I'm from italy and I have a Mercedes C-Class 220 (year 2003) Avantgarde.
When I bought the car I got the original CD-STEREO with 10 BOSE speakers.
I am very satisfied of the speakers, but the original CD-STEREO is very very
So I want to change it with a CLARION/PIONEER mp3 stereo.
Somebody told me that I need particular adapter to install a new stereo in
Is that true? What I need to install a new stereo? Can I buy this online?
My last question is: is there a cd-stereo (mp3) that is able to keep the
steering stereo controls?
Sorry for my bad english :P I tried to do my best.
I Hope someone will answer to my question.
(keep out NOSPAM)
Oops, my Italian spelling is hopeless. I knew there was something wrong but
could not see it. And last month I spent 5 days in Magnificent Milano
(mostly family holiday).
For direct contact replace nospam with schmetterling

I do not know the answer to your question about a new stereo head
unit. However, you should know that the Bose speakers have a 2-3ohm
impedance which many amps cannot handle. Just make sure that whatever
you pick can run these speakers.

Hi, thanks for your message.
What do you mean with:
amps cannot handle.
Even if I have an HARDSTONE amplifier I did not programmed to use it, but I
want to use the internal amplifier
of the stereo that I' am going to buy....
Mmmh... If I want to know the exact value of impedence/ watt of the speakers
installed in my car how can I do?
Do you think that if I look at their backside I would find this values?
Speakers which measure 2 to 3 ohm on a mulitmeter are 2 to 3 ohm resistance.
They are probably 4 ohm impedance.
It is all due to "inductance" which you cannot measure on a simple
While what you say is true, there are several reports that the Bose
speakers actually have an impedance of 2-3ohms, not a DC resistance.
That makes them marginally compatible with non-Bose head units.
There are several MB newsgroups where this has been discussed.
Possibly but, since this has been discussed on the newsgroups, you
should research it before deciding. I am afraid that I cannot recall
where this was discussed, it was at one or more of these:
I suggest a little search at those sites.
Most likely, the audio system is using an amplifier, or knowing Bose, a
couple. Bose is very particular with their systems, they always seem
to have external amplifiers to handle the lower impedence of their
speakers, not to mention the equalization needed to enrich their sound.
I doubt that your stero will be running the speakers, it will be the
amplifier. The question is, will you be able to hook into it? If it
is using Speaker level inputs, great, just figure out the colors. If
it is RCA/line level, then you will need to make sure you get a head
unit with both front and rear RCA outputs, otherwise you will lose
