4 ohm speakers

[Robert Chasmer <robert.chasmer@xxxxxxx>]

Over the last few months I've been doing lots of work in my bathroom
building a proper shower to replace the current one other the bath.  We've
installed a steam generator, body jets, normal shower head and a little
seat.  The final thing I'm adding is water proof speakers to run some tunes
whilst relaxing in the steam.  The ones I've gone for a Sony Marine
speakers, primarily because these where recommended by the steam people.

These are car speakers and so rated at 4 Ohms.  I had planned to run them
off a stereo I have in the office with a simple switch to choose
Shower/Office.  Is there anything I could or should be doing to deal with
the fact that they are 4 rather than 8 Ohms.  Should I put 4 Ohm resistors
in series or something?  Will connecting them up directly damage my stereo
or the speakers?

Thanks


Rob

P.S. I did have a bit of a look on the archive but couldn't really find
anything specific here other than maybe having 4 rather than 2 speakers.
Also I couldn't seem to get any results using a grouping search like
"My
sentence" or {My Sentence}.
