Page 7 Standard installation in undefined door volumes This form of installation is unsatisfactory and should only be used as a provisional arrangement, since it does not allow optimum Qts-factor. Moreover, holes in the door or leakage in the cladding may cause parasitic reflexions and impair the reproduction at low frequencies.
Page 8 Door Installation: In order to achieve optimal frontstaging, the tweeters should not be placed too deeply in the door area. They should be installed, for instance, at shoulder height and as far forward as possible, in the vicinity of the instrument panel. Suitable installation positions here are the side view mirror area and the upper door lining. Placing the tweeters on diagonal spacer rings (about 20°) can be tonally advantageous, if thereby the arrangement is done in such a way that the left tweeter radiates to the right door and/or right seat and the right tweeter radiates sound toward the left door and/or the left seat.

Installing and Attaching the Woofer Note: Do not attach via or puncture the membrane. Do not damage the membrane with a screwdriver or other sharp tool. • After selecting the installation location, attach the installation template at the designated location, e.g. with double-sided tape, amd mark the necessary drill holes and the space for the woofer.

around at least 6 dB quieter than on the front passenger side. For optimal positioning, a professional dealer, who can more accurately position the frequency response using specific measuring instruments, should be contacted. Note: It is important that all loudspeakers are correctly attached before start-up of the crossovers. If the crossovers are set into operation without the loudspeakers being hooked up, a very high current is produced on the unloaded LC-filters, which can, under the circumstances, destroy the coils! The jumpers of the crossovers must always be placed on the specified pins, according to the instructions.
Page 13 Connection of Woofer: Attach prepared loudspeaker cable (at least 2.5 mm²) at the screw connections „Woofer out” of the crossover (see fig. 9, No. 5), whereby the marked wire is connected with the positive terminal “+” and the unmarked wire with the minus connection “-“.
