Class D, 4-channel car amplifiers advancing


Dynamic product development and added features are keeping the line afloat.



  • Emphasis on class D amplifiers: R&D among many China suppliers revolves around class D car amplifiers, specifically 2 to 4-channel variants, under efforts to move upmarket. Many integrate value-added functions such as MP3 player, LCD screen and FM radio to raise sales.
  • Performance boost: Makers emphasize high efficiency, S/N ratio and power output, and low THD in latest releases. They turn to overseas partners STMicroelectronics, International Rectifier, National Semiconductor and Toshiba for quality MOSFETs and chipsets. To ensure stable operation, companies employ double-sided PCBs with FR-4 base material.
  • Price forecast: Quotes are expected to stay at current levels or increase by 5 to 10 percent in the months ahead. Rising material and labor costs, and the strengthening of the yuan are the main factors behind the potential markups.
  • Export projection: Overseas sales could slide by 5 percent because of economic hurdles in Europe and the US. Revenue from emerging markets such as South America and the Middle East will remain stable.
