Alpine Adventure Audio sound systems are designed to deliver excellent sound quality and match the needs of motorhomes and camping vans.

These systems feature new, innovative audio-technologies to achieve the best sound quality in your motorhome. Alpine offers a sound system upgrade in 3 stages for the Fiat Ducato 3 and the same platform of vehicles.

The SPC-R100-DU 12 cm Radial On-dash Speakers create an excellent sound stage in the cabin and strongly improve the vehicle’s sound quality. Especially vocals appear much clearer when listening to news or podcasts. They are compatible with Fiat Ducato 3, Citroën Jumper 2 and Peugeot Boxer 2.

The Companion Ensemble

Alpine Adventure Audio - Sound Experience

We highly recommend to upgrade your Fiat Ducato to the Concert Ensemble (consisting of SPC-R100-DU 12 cm Radial Speaker System, SWC-D84S Subwoofer System and SWA-150KIT Power Amplifier Kit) for the best sound experience in your motorhome.

Overcoming Limitations

On-Dash Radial Speakers

Overcoming Limitations

The SPC-R100-DU is designed to overcome the audio limitations of the Fiat Ducato cabin. In the original system, the tweeter and woofer are placed far away from each other, resulting in an unbalanced audio appearance. Vocals are reproduced by the door speakers, which are covered by the legs of the driver and passenger. The Ducato doors have no internal sound-proofing, resulting in strong vibration noise of the inner door panel. Audio playback is also heard easily by neighboring motorhomes on a camping site, due to the missing sound-proofing. The basic concept of the SPC-R100-DU is adding full-range speakers on top of the dashboard, to overcome the mentioned issues from the ground up.

On-Dash Radial Speakers

The 12 cm radial full-range speakers are installed on top of the dashboard and replace the original Ducato tweeters. These speakers feature an inverted cone design, resulting in an excellent 360-degree sound radiation. They deliver excellent sound detail, especially for vocals. This really improves listening to news, podcasts or audiobooks, but also regular music tracks will sound more detailed and balanced.

Easy Installation

Vehicle Compatibility

Easy Installation

Installing the SPC-R100-DU speakers on your dashboard is very easy. The included speaker brackets fit perfectly to the shape of the dash and get mounted with screws. Due to the very unique speaker design with an inverted cone, we could design the overall speaker very flat, therefore eliminating the need to cut any hole in the dash for the speaker basket or magnet. There are also cable adapters included, allowing a simple plug-and-play adaptation to the original tweeter cable harness.

Vehicle Compatibility

We designed the SPC-R100-DU to be compatible with Fiat Ducato 3, Citroën Jumper 2 and Peugeot Boxer 2 motorhomes and vans. When installed, the speakers will not interfere with the function of the “Remifront” or other windshield blinds.

Upgrade to Crescendo Ensemble

Upgrade to Concert Ensemble

Stage 2: Upgrade to Crescendo Ensemble SPC-R100-DU and SWC-D84S

You can upgrade your Ducato Sound experience to the second stage, the Crescendo Ensemble. The SWC-D84S subwoofer system integrates perfectly in your Ducato’s center console below the cup holders and drastically improves the bass of your system. This subwoofer system has very low power requirements and can be driven by the rear channels of your head unit.

Stage 3: Upgrade to Concert Ensemble SPC-R100-DU, SWC-D84S and SWA-150KIT

The final upgrade stage (SWA-150KIT) to your Ducato Adventure Sound system adds a power amplifier to drive the SWC-D84S subwoofer. The result is a huge improvement of dynamic and bass power. This 150 Watts digital amp is very compact and can be easily installed behind the glove box of your Ducato. The kit comes with a wired bass remote knob that gets installed in the dashboard for easy access to bass gain, as well as full wiring harness for plug-and-play connectivity to your radio.
