Audio System
AUDIO SYSTEM
The audio system on the 2003 PT consists of a radio that communicates over the PCI Bus. Each radio system comes equipped with a standard premium 6 speaker system.
The speakers are located in the instrument panel, the front doors and the rear "D" pillars. The instrument panel speakers are a tweeter type speaker for high frequency.
The front door speakers are a woofer/midrange type speaker. The rear "D" pillar speakers are a full range type speaker. If one of the speaker circuits experiences a short, the other speakers on that channel will also shut down until the circuit is repaired.
The radio will also set a trouble code, which the DRB III (R) can display.
