There has been a few threads about how the factory cd player wont play burned cds. It will play store bought cds although not very well. My brand new nakamichi wont play burned cds either. i have done some research and found that store cd's are recorded as cda files and burned cd's are wav files. AH HA solution!!! visit cnet and download a burner that burns mp3s as cda files and presto!!! still wont work. I thought it was a speed issue but even at the slowest speed, no dice. So whats the deal? What else is different on a store bought cd vs a burned cd? encription rate? tag line? This directly relates to not wanting to hack up my bose dash. I know we can figure this out!!

Something I found while searching the web about nakamichi:

[QUOTE]I don't recommend this unit if you have a lot of burned CDs, especially the TDK brand. Verbatim works a lot better in my unit.[QUOTE]

my 89 verts factory stereo plays the burnt cds better than itplays the storebought cds...burnt cds skip less than storebought..it could be how you burn them..mp3 will never play off of a cd in a regular cd player. but if you use easy cd creator (thats what ive always used) it will convert your mp3 files into readable wav files for you and then create a table of contents so your stereo can read it..thats just how ive been doing it and it always works for my old *** problematic 1989pioneer stock cd player(which ive actually had no problems with but everyone else seems to)

Hi Keynote22,

the problem is not the file format. MP3s should always be converted into "real" CD-A files because the FD stock CD player has no Decoder built-in. Of course not, it's from 1992! ;-)
Older CD-Players have problems reading burnt CDs because of the different (worse) reflection characteristics. Maybe another CD-R brand oder even a CD-RW (my Sony home DVD-Player has the same problems with CD-Rs and most CD-RW work!) will work. That'S try and error.
In Germany there was no 1-CD-player available. You could buy a 6-CD-changer with a control unit. This had a front-line-in. Wow! So you could plug in a aftermarket Disc man with MP3 capabilities or other MP3 car add-on things.
There's the possibility to make your own aux-in, but for that some wiring know how is needed. The round 13-pin connector has line-ins. If you are interested in that, let me know, maybe I can help a bit.

Kind regards
Tobias

keynote22

thanks tobias, that would explain why I have 1 burnt cd that works in my car. I thought it was because I burned it with a really old burner and the coding was different. I'll have to stop using cheap cd-rs and pick up some more TDK's. It always sounded like it was skipping when it was actually having a tough time reading. Let me give it a shot and see what happens.

Different brands of blank media might play in your stereo. Try some brands but mostly try the blank music cds.
Sony and a probably a few others by now have a 10disk changer that adds on to any factory radio and it plays MP3s, they even sell a slighty more compact 6 disk version as well. I have one in my Lexus, works great and I didnt have to change the factory set-up.

Sorry to rain on the parade everyone, but my 94 stock Bose system plays my burned CDs just fine. The burner I use is a cheap Multiread type CD-RW capable of 16x (but less than 2 years old).

I burn my CDs direct (using Adaptec DirectCD) or from MP3s through a ripper/decoder by Canon called E-Jay at about 4x. The conversion is to .wav files. For media I have used everything from cheapo (Staples store brand, K-Hypermedia, Kensiko) to TDK and Nashua. The only thing that does not work is any brand CD-RW even burned as a CD (closing the session).

Wish I could help clear this up but thats just how it is here.

RX-7-Tobi

Hi folks,

maybe Mazda changed the cd-drive unit in it's radio by the time. Who knows? ;-)
Keynote, what year was your FD produced?
You could try to burn the CDs with your old and slow burner. Maybe he burns better because that time a lot of drives where much more sensible to burned CDs becuase it was not usual.

keynote22

she's an oldie, 93. I need to get to germany one of these days...need some new leiderhosen. lots of great info on your sight. butken meinin deutchin ist terriblin



hefe weizen ein grosses!!

RX-7-Tobi

You mean Lederhosen.
One of those stereotypes. ;-) When Americans think of Germany they have Bavaria in mind (where I live ;->).
You won't believe me, but even in Bavaria people hardly wear these traditional things. ;-)
The RX-7 FD Audio site at the moment is not that interesting for non German FD owners at that moment.
The German sound system was different to all of the others. On my site I explain how easily improve the sound reproduction of the stock system without the need to install aftermarket speakers or amplifiers. In Germany the FD is a very rare car, I would say a collectors car. And people are not willig to loose the stock condition.

Ein großes Hefe-Weizen, kommt sofort der Herr. ;-)

keynote22

heh ya but I actually own a pair complete with suspenders lol. My family--great grandpa--is from Denmark I want one of those little hats with the feather heh heh. Von Trap family singers and all!!! Good news guys. I tried maxelle, Maxelle professional whites, maxelle professional golds eftec, fuji, and walmart brand. The maxelle professionals both play but the golds skip a few times when I hammer it around corners, the whites never skip. My previous cd-rs where el cheap o no names. You can see throught the golds but not the whites--not sure if that is what makes the diff but it does work now and that is all that matters!!! You rule Tobias!!! Saved me from buying a fm modualted cd changer.

keynote22

ok next question. Let go back to your original pin and wiring comment.....My nakamichi has aux inputs so I can hook my roxio mp3 player into it. While I was debating about fm modulated cd players I found cd/mp3 players that needed a cd-r disk to work but no fm modualted solid state players that cost under $700. How can we hook a roxio or similar walkman style mp3 player into the bose system? Those things are so small they would fit in the ash tray and hold hours of music LOL. I was wonderind about splicing into the inputs to the head unit from the cd player but I figured there had to be more to it than that. What do you think?

RX-7-Tobi

Hey hoh,
I did not understand your leather things. Have to check with my dictionary. ;-)
For my Sony Home DVD I use ultra-cheap Walmart CDRs. I can't remember the brand name now. but it's the only CDR he can read.
FM mod. is no the best sounding solution! ;-)
The easiest way to connect your MP3 player is to look for an Stock 6-way CD-changer from the Mazda FD add-on catalogue. ;-) It has a 1-DIN controller that fits in the second DIN-place where your 1-CD-player is now. It looks very similar. And has a front-aux in! But I guess it was only available for German/European FD owner because they had no stock CD capabilities. And I guess no 5 pieces of it where sold, because only 200 FD are driving around here.
The other way is to modifiy the wiring, but I'm not sure whether you wanr to do that.
Let me know.
I will make a scan of the (German?) CD-way.
Take care,
Tobias

RX-7-Tobi

Hi, here comes the 6-CD-changer-picture.
Was it available in the USA?

keynote22

wow that is great. I'll have to see if I can get one. I belive it was available in the US. I wonder if a new one would be 10 years old or if they are making them with newer technology now that read burned cds better...

here is a hat with a feather like the von trap family singers--you know "the Sound of Music" movie?? I think I need one of these hats to go with my lederhosen. And all american do wear blue jeans and cowboy hats and carry guns. At least were I live they do. :0 did you mean that you didnt understand heh heh? That is the same as ha ha or just me laughing at my self.

RX-7-Tobi

Hi friend,

I checked my dic and undestood. All Lederhosen have Hosenträger. And that what'S on the hat is no feather, it's a Gamsbart. Some hairs of a animal that lives in the mountains.
Yes, and all Americans drive pick-ups consuming more fuel than five German sports cars. ;-)

Be carefull by buying a new Mazda aftermarket CD-changer. Car manufactures change the OEM-producer very often.
The FD stereo system was made by Panasonic. It needs a 13 pin DIN connector. But I guess even different Panasonic have different connectors. So be sure that it will fit the FD factory system.

Heyho
Tobias

P.S.: What's a "trap family singer"?

keynote22

you are really informed on your stereo type bavarian fashion. suspenders = Hosentrager? i new that was a gamsbart and I also knew it was animal hair--I just didnt have a good picture of that
style hat.. beppo? or gregor? Im not sure.... So, I have an audi a4 and a mazda rx7 and I dont own a gun or a pick up truck but I do have an 88 montero suv so I guess Im a nasty american capitalist after all. Only only drive it off road though So I am not global warming too much. And I am helping your ecconomy a little by buying genuine german parts for meinin Audi. And I did date a german girl for a short time--Anna, do you know her? Ha ha ha ha ha ha ha she was trying to teach me german--my favorite word was streifenhurkin...??? spelling?? is it the same thing as gestreiftes Eichhörnchen lol. She was great

There is a very famous movie called the "Sound of Music" with Julie Andrews from the mid 70's they show it on television like crazy this time of year--its about a nun that is a nanny for a family in Austria during WW II. The children have lost their mother and they have a strict father. She teaches them how to have fun and be in love again by singing. The father is drafted into service but he disagrees with **** ideals so he will surely be put in prison or worse!! They escape from the ***** by entering a singing contest and then slipping away into the Alps during the commotion of the contest. The family is the "Von Trap" family and they enter the contest as the "Von Trap Family Singers". The end of the movie shows the entire family on a beautiful mountain side in a field of edelweiss. They are all wearing hats like the one above--I guess it would be similar to saying Americans wear cloth John Wayne or Clint Eastwood style---I am guessing those are american stereo types you would be familiar with?? The Sound of Music is an american movie. Although I realize they change the names of the films when they cross the ocean--I figured it is a movie that would have been around the world by now. I love German movies--Im not sure what the German titles is but Run Lola Run is cool. Hollywood tends to miss something when they remake German films. It is never as good as the original Although Hollywood can make a great film about spaceships and explosions...

I really need to get over there some day--Neuschwanstein, Heildelberg, Frankfort--you have some really beautiful areas over there. I was supposed to go to Switzerland last March but things didn't work out. I'm going to have to wait to travel overseas again--as you know American is not so popular around the world right now. It is a good time to stay right here.

Guess I better get back to Mazda business....I'll have to talk to Mazda about the CD changer. I'll keep you posted. What did you do to your center channel on your web sight--add a frequency filter to take out lower frequencies? I can get some of the words but not many. I really like the Bose system but I'd like for the bass tube to be a little stronger at lower volumes. It doesn't really seem to work too well until the volume is turned up about half way.

RX-7-Tobi

Yes, suspenders is Hosenträger ("carry the trousers").
Hey man, I'm gonna show you what a real Gamsbart looks like!

;-)

You met a German girl and talked about Streifenhörnchen?!? ;-)

I don't know the Trap movie. But I guess it has to be real hard stuff when Americans make a film about the Germans in the Alps. ;-)

The movie you noticed is "Lola rennt" (Lola runs).

Let me know what they told you at Mazda. I fear they will have no idea. ;-)

Did you tryied to have your headunit playied without the cd deck? A guy says the total system does not work then. That is strange.
https://www.rx7club.com/forum/showth...hreadid=132347

Yes, I did a frequency filter on my website. The German audio system has no center amplifier and so gets the full bass that it can reproduce but that reduces power handling and sound quality.
I hope Bose did a good job and did a active crossover in the amp.

So the bass is to weak at low levels?
How low levels?
That is a fact that humans don't hear all frequencies similar good.
We hear best at about 1-3 kHz. So low and high freq. must be very very louder to seem as equal loud as mids (sorry for my poor English).
And what is even worse: It changes with the volume. So at lower levels we hear bass even worse compared to mids and highs than at higher levels.
Thats why we have Loudness. But 99% dont work as it should be. They do a fix bass and high boost, no matter how loud you play.
A proper Loudness would do that at low levels and reduce that boost the louder you hear.

You should set up the bass gain to the level you hear most times. If you hear more or less loud, you have to change settings. Sorry guy, no other solution possible.

What A4 do you drive? Do you know the RS4 with 380 PS?
I drive teh FD and a VW Polo (USA:Fox) G40. It has a 1,3 litre engine powered by a spiral ("G") supercharger. Has stock 113 PS and 800 kilogramms. Now about 140 PS;->.
It goes 0-60 mph in under 7,5 sec. :-)

Does anybody know Phase Linear Aliante subwoofers in the USA? That are the best sounding subs worldwide. I have one. Never heard anything better.

RX-7-Tobi

I found a mistake:
Yes, I did a frequency filter on my website. The German audio system has no center amplifier and so gets the full bass that it >> CAN'T << reproduce but that reduces power handling and sound quality.
I hope Bose did a good job and did a active crossover in the amp.

keynote22

Wow, there is a Geissbock on that hat. Ya, Streifenhörnchen--we were speaking french together and started talking about words that were fun to say. Streifenhörnchen is a fun word to say--lol what is the difference between gestreiftes Eichhörnchen and
Streifenhörnchen. Geburtstag is another fun word--lots of hard consonants--russian has a lot of words like that. She could cook--wow now I am starving-- spatzel mmmmmmmmmm

Mazda said the cd changer is still available but it is $700+ more than I want to spend on a factory cdplayer. They were only available for model year 95 although they could not tell me what the difference was between 93,94,95.

Thank you for the information on bass gain--you are correct that I can not hear the bass and lower volumes. I wish the system had a front to rear fade. The center speaker is always too loud and I can never hear the rears. Once I turn the volume up half way it evens out.....

My audi is a six cylinder no turbos. They do not have the RS4 in the states but I am very familiar with it--drool drool. I almost bought an S4--250 hp twin turbo, but it was just way too expensive, The American Audis have very very soft suspensions so I could not buy a new audi s4 just to have to change the suspension. My a4 was a 96 and very cheap to buy so when i put the bilstein suspension package I bought from Germany, it did not cost very much. I looked at BMW m3 and z3 m too but also too expensive for the performance you receive. well the e46 m3 is really a great machine but it costs as much as a house. Ferrari 308 was also a choice but not fast enough and too expensive to maintatin. Can you send me a Lotus Elise or a McClaren F1?? FD is best car for the money!! plus it looks so cool Audi A4 Quattro is a nice car, good for snow and long trips, but to slow. You guys always get the best cars--even ford are better over there!!! you get the cosworth, we dont get cosworth!! We get junk. Even the Fox was junk...Supercharger on your car--factory??? I bet it has a great suspension too. I thought everyone over there drove a Ka or a Smart unless you own a castle and drive a Mondeal.

I have heard of Phase Linear but it is not main stream here. Sony, Alpine, Pioneer are sold a lot--Nakamichi is most well known high quality. I like Bose car stereo and Nakamichi--very simple and clean..most sonys have too many buttons and are more like video games than quality audio. For home system--Linn, Arcam, Rotel is what I like. Most people buy Sony or mitsubishi. Most American think louder is better and more shiney lights and buttons is better

Im getting off topic pretty bad so feel free to email me at Keynote22@yahoo.com. Maybe we can trade something American cool for something german cool--I should send you pics of my rx7 toy collection.
