Product Information

Alpine Adventure Audio - Sound Experience

 The subwoofer is integrated perfectly in the center console for a stealthy appearance.

Overcoming Limitations

The SWC-D84S is designed to overcome the audio limitations of the Fiat Ducato cabin. The vehicle’s 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. By adding this subwoofer to the center console, you can enjoy much deeper and cleaner bass and overcome the mentioned issues from the ground up.

20 cm Shallow Subwoofer

The 20 cm shallow-type, dual-voice coil (2 Ohm + 2 Ohm) subwoofer features 250 Watts peak power handling and can be connected to the 2 rear channels of your original or aftermarket radio. If you have rear speakers connected to your radio, you can continue using them in parallel to the subwoofer. We recommend to use the SWA-150KIT Power Amplifier Kit for an even stronger bass output and dynamic.

Perfect Installation

The included steel installation bracket gets mounted to the center console structure below the original cup-holder. The subwoofer enclosure then slides in from the front and perfectly blends into the center console. A cable harness for simple plug-and-play connection to the radio is included. Note that the original cup-holder is mandatory for this installation and needs to be installed as well, if not originally available.

Vehicle Compatibility

We designed the SWC-D84S to be compatible with Fiat Ducato 3, Citroën Jumper 2 and Peugeot Boxer 2 motorhomes and vans. Mandatory condition is the original cup-holder* in the center console. The cup-holder can be purchased separately from the vehicle manufacturer.

Included Plug-And-Play Wiring Kit

The SWC-D84S includes an ISO cable kit for head unit adaptation. It connects the two rear channels to drive the subwoofer. There is also a low-pass filter that gets connected in line to limit the bandwidth frequency for the subwoofer.
