Speakers

The standard (UX8), and Bose (U57) audio systems each contain eight speakers. In the UX8 system, four speakers are contained in the doors. The doors each contain a full-range speaker. The A pillars each contain a tweeter and the rear package shelf contains a subwoofer speaker with two voice coils. The left door speakers, the left A pillar speaker, and the left subwoofer voice coil, are driven by the left channel audio circuitry. The right door speakers, the right A pillar speaker, and the right subwoofer voice coil, are driven by the right channel audio circuitry. The dash-mounted center instrument panel midrange speaker is driven by an output signal synthesized from the right and left signals. The Bose system (U57) is similar, except the subwoofer has only one voice coil. One channel (right or left) consists of low-power amplification in the radio of signals generated in the tuner, tape player, or in-dash CD player circuits. These signals are sent by the radio via dedicated audio lines to the radio amplifier. The radio amplifier processes the signal (volume, tone, balance, fade) and provides the final power amplification that drives the speakers. If equipped with a CD changer, the CD changer circuit contains low power amplification and audio lines, similar to those in the radio. The CD outputs are connected to unique, separate input circuits in the radio amplifier, which process the CD signals in the same way as the radio signals are processed by their circuitry. Both of these sets of low-power circuitry feed one common set of output circuits, which provide power to the speakers.
