Question: is the CDR210 screen supposed to be backlit? Mine is invisible at night - meaning, not backlit.

And another question regarding the Kienzle 1016: the head unit has a 4x40w (max) output. Is this sufficient for avg aftermarket speakers? Can this be configured to power all six speakers: the 2 tweeters, 2 door speakers, and 2 rear deck speakers (non-HiFi setup)?

I'm not going for a killer stereo upgrade, just want to hear things a bit more clearly than now.

Yes, it is upposed to be backlit.

I eliminated my Nokia amp, and the Kienzle is way louder than the old setup with the CDR210, and much clearer. Things have definitely improved since the technology of 1995. I just wired the tweeters and drivers in parallel for the fronts since I was too lazy to install crossovers, and it sounds fine with the stock speakers. If I upgraded to a modern 2 way in the front I bet it would even better.

Mine is running with the stock Nokia amp and sounds great. I had an aftermarket Kenwood deck in there before wired to the Nokia amp and it literally sounds the same. Very clear and I'm somewhat picky about acoustic sound.

I've heard this deck without the amp, and yes it's far better than the factory 210 with hifi. However in comparison to mine it's a bit flat.

Everyone's level of tolerance is different, if your somewhat picky I would buy an aftermarket amp and run it with Kienze. Guaranteed it will be far superior!

Thanks deekay and knight!!

A radio's power output stage in RMS terms is what to look for.
Automotive 12v radio's,, say,, 1 DIN chassis units types such as the Kienzle, Continental, Pioneer, Alpine, others, etc. all utilize an IC chip output stage.
In RMS per channel terms these radio's are rated in the range of 14w to 18w RMS per channel. Any higher # is nonsense, marketing speak. Audio fidelity or Hi Fidelity character of the output amplifier stage is a function of its IC chip. Popular 12v market IC chip's are from NEC, Toshiba, Phillips . . . a pretty generic lot.

+993 ...
The pallet of 12 Volt automotive audio components has changed substantially since the early 90's, about the time PAG commissioned Nokia for the 993's audio offerings, the passenger seat located external amplifier is a good example.
The external amplifier (Nokia) is based on a inexpensive, sonically mediocre Phillips IC chip, TDA1552Q, a class B amp (BTL) used throughout the automotive 12V market in the '80's & '90's.

The 993's HiFi speaker option does have some merits sonically other than the crummy '90's audio amplifier; its an active speaker arrangement, partially. A design (active) ahead of its time for the early '90's. Improving the active speaker system is easy.

As example: Total Harmonic Distortion of the 993's Nokia amplifier.
At 12watts @ch THD = 0.5%
At 17watts @ch THD =10.0% 10% distortion is huge, acoustically unbearable.

The 2nd tier Digital HiFi option's amplifier, additionally utilizes a Cirrus Logic IC (CS4225) for the stereo 16 bit D/A conversion. A fancy tone control fader arrangement in the drivers arm rest.

DeeKay911 and Knight,

Does the Kienzle unit have line-outs in Socket C1 or did you have to use a Line Out Converter (LOC) to retain the Nokia HiFi amplifier, please?

Thanks!

This is appliable to CDR22/220:
It happens that the Socket A/Pin 6 is not powered, then no illumination. Check if your corresponding A6 of the connector (coming from the car) is wired and delivers 12V when your lights are on.

deekay911

The Kienzle manual mentions line-outs, but there is no indication where they are in the top sockets (C1, 2 and 3), Its not C1 though...I thought about a LOC but that's just more hassle to use a low tech amp.

The only reason for me to keep the Nokia would be for originality, and maybe save a little time on the install, but it doesn't add anything acoustically as far as I can see (see THD figures above...).

Knight

A shop installed mine and they used a LOC as this deck has no RCAs.

GT917

BTW, my CDR 21 has the same pin A6 to be powered in order to get screen illumination. So, you should check I believe.

I travel to Europe frequently and bought my Kienzle unit back form Germany with me. I bought a second one in case anyone else was interested. I will pass that one on at cost (109 EUR = 120 USD) if anyone is interested.

Bluetooth, USB, SD card, cool retro look for $120...
