The Dodge Magnum rear deck lid accommodates a 6x9 inch speaker size, fitting units in that location. Compatible types for that location include full-range speakers. These specifications cover the 2008 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 rear deck lid is a horizontal surface located at the rearmost section of the cabin, typically positioned beneath the rear window, which affects how sound projects into the passenger space.
Mounting in a rear deck lid position places speakers in a reflective acoustic environment, where sound bounces off the rear windshield glass and travels forward toward passengers.
A 6x9 inch speaker has an oval footprint with a longer axis of 9 inches and a shorter axis of 6 inches, requiring an appropriately sized cutout and sufficient depth clearance within the deck lid cavity.
The elongated oval shape of a 6x9 inch driver increases cone surface area relative to a circular speaker, which allows for greater air displacement and stronger low-frequency output in a rear deck mounting position.
The 2008 Dodge Magnum rear deck lid accommodates a 6x9 inch full-range speaker, a compatibility pairing relevant to fitment depth and baffle dimensions in that location.
Full-range speakers are designed to reproduce a broad portion of the audible frequency spectrum - typically from around 60 Hz to 20,000 Hz - through a single driver rather than relying on separate woofers and tweeters.
In a rear deck lid location, a full-range driver handles both low-frequency warmth and upper-frequency detail without requiring a crossover network or additional components in the same mounting space.
The mass and excursion characteristics of a 6x9 inch full-range driver allow low-mid and bass frequencies to carry forward from the rear deck position through the cabin.
Rear deck lid installations are generally subject to road vibration transferred through the vehicle body, which influences how a speaker's mounting frame and surround material interact with the enclosure surface over time.
