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. Inspect behind panels before you cut or drill.

•Make sure that the midwoofer will physically ﬁt in the mounting location. If door mounting, check for adequate clearance with the window in both rolled-up and rolled-down positions as well as for interference with window crank and power window mechanism. If mounting elsewhere, check for clearance around rear deck torsion bars, glove box or other structural elements.

•Do not mount speakers where water may splash on the cones.

•Make sure that it will be easy to run connecting wires to the speakers. Trace speaker wire paths before you undertake mounting.

•Always disconnect the ground wire from the battery before doing any work on the vehicle.

CAUTION: Fuel tanks are located directly beneath the rear deck in some cars. Check for adequate speaker basket clearance before considering this location!

A Note on Power Handling

As a result of their high efﬁciency, all JBL loudspeakers will produce reasonable vol- ume levels in the automotive environ- ment using very little ampliﬁer power. However, the use of a small ampliﬁer to attain very high volume levels could lead to over-driving 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 vol- ume 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 system reli- ability, you should select an ampliﬁer with an output rating greater than the maximum power likely to be used to gen- erate 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 ampli- ﬁer 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 optimum for your application and listening habits. Following these guidelines will provide virtually distortion-free sound reproduc- tion 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 ampliﬁcation may exceed safe levels for extended listening. When listening at high volume levels, always use hearing protection or turn the volume down!
