ARTICLE: Plug-and-Play Van Speaker Upgrades for Sprinter, Transit & ProMaster
Last updated: November 3, 2026
GoCode offers plug-and-play front speaker upgrades for Mercedes Sprinter, Ford Transit, and Ram ProMaster vans. Each kit drops into the factory speaker locations with vehicle-specific connectors, so no cutting, rewiring, or amp is required. Sprinter gets a three-piece ETON system with a center channel. Transit gets EMPHASER and ProMaster gets ETON, both front door and tweeter systems.
What Does a Van Speaker Upgrade Replace?
Each kit replaces the factory front door speakers and the tweeters up by the A-pillars with upgraded components. The Sprinter kit also replaces the factory dash center speaker. Everything mounts in the factory speaker locations, so the van keeps its original radio and wiring.
Which Speaker Upgrade Fits My Van?
Each kit is built for one platform, so pick by van.
Van | Kit | Fits | System |
|---|---|---|---|
Mercedes Sprinter | ETON | VS30 (907/910), June 2018 and newer | 3-piece with center channel |
Ford Transit | EMPHASER | Transit and Transit Custom (7th gen) | 2-way |
Ram ProMaster | ETON | 2014 and newer. Also fits Fiat Ducato III, Peugeot Boxer II, Citroen Jumper II, and Opel Movano | 2-piece |
How Easy Is Installation?
All three kits are plug-and-play. Vehicle-specific connectors plug into the factory wiring, so there is no splicing, cutting, or amp to add. Estimated install times from the GoCode install guides:
Sprinter: about 1 to 2 hours
Transit: about 30 minutes to 1 hour
ProMaster: about 30 minutes to 1 hour
The work is the same on every van. Remove the door panel or speaker cover, swap the door speaker, then pull the A-pillar trim to swap the tweeter. Each install guide lists the exact tools and steps for that van.
How Do the Specs Compare?
Kit | Woofer | Tweeter | Center | Power handling | Impedance | Sensitivity |
|---|---|---|---|---|---|---|
Sprinter ETON | 165mm (6.5") coated paper cone | 25mm coated fabric | 80mm (3") | 50W RMS / 80W music | 3 Ohm | 89.5 dB |
Transit EMPHASER | 165mm (6.5") aluminum cone | 25mm fabric dome | Not in kit | 50W RMS | 4 Ohm | 90 dB |
ProMaster ETON | 165mm (6.5") paper-fiberglass cone | 25mm coated fabric | Not in kit | 60W RMS / 90W music | 3 Ohm | 91.5 dB |
The EMPHASER kit also lists a 12 dB/oct crossover at 3,200 Hz and a frequency response of 50 Hz to 22 kHz. The ProMaster kit includes a cable crossover with level adjustment.
Do These Kits Need an Amp?
No. All three product pages say no amp is required, and each kit is built to run directly from the factory radio. They replace the factory speakers and work the same way.
Why Does the Sprinter Kit Include a Center Speaker?
The Sprinter has a factory center speaker in the dash. The ETON center channel fits the factory 65mm opening and uses a dual-terminal connection that carries both the music signal and the factory emergency call assistant signal. That keeps the Sprinter's factory safety feature working alongside the upgraded audio.
Should I Add Sound Deadening?
It's optional. With the door panel already off, the Transit guide suggests adding sound-dampening material in the door cavity, kept clear of the window track. The ProMaster guide suggests a sound deadening mat on the door sheet metal behind the speaker, which it says gives tighter bass and less rattling.
