Default Line-out from portable cd player to a speaker?

Hello diyaudio community,

For an artistic installation requiring 8 small speakers with 8 channels of sound I am looking for ideas for an inexpensive solution based on 8 portable cd players connected to its own speaker.

I looked at multi-track playback from a computer and a soundcard capable of multiple outs, but that breaks the budget.

Instead, I am looking at taking the line level output of a portable cd-player and boosting the (mono) signal to a cheap 2 - 4" speaker.

I suppose you would do some signal attenuation to accomplish this... can anyone point me in the direction of some circuits or links?

Any advice is appreciated! Thanks,

If your power output requirements are modest, you might build an amplifier based on the LM386 chip. Absolutely minimum parts and it operates on a single 12 volt supply.
