Ram 1500 Overhead Speaker Size
The Ram 1500 overhead location accommodates a 2.5 inch speaker size across all listed model years. Midrange units are the compatible type for audio system replacement in the overhead position. These specifications cover the 2011 to 2017 chart of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midrange | 2.5 |
| 2016 | Midrange | 2.5 |
| 2015 | Midrange | 2.5 |
| 2014 | Midrange | 2.5 |
| 2013 | Midrange | 2.5 |
| 2012 | Midrange | 2.5 |
| 2011 | Midrange | 2.5 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The overhead location in the Ram 1500 positions speakers at the ceiling of the cabin, directing sound downward toward occupants across multiple seating rows.
- An overhead mounting position creates a wide, diffuse dispersion angle, as sound radiates broadly from above rather than from a focused point at ear level.
- The overhead location in a full-size pickup cabin like the Ram 1500 serves rear-cabin coverage, where door-mounted speakers may have reduced output due to distance from rear passengers.
- A 2.5 inch driver is a compact unit with a small cone surface area, which limits low-frequency excursion and reinforces the role of the location as a supplemental rather than primary acoustic position.
- The physical constraints of an overhead cavity in a truck headliner require a shallow mounting depth, and 2.5 inch drivers typically carry a low profile compatible with thin panel enclosures.
- A 2.5 inch midrange speaker in the Ram 1500 overhead position handles the frequency band roughly between 500 Hz and 5 kHz, which corresponds to vocal presence, speech intelligibility, and upper instrument harmonics.
- Midrange drivers are designed with cone and surround materials optimized for the middle portion of the audible spectrum, avoiding the excursion demands of woofers and the stiffness requirements of tweeters.
- At 2.5 inches, the driver diameter produces a relatively narrow effective wavelength range, keeping the speaker well within the midrange band and preventing high-frequency beaming or low-frequency distortion.
- The overhead placement of a midrange driver in a vehicle like the Ram 1500 contributes to even tonal distribution throughout the cabin by filling the frequency gap that may exist between bass sources mounted in the doors or dash and high-frequency tweeters.
