Ok, heres the deal. Me and my friend are having an argument, and we can seem
to figure out the answer. He thinks that an amp can only handle a certain
ammount of subs, even if the Ohms match up. But I figure it this way: You
can have as many subwoofers as you want, as long as it matches the
recommended ohm 'stablism' if you will. eg, if you have an amp that is
say1000watts x 1, at 20 ohms ( i know that its far fetched) and you have 10
2 ohm subs all in series, it would all match... he thinks that it would fry
just because there is too many speakers wired up to it, but I think that the
number doesnt matter, and that it would work just peachy, because the
resistance matches up.

Whos right here? or are we both wrong?

The impedance is all that matters. It has no way of knowing how many
subs there are. If you needed a whole lot of free-air subs, you could
put 8 home stereo subs of 8 Ohms 200W each in parallel on a 1 Ohm 1600W
amp. It might pop your head but the amp would be see its perfect load.

Putting speakers in series doesn't work so well, though. It's
especially bad with the tuned cabinets that subs use. Enclosure tuning
varies the speaker's impedance by frequency so the power won't divide up
nicely. A "4 Ohm" ported sub might be 3.5 Ohms at resonance but 7 Ohms
at other frequencies in its operating range.

You are right.
