When removing or installing the grilles, be careful not to brush the woofer's rubber surround or thetweeter's dome with the edge of the grille. Cutting or tearing the surround or dome will destroy the unit.Never run wires outside or beneath the vehicle where they can be snagged by road hazards or the movingparts of the vehicle. Use existing wire channels, sills, panels and molding strips inside the automobile tohide the wiring for neat appearance and safety.Make sure your radio/cassette/cd player and or other equipment is turned off while connecting thespeaker terminals. Turn on the various components and slowly advance the volume control ONLY afterchecking and double checking all connections.NOTE: If the sound is weak or distorted, immediately turn down the volume and see the section entitledTroubleshooting.installation planningProper installation planning is the best way to maximize performance. By planning your installationcarefully you can avoid situations where the performance or reliability of your system is compromised.Your authorized a/d/s/® dealer or a/d/s/® audio technical support at 1-800-753-0800 x2033 has beentrained to know how to maximize your speakers sonic potential. They are a valuable resource in helpingyou with your system design and installation.amplifier requirementsThis speaker system requires a minimum of 45 watts per channel to achieve reasonable listening volumesin a moving automobile without clipping the amplifier. a/d/s/® recommends 150 watts per channel as amaximum so as not to exceed the thermal or mechanical limitations of the speaker system. Any amplifierbetween 45 watts and 150 watts may be used. If you choose to use an amplifier with more than 150watts use caution as speaker damage may occur at high volume settings. All a/d/s/® loudspeakers willproduce reasonable volume levels in the automotive environment using moderate amplifier power.However, the use of a low powered amplifier to try and attain very high volume levels can lead tooverdriving the amplifier and damaging the speaker system. As a rule, do not turn the volume up abovethe point where you hear distortion on musical peaks from either an overdriven amplifier or mechanicalnoise from an overstressed speaker. For the best performance and reliability; select an amplifier withslightly more than the maximum power you are likely to need to generate the desired volume levels. Thismargin of reserve power will ensure that the amplifier will not be routinely driven beyond its design limits.WARNING: Excessive sound pressure level can permanently damage your hearing. The maximum volumelevels attainable with a/d/s/® speakers, combined with high-power amplification, may exceed safe levelsof extended listening.mounting locationsThere are many possible choices of mounting locations. The vehicle factory locations will usually dictatethe woofer mounting position. Because of its small size and multiple mounting options, the tweeter canvirtually go anywhere. a/d/s/® uses an unusually low crossover frequency for the tweeter which means youare not restricted to mounting the tweeter close to the midrange speaker. The tweeter can be mountedas far as 24" (60 cm) from the midrange speaker without causing adverse effects on the sound quality.However, better results are usually obtained by locating the tweeters and midranges relatively close toeach other, and by keeping the sound path lengths between the listener and the left and right speakersas equal as possible.a/d/s/® cannot recommend specific tweeter mounting locations for each vehicle, but in general try to keepthe tweeters as far to the sides of the car as practical. Avoid placing them above ear level unless thewoofers are also above ear level. Place the tweeters in similar locations on both sides of the vehicle. Try afew locations by just placing the tweeter or taping it in a location and listening to ensure the desiredstereo image and high frequency dispersion are achieved before committing to a location by drilling holesin the vehicle. You should also experiment with the tweeter phase switch settings to find the mosteffective combination of location and phase.3 |
