How does this sound to you

but all maxvla needs to know is:
Ohm's Law?

V=I x R
where
V=voltage
I=current
R=resistance

and to know that wiring multiple loads(speakers) in parallel results in a subsequent drop in resistance equal to the results acheived by this formula:
1 1 1 1... 1
--- = --- + --- + --- + ---
R r1 r2 r3... rn
where
R=overall resistance(that which is "seen" by the amp
r1=resistance of first driver(loudspeaker)
r2= " " second " "
r3= " " third " "
rn= resistance of nth driver

so you can see that for a fixed voltage "I" is inversely proportional to "R". decreasing R increases I... to a point. There are physical limits to the amount of current an amplifier can pass, and that is where the circuitry issues come in, and I won't pretend I know anything about that...

Hope that helps... from everyone's favorite newbie(j/k),
