Hi,

If you have the M490 option (Speakers in Dash and Doors) vs the M441 Option (Dash speakers only - does anyone have this?), you have two amplifiers in the car.

The first is on the Radio Chassis itself which is 4 X 18 Watts. The second is the external Amp mounted under the Front Hood which is a (Swedish) HAES Verstarker - 4 X 40 Watts.

When adding the Rear Speakers on MY older than 2003, you are connecting to the Amplifier on the Radio Chassis. So your Dash and Door Speakers are powered by the external Amplifier and the Rear Speakers are powered by the Radio's own internal Amplifier. All connections for the Rear Speaker kit go to the Radio chassis.

On MY '03 and higher, you connect the Rear Speakers through the firewall and into the external Amplifier under the Hood. Source: Porsche TSB Group 9, #0301 9142 date: 8/22/03 Hope this helps...

Happy Motoring!... Jim'99
