do I have Bose system?

[valcax]

I have boxster 986 MY99 but I am not sure audio system is bose. It has six speakers (two on dashboard, two on door panel, and in rear part seats), but no subwoofer. Where subwoofer should be, there is a glove box,

option code 490 and 680 is included

No BOSE did not arrive in Porsche until MY2002.

You have an amp and digital sound package. You should have a DSP in the console for that system.

I guess the 490 is hifi system and 680 dsp (digital sound package) but without bose ....¿?

My doubt comes from option code 680 is the same as bose option code.

[Richard Hamilton]

Loren is absolutely correct. M680 option code was used for the DSP module up to MY2001, and from then on for Bose. MY2002 M680 Bose was an analog system, and from MY2003 was the MOST digital system.

M490 was the Harman (Haes) amplified sound package.
