low-level output on stock system

[masons]

I will be upgrading the front end and adding a sub but will only be using the front end signal for both.( using onboard x-overs) .
The car is a 2001 4.4 sport with sat nav but no dsp or sub, so i gather no amp.
I didn't want to start a new tread as most of the information is here and i do think it may answer some other peoples questions.

You may have an amp, so you will have to explore the boot to check it out. There were two versions of the non-DSP audio system. The "HiFi" system had a basic 10 channel amp. The standard stereo system was powered directly from the radio module. If you are just adding a sub, then it may not matter-- just tap an audio signal coming out of the radio module, and you should be set.

If you want to add an amp for the main speakers, then you will have to confirm whether or not you have a HiFi amp to remove first. It is located in the compartment with the CD changer and nav computer.

I do not have an amp in that panel at guess it would be below the cd changer.

That is where the amp would be, so you have the standard stereo audio system.

So my other post regarding pin numbers would be correct.

I will be starting a tread for other questions.
Thank you very much for your help.
