Important Audio-System Notice
This listing is for a Becker BE6600 DSP/MOST amplifier. Although some used-parts references loosely describe members of this amplifier family as Bose components, Porsche dealer information identifies the applicable service unit as a non-Bose/M490-style amplifier. Do not purchase solely because the vehicle has a premium factory audio system.
Before ordering, verify:
- The original amplifier number matches 99664533100 or a confirmed supersession.
- The vehicle uses the compatible MOST fiber-optic audio system.
- The original unit is a Becker BE6600.
- The connector sockets, mounting points, and housing match the photographs.
- The vehicle’s option codes and body-style configuration support this amplifier.
Installation Notice
Installation may require Porsche-compatible diagnostics to configure or recognize the replacement amplifier on the MOST network. A break or fault elsewhere in the fiber-optic loop can also cause loss of sound, so the existing system should be properly diagnosed before replacing the amplifier.
Package Includes
- One Porsche/Becker BE6600 DSP amplifier
No mounting bracket, wiring, fiber-optic cable, radio, speakers, installation hardware, or additional accessories are included unless visibly pictured.
