The Ford Ranger behind rear seat location accommodates 6 inch speaker size units, as well as 6x8 inch, 10 inch, and 5x7 inch speakers across the model's production range. Compatible audio types for the rear location include subwoofer and full-range replacement system configurations. These specifications cover a range from 2000 to 2025.
A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers.
Full-Range
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-rear-seat location in the Ford Ranger positions speakers in an enclosed cavity between the rear seatback and the cargo or cab wall, a space that typically limits enclosure depth and affects low-frequency reinforcement due to restricted air volume.
A 6-inch subwoofer installed behind the rear seat operates within a compact footprint while targeting bass and sub-bass frequencies, generally reproducing content below approximately 200 Hz, where directionality is low and placement relative to the listener is less acoustically critical.
The 6x8-inch oval format accommodates a wider cone surface area within a constrained vertical height, allowing more low-midrange output than a smaller circular driver while still fitting within the shallow behind-seat cavity of the Ranger.
Full-range drivers, such as those specified in the 6x8-inch positions, are designed to reproduce a broad frequency band spanning from bass through treble within a single driver, making the location function as a self-contained sound source rather than a dedicated low-frequency unit.
The 5x7-inch oval specified for the 2000 and 2001 Ford Ranger behind-rear-seat location is slightly smaller in cone area than the 6x8-inch format, a difference that affects the lower boundary of effective bass reproduction and the overall volume displacement of the driver at that position.
A 10-inch subwoofer at the behind-rear-seat location produces significantly greater cone area and excursion potential compared to the 6-inch subwoofer, resulting in deeper bass extension and higher output at low frequencies, typically reaching below 80 Hz with greater efficiency.
The Ford Ranger behind-rear-seat location accepts a 10-inch subwoofer only in the 2004, 2005, and 2006 model years, indicating a larger enclosure or mounting recess was present in the cab design of those vehicles.
Subwoofers as a speaker type are designed exclusively for low-frequency reproduction and are acoustically non-directional in the frequency range they cover, meaning the behind-seat placement does not create significant imaging issues for bass content in the cabin.
The transition from 5x7-inch full-range drivers in the 2000-2001 Ranger to 6x8-inch full-range drivers in the 2002-2012 Ranger reflects a change in the physical mounting dimensions of the behind-rear-seat location across those generations.
The 6x8-inch and 5x7-inch oval formats are acoustically compatible with the same mounting cutouts in many cases due to their similar outer dimensions, but the specified sizes for the Ford Ranger behind-rear-seat position are listed distinctly across model years, indicating model-specific fitment requirements.
Full-range drivers at the behind-rear-seat position contribute midrange and high-frequency content to the rear cabin, though the location behind the seatback introduces acoustic shadowing that attenuates high-frequency output reaching front-seat occupants.
The simultaneous listing of a 6x8-inch full-range and a 10-inch subwoofer for the 2004, 2005, and 2006 model years indicates the behind-rear-seat area in those Ranger configurations accommodated more than 1 distinct speaker mounting position.
