Speaker: Description and Operation
SYSTEM OPERATION
The standard equipment speaker system includes four speaker locations. The optional premium speaker system includes six speaker locations.
On four-speaker systems, one full-range speaker is located in each front door and one full-range speaker is located in each rear cab side panel. The
premium speaker option upgrades all the speakers to the Infinity bi-amplified models. Infinity coaxial speakers are mounted in the rear cab side
panels, and each front door has two separate Infinity speakers, a woofer and a tweeter.
Each Infinity woofer features an integral amplifier and frequency filter unit. The amplifier of the radio is used to drive the tweeters at each speaker
location. The speaker-mounted amplifiers drive the woofers at each speaker location.
