Infiniti I35 Rear Deck Lid Speaker Size
The Infiniti I35 rear deck lid accommodates an 8 inch speaker size across all listed model years. Compatible types for the audio system include woofer replacement units. These specifications cover the years 2002 to 2004.
| Year | Type | Size (inch) |
|---|---|---|
| 2004 | Woofer | 8 |
| 2003 | Woofer | 8 |
| 2002 | Woofer | 8 |
Speaker Types
| Type | Description |
|---|---|
| Woofer | A larger driver for low frequencies, typically from about 40 Hz up to 1,000 Hz. It delivers most of the bass and lower midrange in a door or panel speaker system. |
Additional Notes
- The rear deck lid location in the Infiniti I35 accommodates speakers mounted horizontally within the rear parcel shelf, a surface positioned between the passenger cabin and the trunk compartment.
- Deck lid installations typically involve a flush or near-flush mounting orientation, where the speaker cone faces upward toward the cabin ceiling or rear window glass, which affects sound reflection and dispersion patterns.
- An 8-inch speaker diameter occupies a relatively large mounting cutout, requiring adequate cone excursion clearance beneath the mounting surface to prevent mechanical contact during operation.
- The 8-inch cone area allows for greater air displacement compared to smaller diameters, which supports reproduction of lower midrange and upper bass frequencies in the 40 Hz to 500 Hz range.
- The Infiniti I35 rear deck lid position, combined with an 8-inch driver, places the sound source at the rear of the cabin, which influences the perceived stereo imaging and soundstage depth for front-seat occupants.
- A woofer is a driver designed specifically for low-frequency and upper-bass reproduction, functioning below the range handled by midrange drivers or tweeters.
- In the rear deck lid position of the Infiniti I35, a woofer's low-frequency output benefits from the acoustic loading effect of the trunk cavity beneath the deck, which can act as a passive enclosure influencing bass response.
- Woofers require greater cone excursion than full-range drivers to reproduce low frequencies accurately, making the depth clearance beneath the Infiniti I35 rear deck lid a mechanically relevant installation factor.
- The directional characteristics of a woofer are relatively omnidirectional at low frequencies, meaning the upward-firing orientation common to rear deck lid installations does not significantly compromise low-frequency dispersion throughout the cabin.
- The 8-inch woofer designation across the 2002, 2003, and 2004 model years indicates a consistent mounting cutout dimension and depth clearance requirement for all 3 years of the I35's production run.
