The Mazda CX-9 rear location accommodates a 6x8 inch speaker size, with all listed configurations supporting 6x8 inch units. Full-range types are compatible with the audio system at the rear position. The specifications cover a range of years from 2007 to 2009.
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 rear speaker location in the Mazda CX-9 accommodates a 6x8 inch mounting opening across the 2007, 2008, and 2009 model years.
A 6x8 inch speaker uses an oval footprint, which allows a larger cone surface area than a standard round speaker of similar height, increasing air displacement within the rear cabin space.
The rear location in a vehicle typically places speakers within door panels, rear decks, or side panels, meaning the driver and passengers receive sound from behind or to the sides, influencing the perceived stereo soundstage.
The 6x8 inch dimensions require a mounting depth and cutout width that must be verified against the rear panel cavity of the Mazda CX-9 to ensure physical clearance for the speaker basket and magnet assembly.
Full-range speakers are designed to reproduce low, mid, and high frequencies from a single driver unit, covering the audible spectrum without requiring a separate tweeter or subwoofer in the same location.
In a rear installation, full-range drivers handle bass frequencies that benefit from the larger cone area of the 6x8 inch format, as greater cone surface area moves more air to produce lower frequencies at comparable output levels.
The oval shape of a 6x8 inch driver affects its directional dispersion pattern differently than a circular cone, with the longer axis tending to produce a narrower horizontal dispersion at higher frequencies.
Full-range compatibility in the rear position indicates the location is not designated exclusively for a subwoofer or tweeter, meaning the single driver handles the full audio signal routed to that channel.
