Alpine Adventure Audio sound experience
Alpine Adventure Audio systems are designed for the specific acoustic demands of motorhomes and camper vans. Alpine offers a three-stage sound system upgrade for the Fiat Ducato 3 and vehicles on the same platform.
The SPC-R100-DU creates a clear front sound stage in the cabin and significantly improves overall sound quality. Vocals are noticeably cleaner — particularly useful when listening to news, podcasts or audiobooks.
Overcoming limitations
In the standard Ducato system, the tweeter and woofer are placed far apart, producing unbalanced sound. Vocals are handled by the door speakers, which sit behind the driver's and passenger's legs. The Ducato doors also lack internal soundproofing, causing vibration noise from the inner panel and letting audio bleed out to neighbouring pitches on a campsite.
The SPC-R100-DU addresses these issues by adding full-range speakers on top of the dashboard, replacing the original tweeters entirely.
On-dash radial speakers
The 12cm inverted-cone design provides 360-degree sound radiation from the top of the dashboard. Detail is excellent across vocals and music, and the raised position removes the acoustic interference caused by the original door speaker placement.
Easy installation
Included speaker brackets are shaped to the Ducato dash and fix with screws. The inverted cone keeps the profile very flat — no cutting required for the speaker basket or magnet. Cable adapters are also included for plug-and-play connection to the original tweeter wiring harness.
Vehicle compatibility
The SPC-R100-DU is compatible with Fiat Ducato 3, Citroën Jumper 2 and Peugeot Boxer 2 motorhomes and vans. When fitted, the speakers do not interfere with the Remifront or other windscreen blinds.

About the Alpine SPC-R100-DU
From our tech experts at CEN
Vehicle-specific speakers designed for the Fiat Ducato, so they fit the factory locations using the existing mounting points and connectors rather than needing adapter rings cut to fit.
Who it suits
Fiat Ducato owners who want a real improvement over the factory speakers with no cutting or fabrication. Plug-and-play sets like this are the usual starting point, because the work is contained and the result is immediate.
Our tech experts advise
They will play louder and cleaner with an amplifier behind them, and doors usually benefit from sound deadening before you hear what the speakers can really do. Model years and trim levels vary, so get in touch to confirm this set suits your exact vehicle. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Which vans do the Alpine SPC-R100-DU speakers fit?
A: Fiat Ducato III (250 from 06/2006, 250 facelift 2011 to 2014, and 290 from 2014), Citroën Jumper II (250) and Peugeot Boxer II (250) from 06/2006. Liner motorhome owners should check compatibility before buying.
Q: Do I need to cut the dashboard to fit the SPC-R100-DU?
A: No. The flat inverted cone design means no hole is needed for the basket or magnet. The brackets screw onto the dash and cable adapters plug into the original tweeter harness.
Q: Will the SPC-R100-DU work with my original radio?
A: Yes. They are compatible with the original radio and with aftermarket head units, and do not interfere with Remifront or other windscreen blinds.
