The Mazda B-Series Pickup behind seat location accommodates a 6x8 inch speaker size. Full-range units represent the compatible type available for audio system installation. These specifications apply to the 2000 model year.
A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems.
Additional Notes
The behind-seat location in a pickup cab places speakers in a constrained vertical space, typically mounted low and angled within the rear cab wall or panel behind the occupants.
Acoustic output from the behind-seat position projects forward toward the cabin occupants, though the rearward mounting angle can cause some high-frequency directionality loss relative to ear level.
A 6x8 inch driver covers a relatively broad surface area compared to round equivalents, which supports lower mid-bass reproduction within the limited enclosure depth available behind a pickup seat.
The oval geometry of a 6x8 inch speaker allows fitment in shallow or asymmetrical cavities where a circular driver of comparable cone area would not physically fit.
The Mazda B-Series Pickup behind-seat position is specified for 6x8 inch drivers in the 2000 model year, making frame diameter and depth clearance critical factors for physical compatibility.
Full-range speakers are designed to reproduce the full audible spectrum from a single driver, handling low-frequency fundamentals through high-frequency harmonics without a crossover or companion tweeter.
In a behind-seat application, a full-range driver must manage directional high-frequency content from a position that is not in the direct line of sight to the listener, which affects the perceived treble response at seated ear level.
The relatively large cone area of a 6x8 inch full-range driver in this position supports mid-bass frequencies that would otherwise require supplemental subwoofer reinforcement in small cab environments.
