speaker reliability, you should select an amplifier with an output rating slightly higher than the maximum power likely to be used to generate the desired volume levels. This margin of reserve power will ensure that the amplifier will not attempt to deliver more power than its design allows. WARNING: Playing loud music over 120dB can permanently damage your hearing. The maximum volume levels achievable with JBL speakers combined with high power amplification may exceed safe levels for extended listening. When listening at high volume levels, always use hearing protection or turn it down! Aim Triangle of Tweeter Diffuser Toward Listener Installation Warnings and Tips · Be careful not to cut or drill into fuel tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on your vehicle. · Make sure that the speaker will physically fit in the mounting location. If door mounting, check for adequate clearance with the window in both closed and open positions as well as for interference with the window crank and power window mechanism.
