 jumping speakers
is it a bad idea to hook 2 speakers in-line from one terminal on the
reciever?

You can hook up whatever you like as long as the total impedence of
your speaker system is not lower than the minimum rating for the
amplifier.

If you want a more specific answer, ask a more specific question.

If you connect the speakers to only one terminal, you won't get any sound.
The speakers have to connect to both terminals.

Damn you, Sommerwick! I'd laid a bet with that Mr. Crowley would be
the first to post that particular comment! :-)

If you parallel speakers, you reduce the load impedance the amp sees.

If you put two 8-ohm speakers in parallel across an amp, the amp will
see a 4-ohm load. If the nameplate on the amp says "Minimum load impedance
4 ohms" this is fine. If it says "Minimum 6 ohms" it is not.

If only it were this clear cut. If an amplifier said "Minimum 6 ohms"
and really meant it, an 8 ohm speaker would blow it.

What really matters is what has already been said. If you never turn the
volume up high, don't worry about it - nothing will break. And as a
corollary if you ever do turn the volume up high enough for it to
matter, then it is way underrated anyway, and a much bigger amp and
speaker are needed.

I think you just blew the OP's mind actually.

Perhaps I should have expanded a little, do you think?

Then there's the likelihood the receiver's source impedance is nearly zero
ohms and it really doesn't matter. I once encountered a Crown D-75 driving
the ground system of a TV facility. Sound continued to come out of the
speaker, but all the video was modulated by it as well!

Is there any chance when he says "in-line" he means in-line? Nah,
you're right :-)

But if one of the speakers is 4-ohms, things get interesting. The load
doesn't go down all that much (3.2-ohms), but the 4-ohm speakers will be
louder than the 8-ohm ones.

That's funny, I got 2.7-ohms.
