question means that you would not have the technical knowledge to do
this. There are just too many variables to be be able to give you
generic advice as to how to do this. There's no such thing as an
"average" CD/Radio/Cassetteplayer, there's just too much difference
between various types. If you have a proper service manual (not user
manual) for the one you want to convert, with a circuit diagram, then I
and others here may be able to advise you on how to do it. If you want a
cheap PA system, there are a number of Karaoke systems on Ebay which
will do the job.

Thanx to some of you ppl for your info. Serge, I don't have a service
manual (although I could probably get one online somewhere), but it
seems you have some knowlage or 'know abouts', so if u could just
direct me to someschematicsof a remotely averageradio/cd player.
Thanx
Sadly, no. As Graham mentioned, you seem to have missed the point that
there's no such thing as an "average" unit. For example, is the volume
control on your unit passingaudiothrough a standard potentiometer, or
is the volume control controlling an electronic attenuator? Do you even
*have* a physical volume control, or is it an up-down electronic device?
You need to know this, as the simplest way of doing what you want is to
put the incoming externalaudioonto the volume control, perhaps using
switch contacts on the jack to switch between internal and externalaudioautomatically. However, you need to know firstly if the jack *has*
switch contacts, secondly, what sort of volume control you have and
thirdly, can you physically access these for soldering. Many modern
devices use surface-mount components on a multi-layer board, and what
you need to access is buried in one of the middle layers. All in all, a
lot of trouble, when you can buy something suitable quite cheaply
already done for you.
Best of luck whatever you decide.

Thanx for your explination. I hope I'm not been pushy, but I really
want to do this because it seem so ligitimate, I mean radios are every
(almost all having audio out-put) yet they're so diverse & complicated
that everyone has to resort to dealing with expensive speakers of no
portablity.
I just want to have a radio that I can plug my mp3 player into and
have it function like a portable speaker system, so it'll be as simple
as a radio yet I'll be able to have digital sound and a playlist of my
own without having to deal with the inconvience(not so big capacity,
length of burning time, also not all radios have mp3 cd readers) of
burning an mp3 cd.
Also It's a thing of pride, I just want to do it. And I have searched
the internet - using all relavent keywords I can think of - but
haven't found any information on how to do it.
So I guess you don't have more info you can offer? Like maybe some
diagram showing where the exiting audio signal is just before going to
the speakers or where the audio signal is just after leaving the sound
processor on the cd drive. I know this diagram will be most likely
quite different than the wiring and circitry on any radio I have, but
you could state what specific radio/cd player this hypothetical
diagram is for.
Well I guess I am been pushy, but it's frusterating not knowing
exactly how to do this.
