PUNT

becouse the cd changer dose not have unough power to push the speaker

Check your wiring, separate the power and ground wires. Keep them apart from each other. Make sure Both grounds a tight, and separated too.

In the last 10 or so years, Sony has only made two different magazines for their 10 CD changer units that I'm aware of.

The changer has a mechanical slide system inside it. It may be binding up around those positions. You may want to take the cover off and reposition some of the excess grease into those slide tracks and try it again. Or you could just be happy with a functioning 7 CD changer.

You can order them on-line from Sony Parts and Accessories - and they are reasonably priced - around $35. I just ordered one last week and received it already!
