Amp to speaker over Cat5e data cabling?

[Superficial]

Hi there,

I've heard a lot of people talk about how useful Cat5e can be to send audio signals down.

Is it possible to use a free RJ45 data socket to send music to a speaker in an, otherwise, difficult to wire room.

Basically can I substitute speaker cable with data cable and some kind of RJ45 --> PA speaker adapter (appreciate that this may just be cat5e cable at one end and exposed wiring at the other) at each end?

any experience or suggestions?

thanks

Thanks for the replies so far. The actual length of the cat5 cable is probably less than 30 feet.

The speaker will be in a small office used to receive clients - so long as it's audible that should be fine.

If people still feel the volume will be insufficient couldn't a powered speaker help?
