Removing of tweeter grille & radio module outputs

[pvoltti]

Hello

I bought my X5 a week ago. I do have a non-DSP system with navigation. Anyway, the whole set-up looks quite exotic.

Now I have two items where I need some help:
1. Replacing new tweeters: what is the best way to do this? Do I just remove the tweeter grille or do I have to do something else.

2. Radio module. As far as I have understood the system set-up, all the audio signals are routed via the radio module. Can anybody help me with the radio module output connector. I want to bypass the original amplifier with a "real amplifier". There's four pins for front speakers in the radio module. Are those outputs line-level outputs or speaker level outputs?

thanks
