CD Doesn't Produce Audio - BMW Forum

mental · 08-27-2006, 01:55 PM

Guys,
I just bought an Alpine 9856 (it's alright). I installed it myself onto my 99 328is (e36). I bought the harness and just connected the harness with the one supplied by alpine. the only one that was not connected was the pink and blue & white wires. I think I did everything correctly. Now when I was going to try it out, the radio worked just fine. The CD player worked except that it didn't produce any sound. The display showed that the CD was read and was playing but NO SOUND coming out of speakers. What's wrong?
Please assist.
Thank you

take the blue wire (ant remote) off the harness, and hook up the blue/white wire from your radio. the blue wire is antenna only. it only has voltage when the tuner is playing and "lowering" your antenna, hence shutting your amp off. the blue/white off your radio is the amp lead, which stays hot, regardless of the source being played. Hope that helps...

Thank you. Here's what I did while waiting. I realized there was an external amp. I believe the power of the amp was through a white wire attached to the harness. So what I did was I used the blue wire (antenna lead) attached it to the blue and white (remote lead) and just made sure that that connection matched the slot of the white wire in the car's harness. It worked. That should be okay right? Also, when i started using my ipod fm transmitter, the sound quality deteriorated as compared to the business cd. Now there is this high speed clicking sound, like an interference. Why is that? I know I could use the high speed ipod cable. Stores are out of stock. So for now, I'm still using my fm transmitter. Thanks again.

yup i forgot to mention the white wire in the car needs the blue/white from the radio. it is the power antenna (if equipped) and the power amplifier also. on the fm transmitter, try a different frequency if it is selectable. there may be a strong radio station trying to interfere with the signal. i havent used an ipod personally, so im not sure about the differences with the high speed cables available. the fm x-mitter may not be of good quality also, we (in the past) had got and sold some pretty cheap ones we ended up replacing. hope that helps...
