Dodge Challenger Rear Deck Lid Speaker Size

Additional Notes

• The rear deck lid of the Dodge Challenger is a horizontal surface mounted at the base of the rear window, above the trunk cavity, placing speakers in a position that fires upward toward the headliner and rear glass rather than directly toward the listening area.
• A deck lid location typically creates acoustic coupling with the trunk volume beneath, which can reinforce low-frequency output, making the cavity relevant to how woofers and midbass drivers behave in the 2016 and 2017 Challenger installations.
• The 8-inch woofer size listed for 2016 and 2017 models occupies a larger cone area, which allows for greater excursion and output in the lower frequency bands, generally covering the range below approximately 200 Hz and reinforcing bass reproduction from the rear deck position.
• Woofer-type drivers are dedicated low-frequency transducers without a tweeter element, meaning the 8-inch woofer entries for 2016 and 2017 indicate a configuration where a separate driver handles mid and high frequencies in a multi-driver arrangement at the rear deck.
• The 6.5-inch size appearing across 2016, 2017, and 2018 models is a common mid-size driver diameter suited to a frequency range spanning roughly 60 Hz to 5 kHz, making midbass and full-range types acoustically appropriate for the rear deck environment where both midrange presence and some bass extension are expected.
• Midbass drivers in the 6.5-inch format, such as those compatible with the Dodge Challenger rear deck lid in 2016-2018, are optimized for the lower midrange and upper bass region, typically operating below the range where a tweeter would take over in a component speaker system.
• Full-range drivers are designed to reproduce the audible spectrum from low bass through high frequencies within a single cone, and the 6.5-inch full-range compatibility listed across multiple years reflects the use of a single driver to cover the entire frequency range at the rear deck location.
• The 3.5-inch size listed for 2016 and 2017 is a small-diameter driver with a limited low-frequency response, generally effective from around 150 Hz upward, and at the rear deck lid location, a driver of 3.5 inches serves primarily as a supplemental full-range unit rather than a bass contributor.
• Full-range compatibility for the 3.5-inch entries in 2016 and 2017 reflects the type's ability to reproduce a wide frequency span, though the small cone area of a 3.5-inch driver constrains output and extension at lower frequencies, particularly when mounted on a flat deck surface with limited rear enclosure depth.
• The 6x9-inch oval format listed for the 2015 Challenger rear deck lid uses an elongated cone geometry that allows a larger radiating area within a constrained vertical depth, a property relevant to deck lid installations where vertical clearance is limited but horizontal space is available.
• A 6x9-inch full-range driver covers bass, midrange, and high-frequency content from a single driver, and the oval shape at a rear deck location positions the longer axis of the cone to maximize low-frequency displacement while fitting within the available mounting cutout.
• The 5.25-inch size listed for 2008 through 2014 models is a mid-size driver diameter with a frequency range typically spanning from approximately 80 Hz to 4 kHz, positioning midbass and full-range types as acoustically compatible choices for rear deck lid mounting in the Dodge Challenger during those model years.
