DS Automobiles car audio and speaker upgrades in 2026

DS Automobiles positions itself as the premium arm of the Stellantis group, and the cabins live up to it with soft leather, quilted seats and thick sound insulation. The factory speakers do not match that standard. Paper cone drivers with small magnets leave the sound thin and lifeless, especially in the DS 7 Crossback where the cabin volume is large. A direct-fit Focal speaker upgrade brings the audio up to the level of the interior in around an hour of fitting time, with no visible changes to the car.

Popular DS models we stock for

DS 3 and DS 3 Convertible. The original Citroen-badged hatch and cabrio from 2012 to 2017, with the same door apertures as the C3 of the period.
DS 3 Crossback. The compact SUV from 2019 to 2025, including the electric E-Tense models where quiet running exposes weak factory speakers.
DS 4 and DS 4 Crossback. Hatch and raised Crossback from 2011 to 2018.
DS 7 Crossback. The flagship SUV from 2018 to 2022, a large cabin that benefits most from component speakers.

Brand quality at a glance

Focal. French engineered speakers built specifically for PSA door locations and connectors, so fitting is plug and play in every DS listed here.
Pioneer. The leading choice for Apple CarPlay and Android Auto head units in older DS 3 and DS 4 models with a standard dash aperture.
Kenwood and Alpine. Premium screen units with wireless CarPlay, DAB and high resolution playback for owners who want a step up.
Connects2 and Autoleads. Fascia adapters, harnesses and CAN Bus interfaces that keep steering controls, parking sensors and displays working.

Coaxial or component: which Focal kit to choose

The 280 watt coaxial kits put the tweeter in the centre of the woofer, so one speaker replaces the factory door unit and the job is done. They deliver a clear improvement in detail and bass with the least work. The 240 watt component kits separate the tweeter and mount it in the factory dash or pillar position, which raises the soundstage to ear level and gives a wider, more precise stereo image. In a DS 7 Crossback or DS 4 the component set is the choice we recommend, and it pairs well with a compact amplifier later.

Compatibility and fitting

Speaker kits fit without adapters. If you are replacing the head unit in a pre-touchscreen DS you will need:

Fascia adapter. Reshapes the DS dash aperture to take a double DIN stereo with a factory finish.
ISO harness. Plugs into the original PSA connector so no factory wiring is cut.
Steering wheel control adapter. CAN Bus interface that retains volume, track and phone buttons and keeps parking sensor and trip computer displays live.
Aerial adapter. Converts the FAKRA aerial connector to DIN, with phantom power for the amplified aerial.

DS shares platforms with Citroen, so the wider Citroen car audio upgrades range covers stereos, cameras and fitting parts for most DS models.

Adding bass to a DS

The DS 3 boot is small, so a slimline underseat or spare wheel well subwoofer is the sensible route and keeps luggage space intact. The DS 7 Crossback and DS 4 have room for a compact sealed enclosure and a four channel amplifier that also powers the new Focal door speakers. Every bass package includes the wiring kit, and a line output converter lets you keep the factory touchscreen.

Common DS fitting issues we solve

Most DS 3 Crossback and DS 7 Crossback models integrate the screen with climate and vehicle settings, so full stereo replacement is not practical. In these cars a speaker upgrade plus a small amplifier is the right approach and it keeps the interior untouched. Owners of earlier DS 3 and DS 4 models sometimes lose steering wheel button function after a stereo swap, which is solved by a CAN Bus interface with the correct PSA vehicle profile. Rattles from door cards after fitting are cured with the sound deadening pads we supply.
