Audio System

WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

The Ranger is available with the following audio systems:

AM/FM
Premium AM/FM with single CD
Premium Dual Media-AM/FM with cassette and single CD (MP3 compatible)
Premium CDX6 - AM/FM with six CD in-dash (MP3 compatible)
CDX6 Audiophile - AM/FM with six CD in-dash (MP3 compatible) and a subwoofer powered by its own amplifier
TREMOR Audio - AM/FM with six CD in-dash (MP3 compatible). The TREMOR audio package consists of two front door mounted two-way speakers, two rear door/rear quarter panel mounted two-way speakers, and a subwoofer. All speakers are powered by the radio amplifier.

The audio unit can be powered up when the key is in the RUN or the ACC position. The smart junction box (SJB) supplies voltage to the audio unit through circuits 1002 (BK/PK) (hot in RUN/ACC) and 797 (LG/VT) (hot at all times). Voltage is supplied to the subwoofer amplifier in both CDX6 Audiophile and TREMOR audio systems by the battery junction box (BJB) through circuit 828 (VT/LB) (hot at all times). When the audio unit sends a voltage to the amplifier, through subwoofer amplifier enable circuit 829 (WH/VT), the amplifier is powered up. In the CDX6 audiophile the subwoofer amplifier powers the subwoofer only. In the TREMOR audio system the radio amplifier powers all of the speakers. The radio suppression equipment reduces interference transmitted through the radio speakers by the engine ignition and electrical systems.
