Case Study: Car Speaker Supply for a motorcycle assembler in Europe

Car Speaker for A motorcycle assembler in Europe

A motorcycle assembler came to us with a car speaker programme for Europe. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • A supplier who changed material without saying so
  • A fitment that looked right on paper and failed on the bench
  • Lead time that slipped twice before bulk started

ClientA motorcycle assembler
MarketEurope
Volume20,000 pieces across 3 specifications
Base materialForged Aluminium
Sampling rounds3
Delivery window10 weeks from PO to ex-factory
ComplianceECE R90

How it was resolved

  1. The specification was rebuilt around Forged Aluminium and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Car Speaker production run

Result

  • 20,000 pieces delivered inside the 10-week window.
  • Unit cost held within 4.5% of the original quotation.
  • Inspection-related rejection stayed under 1.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
