I just intalled a new Blaupunkt CD/receiver head unit to replace my stock Bose
cassette/receiver in my 1990 Acura Legend LS.
I have everything working, except when I accelerate now I hear a whining noise
coming for the speakers -- the faster the acceleration, the higher the pitch.
I can drown it out by turning up the volume, but it's there if I turn the
volume to 0 (and I can hear it until I make the stereo pretty loud).
Anyone know what might cause this?

ok, i just installed a head unit - Panasonic c3301u and an audio vox amp and some cheap subs. I ran the power wire down the right and the RCAs and remote turn on wire to the left. ok amp turns on, headunit is on, buit no sound from the subs. yes, they work they went from one car to another.... but when i turn the volume up the "whining sound" start and doiesnt end til either the head unit is off or the car is off. I don't know what it is. i have checked my wires twice.... thanks bob

The only way to play an mp3 player through this head unit is through an adapter. You will need to go to Best Buy or some electronics store and buy a cd-to-cassette adapter. You just plug the adapter into the mp3 player's headphone jack and insert the cassette into the head unit. Let the cassette play and play your music through the mp3 player and boom, you have a mp3-capable head unit.
Since you've been trying things for so long, you may not mind another, unless you've tried it already.You'll need someone to help you.
Try using a volt meter on the main power to the changer. (If the changer is din mowered only, this can't be done) and when toy power up the head unit by ignition or other method, read the voltage on the main power wire (yellow?). Tell me what it shows. Also, the "turn on" wire for the unit is usully in with the data cable to the unit, and won't be able to check that.
Also try to read BOTH the acc AND the power wire on the head unit while turning on.
When you read the voltges, make sure that you use the ground ON THE CHASSIS of the componant that you are checking. "Maybe" you have a voltage variance like you said d to a weak ground at one of the units? I'm just troubleshooting as I would if you had brought it to me. Let me know again. Thanks.
** Note- Have you actually reset bothe the head unit and changer?
The Bose system in the Z is wired to control the entire car's speakers. Each speaker has its own amplifier, and the OEM head unit puts out a line-level signal to each amp. Your Clarion unit puts out speaker-level signal (in effect, an amplified signal), into the Bose amps, and it's probably overdriving them and putting them into shutdown.
Your best bet is to replace the Bose speakers with aftermarket speakers meant for a speaker-level drive (which is what I did in my Z, and never once regretted it). If you do so, you'll need to run new wires to the speakers, or if you use the OEM wiring, you'll need to unplug the amps and run the wires from the amp harnesses directly to the new speakers. I think there is an adapter harness you can use that will tap into the line-out jacks on your Clarion, so that a line-level signal can be sent to the Bose speakers - I'd do a google search for "Metra harness 300zx" or something along those lines (Metra makes the lineout harness adapters - I use one in my Audi).
I just took a 6 CD changer out of my 1993 Audi with a Gamma Bose CC as well as the adapter box. I am interested in selling it (I traded the car). If you are interested in the changer, let me know and we can exchange contact information.
Exactly a minute after you turned it on it went out, did it go out with like a bang or spark, seriously, this would indicate that the wiring wasn't correct somehow, i know u checked the fuse for the correct ampperage required and the most important question do you have an amp because most aftermarket head units aren't wired for 6 speakers,unlike oem Bose unit which has a built in amp and 6 wires output, you should have rca jacks which requires a amp for the additional output speakers. I could be wrong regrding how many output available on your new head unit.
