Case Study: Car Audio Head Unit Supply for a mining contractor in the Caribbean

Car Audio Head Unit for A mining contractor in the Caribbean

A mining contractor came to us with a car audio head unit programme for the Caribbean. 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

  • Premature wear on the first batch
  • Documentation that arrived after the container shipped
  • A specification nobody had written down

How it was resolved

  1. The specification was rebuilt around Tempered Glass 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.

Result

  • 5,000 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.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
