The Audi RS5 rear deck lid accommodates a 3 inch speaker size and 10 inch speakers, with each location supporting its respective size. Compatible speaker types across these positions include full-range units and subwoofers. The specifications cover the 2013 to 2018 model years.
A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers.
Full-Range
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 of the Audi RS5 is a horizontal panel positioned at the top of the trunk, behind the rear seat and beneath the rear window, placing speakers in a location that fires upward into the cabin.
Mounting in a deck lid surface typically involves shallow to moderate depth clearance, as the panel must accommodate the trunk structure beneath it, which constrains the physical depth of any installed driver.
A 3-inch driver occupies a small mounting cutout diameter, making minimal demands on the deck lid's available surface area and requiring relatively shallow mounting depth.
At 3 inches, a full-range driver in the Audi RS5 rear deck lid handles the upper portion of the audible spectrum, primarily mid and high frequencies, contributing to treble clarity and vocal presence from the rear of the cabin.
Full-range drivers are designed to reproduce multiple frequency bands within a single cone and voice coil assembly, without the need for a passive crossover network to separate frequency bands before the driver.
The positioning of a 3-inch full-range unit on the deck lid places high-frequency content at the rear of the vehicle, where the upward-firing angle can reflect sound off the rear window toward the front of the cabin.
A 10-inch driver requires a significantly larger mounting cutout than a 3-inch unit, demanding more surface area on the deck lid and greater structural accommodation within the panel.
The Audi RS5 rear deck lid 10-inch subwoofer compatibility indicates the location has sufficient physical dimensions to support a large-diameter low-frequency driver at this installation point.
Subwoofers are dedicated low-frequency drivers, typically reproducing bass content below approximately 80 to 120 Hz, where wavelengths are long and directional localization by the human ear is limited.
A 10-inch cone surface area moves a substantial volume of air relative to smaller drivers, which is associated with the generation of deeper and louder low-frequency output within an enclosure or mounting panel cavity.
The deck lid cavity beneath the mounting surface can act as an acoustic enclosure for a subwoofer, with the available internal volume of that cavity influencing the low-frequency response characteristics of the installed driver.
The simultaneous specification of 3-inch full-range and 10-inch subwoofer positions in the RS5 rear deck lid indicates the location accommodates 2 distinct driver sizes serving separate, non-overlapping frequency roles within the same mounting zone.
