Alpine Adventure Audio – Concert Ensemble upgrade
The SPC-W84AS907-2 upgrades an existing Alpine Adventure Audio speaker system in the Mercedes-Benz Sprinter 907 / 910 to the Concert Ensemble level. It adds power, dynamics and bass to the existing speaker system.
The DSP amplifier is pre-programmed to match the acoustic characteristics of the Sprinter 907 / 910 cabin. It can be further adjusted for steering wheel configuration (left or right hand drive), radio type and other factors. A wiring harness for the original Mercedes radio or aftermarket radios with RCA pre-amp outputs is included for straightforward plug-and-play installation.

Powerful Bass Upgrade
The 180W dual voice coil subwoofer comes pre-installed in a sealed wooden enclosure sized for installation under the Sprinter 907 / 910 passenger seat. It delivers strong bass without requiring additional enclosure work.
Fast & Easy Installation
All installation brackets and cable harnesses are included in the SPC-W84AS907-2 kit. The plug-and-play wiring harness connects to the original Sprinter radio or any aftermarket radio with RCA pre-amp outputs. No additional wiring is required.
