What size speakers are in a Ford Transit Custom?
Front-door woofers are typically 165 mm (6.5 inches) with a separate tweeter; cargo-focused variants usually do not come with rear speakers by default.
Speaker sizes by location
The following outlines typical sizes and components found in most Transit Custom configurations.
Front-door and dash components
- Front doors: 165 mm (6.5 in) woofers, standard in most European-spec Transit Custom models.
- Tweeters: small 25–28 mm (about 1 inch) dome tweeters mounted in the dash corners or A-pillars.
- Rear area: cargo versions generally do not include rear speakers; where present in passenger/crew variants, sizes vary by year, market, and trim.
In practice, the primary up-front system is built around a 6.5-inch woofer with a 1-inch tweeter, while rear speakers are not a given on most cargo-focused configurations.
Generational and market differences
Ford has offered the Transit Custom across multiple generations with regional variations. In Europe, the standard front-stage configuration has largely remained centered on 165 mm front woofers and 1-inch tweeters, though some trims or optional audio packs may alter mounting depths or introduce different dash speaker arrangements. In markets outside Europe, or in different model lines such as the larger Transit, configurations can differ, so always verify against your specific VIN/build sheet or service manual.
Upgrade considerations
If you’re upgrading the sound system, keep these practical points in mind to ensure a clean fit and proper operation.
- Fitment and mounting depth: Most 165 mm (6.5 in) aftermarket woofers fit the front doors, but check the available depth (often around 60–70 mm) to avoid clearance issues behind the panels.
- Impedance and wiring: Confirm the factory speaker impedance and use appropriate adapters if needed; many aftermarket sets use 4–8 ohms and may require wiring harness adapters to preserve factory connections.
- Brackets and harnesses: You’ll likely need mounting brackets and wiring adapters to align with Ford’s connectors and to avoid modifying the door panels.
Once you account for mounting depth, impedance, and adapters, upgrading the front stage is typically straightforward, while rear speaker upgrades depend on whether your exact variant includes rear speakers.
What to measure and how to confirm
To verify the exact sizes for your van, perform these checks:
- Inspect the door panels to read any size stamp or model number, or temporarily remove the grille to measure the woofer diameter and mounting hole pattern.
- Check the dash or A-pillar area for the tweeter and measure its diameter if needed (common is around 1 inch/25–28 mm).
- Consult your vehicle’s build sheet or VIN-specific documentation—Ford dealers can pull the official audio specs for your exact trim and market.
- Cross-check with reputable online resources or service manuals for your year and region to confirm standard sizes before ordering replacements.
Accurate measurements and official specs help ensure compatibility and save time when ordering replacement speakers or upgrade kits.
Summary
For most Ford Transit Custom models, the standard front-door setup uses 165 mm (6.5 in) woofers paired with a 1-inch tweeter, while rear speakers are not standard on cargo-focused variants and may vary on other configurations. Because sizes can shift with year, market, and trim, always verify using the vehicle’s VIN/build sheet or a service manual before purchasing replacements or upgrades. A careful check ensures you choose components that fit properly and maintain proper electrical compatibility.
