The Chrysler 300 rear location supports an 8 inch speaker size, as well as 6x9 inch units, accommodating varying speaker configurations across the model's production run. Compatible types within the audio system include subwoofers and full-range replacement units. These specifications cover the years 2008 through 2017.
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 rear speaker location in the Chrysler 300 accommodates 2 distinct speaker sizes across the listed model years: 8 inch and 6x9 inch.
An 8 inch subwoofer in a rear automotive location is positioned to take advantage of the cabin's enclosed volume, which reinforces low-frequency pressure buildup and enhances bass reproduction throughout the interior.
The 8 inch diameter gives a subwoofer sufficient cone surface area to move the air volume necessary for reproducing frequencies typically in the 20 Hz to 200 Hz range, making rear placement acoustically effective for low-end reinforcement.
A subwoofer is a single-purpose driver designed to reproduce only the lowest frequencies in an audio system, requiring a dedicated low-pass crossover signal to function within its intended range.
The Chrysler 300 rear location for 2008 accepts a 6x9 inch driver, which has an oval form factor that maximizes cone area within a constrained mounting depth - a common characteristic of rear deck placements in sedans.
A 6x9 inch full-range speaker covers a broad frequency spectrum, typically from around 50 Hz up to 20,000 Hz, allowing a single driver at the rear location to reproduce bass, midrange, and treble without supplementary components.
Full-range drivers in rear deck positions tend to exhibit wide vertical dispersion toward the passenger cabin ceiling, which affects how treble frequencies are reflected and perceived by rear and front occupants.
The transition from a 6x9 inch full-range driver in 2008 to an 8 inch subwoofer from 2009 onward indicates a change in the rear mounting cavity dimensions and audio system architecture in the Chrysler 300 between those model years.
An 8 inch subwoofer requires a mounting cutout and depth clearance suited to its circular frame, and rear deck installations must accommodate the driver's total depth, including the magnet assembly, without interference from the trunk cavity below.
Because a subwoofer handles only low frequencies, the Chrysler 300 rear location in the 2009 through 2017 model years is not designed to reproduce midrange or high-frequency content independently at that position.
