And so it came to pass, on 01-13-97 20:35,
   that Shayn Wilesmith spake unto All :
 SW> 1. Is there a limit to how many speakers you can run off one amp ?
Yes and no.  As long as you keep the total load within the amp's tolerance 
range, you can (theoretically) add as many speakers as you want, in 
parallel/series combinations.  In reality, the available power must still be 
divided up between the speakers, and eventually the law of diminishing 
returns takes over.
There's also the interaction you'll get between multiple drivers and their 
crossovers; the effects may be undesireable.
 SW> 2. If there is a limit. would a larger amp be the answer ? as then 
 SW>   there would be more power ?
That would only allow you a little more leeway before the effects of the 
extra speakers are negated by the splitting of power.  It would be better to 
simply add MORE amps (as in, one for each pair of speakers).
 SW> 3. On my home stereo, I have the normal speakers which I guess are
 SW> 8    ohms, I have added two moer speakers which are 4 ohm. Can this
 SW>    damage the system at all ? It is a very cheap system and I don't
 SW>    think it would really matter.
If it's a cheap system, it probably doesn't have the capacity to handle small 
loads.  An eight-ohm and four-ohm speaker in parallel gives a total impedance 
of about 2.7 ohms, which is probably well below a "cheap system's" 
capabilities.
 SW> 4. If you want to put a lot of speakers on one amp, is it better to
 SW>    get an amp with more channels ? Say 4 or 6 channels ?    Is this
 SW> a way to get more speakers onto an amp ?
Yes, or as I said, just get more amps (which is, in essence, the same 
thing... a six-channel amp is the equivalent of three stereo amps sharing one 
power supply).
