Car Audio System Specification Example for Scooter Fleets: Drilled and Slotted
Car Audio System Specification Example for Scooter Fleets: Drilled and Slotted
This is a worked specification for car audio system in a drilled and slotted programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The drilled and slotted version exists because the duty cycle on scooter fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.
Example specification
| Item | Car Audio System |
|---|---|
| Application | Scooter Fleets |
| Version | Drilled and Slotted |
| Base material | PVC Coated Fabric |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.05 mm |
| Finish | zinc plated |
| MOQ | 200 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | REACH |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — PVC Coated Fabric, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- CNC machining
- ultrasonic cleaning
- electroplating
- rubber vulcanisation
- shot blasting
- laser cutting
Where this example applies
Programmes that run drilled and slotted most often specify this build for scooter fleets. Related applications include passenger cars, three-wheelers, delivery vans, workshop replacements, city buses.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the REACH-compliant build instead of a fresh interpretation.
What testing is included?
Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
