The GMC Yukon overhead location accommodates a 4x6 inch speaker size, supporting 4x6 inch units in the overhead position. Full-range speakers are the compatible type for the audio system in this configuration. These specifications cover the 1996 to 1997 model years.
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 overhead location in the GMC Yukon positions speakers in the headliner, a surface that is fixed, shallow in depth, and oriented to project sound downward toward rear passengers.
Headliner cavities are typically shallow, which limits the available mounting depth and restricts compatibility to drivers with compact basket profiles.
The 4x6 inch oval format accommodates the elongated, space-constrained cutouts common in overhead headliner panels, where a circular speaker of equivalent cone area would not fit within the same footprint.
A 4x6 inch speaker, due to its relatively small cone area, reproduces a frequency range that extends from the upper bass region through the high frequencies, with diminished output in deep bass compared to larger formats.
The overhead placement of a 4x6 inch driver means sound travels directly downward at short range to seated passengers, which supports intelligibility in the midrange and high-frequency bands that dominate vocal and ambient content.
Full-range drivers are single-unit speakers designed to reproduce the entire audible spectrum without relying on a crossover network or supplementary tweeters, making them suited to installations where only 1 speaker position is available per channel.
In an overhead location, a full-range driver handles low, mid, and high frequencies simultaneously, which is acoustically relevant because no additional speaker positions in the headliner are specified to share the workload.
The GMC Yukon overhead position with a 4x6 inch full-range driver covers model years 1996 and 1997, establishing the dimensional and type parameters for that specific installation across both years.
