Rear Speakers And 940 Ampifier

Recommended Posts

I would like to connect my rear speakers on my 940 amplifier.

However according to my Porsche dealer there is no output signal on my amplifier.

After receiving a wire diagram from Loren I noticed the same problem.

I think that there are two possibilities for this problem:

1. on the 940 boxster amplifier there is no standard possibility for adding rear speakers. Sounds strange to me.

2. my amplifier is mal functioning I need need to buy a new one? Sounds strange to me?

Who could give me the right answer??

I am not the stereo guy, and do not know what a 940 amp is. The standard amp on your 2002 is 4 channel. I think you need a 6 channel amp, like from a 996 or aftermarket, if you want to power the rear speakers and be able to have a fader function. Otherwise you have to connect them to the radio head.

The amp on the 2003/4 MOST cars is 6 channels and the rear speakers are hooked up to the amp.

In the US Porsche sells a rear speaker kit. On your year the rear speakers are powered from the radio head. In the picture you see a brown plug - that is for the rear speakers.

In the second picture the owner did not have the brown plug so the wires for the rear speaker were hooked up using electrical terminals.
