Interesting.

So the connection method does in fact determine the allowable loads in this case. And to those contemplating trying that parallel mono mode wiring on other amps: do not try this at home, with very few exceptions. Smoke is only magic as long as it stays in the box.

Totally agree on connection method determining allowable loads Passinwind. At the start of the post though it seemed to me that we were getting hung up on the series versus parallel speaker wiring thing determining the connection mode.

Roger that.

I have a Crown Power Base 1 power amp and will be running it in 'parallel mono' mode into two 8 ohm speakers, wired in series.

Doesn't series mode result in additive impedance, so that two 8 ohm speakers in series would be a 16 ohm load? I think parallel wiring of the speakers would result in 4 ohm.

Yes, that is correct. Series adds, parallel divides. Two 8ohm speakers wired in series is a 16 ohm load. 8 plus 8 = 16. Wired parallel, same said speakers would have a 4 ohm load. 8 divided by 2 is 4. So OP has a 16 ohm load.

Best to read the manual as "Parallel Mono" is not often encountered around here.

I disagree. It’s how I run my bass amp. Power amp inputs paralleled and driven by one mono signal from my pre-amp. One cabinet on each channel.

You safe from that fire yet Charlie?

It's still only 46% contained, but yeah, pretty safe and comfy now. Thanks for asking.

"Daisy chain" WRT electricity is a slang term with no fixed or standard definition so there's no way to be sure your audience will interpret it as you do. "Series" and "parallel" are defined.

This was exactly my point. In actuality, the op is NOT running in series, but parallel by running first to one cab, then to the second. The term daisy chain makes logical sense to help clarify the specific method of connection, in order to help the op with what I (correctly) gleaned was incorrect in his first post.

To my knowledge, although not a technical or standardized term, "daisy chain" is a common way to refer to this way of running cabinets in parallel.

Read the crown manual above for Crown Power Base 1.
It is not what your are describing
The output of the amps is actually wired in parallel, not just the inputs

For a New amps and what's available now read the QSC manual
Invalid Link Removed
Excellent documentation! It explains how QSC is now offering this.

With Crown possibly but for the vast majority of power amps it’s just the inputs that are paralleled.

Not with all crowns. It's rare in older amps.
But it will be popular going forward in new amps. Everybody wants low impedance stability and high power.

I prefer the current state of parallel operation.
