Alpine Adventure Audio
The Alpine SPC-R100-DU is a vehicle-specific 12cm dashboard speaker upgrade for selected Fiat Ducato, Citroën Relay/Jumper, Peugeot Boxer and Vauxhall/Opel Movano vehicles. Its radial full-range design brings vocals and music closer to ear level for a clearer, wider and more enjoyable listening experience.
Product Overview
Factory door speakers are positioned low in the cabin and can be partially obstructed by the driver, passenger and interior trim. In larger motorhome and campervan cabins, this can make vocals, radio programmes, podcasts and navigation instructions sound distant or difficult to understand.
The Alpine SPC-R100-DU places two full-range speakers above the dashboard, bringing the sound closer to the occupants. This improves vocal clarity and creates a more natural front soundstage without requiring conventional speakers to be installed deep inside the dashboard.
Key Benefits
Alpine’s inverted-cone design distributes sound in every direction, creating a wide and balanced soundstage across the front of the cabin.
Bringing the speakers closer to ear level makes radio, podcasts, audiobooks, music and navigation instructions easier to hear.
With only 12mm of mounting depth and 45mm overall height, the speakers fit neatly above the dashboard without a large speaker or magnet cut-out.
Dedicated housings follow the shape of the dashboard and are designed to remain compatible with Remifront-style windscreen blind systems.
Designed for Larger Cabins
The SPC-R100-DU is particularly effective in vehicles with large cabins, where low-mounted factory speakers can struggle to deliver clear sound to the driver and passenger. It can be used with compatible original radios or aftermarket stereos and does not require an external amplifier for normal operation.

Yes. The SPC-R100-DU can be used with compatible original radios or aftermarket head units. Its 4-ohm impedance and 45-watt RMS power handling make it suitable for a high-quality speaker upgrade without requiring a separate amplifier.
A large speaker or magnet opening is not required. However, installation does require four small fixing holes to be drilled for each dashboard housing.
Expert Guidance
This speaker kit is ideal if speech and music from your existing system sound low or distant, particularly in a motorhome or campervan. The dashboard-mounted design improves front-cabin clarity without taking up storage space or requiring a large speaker opening. For stronger bass and greater overall output, the SPC-R100-DU can also form the first stage of a more complete Alpine Adventure Audio upgrade.
