Parallel Speaker hook up....?
Now based on this image located here...

Does the 8 ohm indicate the total speaker, or individual drivers?
I have 4 drivers in each cabinet. There are crossovers, so speaker read 8 ohms at terminals.
Will this be a true 4 ohm load?
Its nice to have a quality product that is stable at 2 ohms, but only going 4. Thanks for clearing my mental haze.

8 ohms is the "nominal" impedance of the speaker system: the combination of drivers and crossover. But the word nominal is used because it is only an approximation. The actual impedance varies throughout the frequency range. Many so-called 8-ohm speaker systems dip close to 4 ohms, and this dip usually occurs at lower frequencies, where power demands are highest. A simple ohm-meter measurement only measures DC resistance, which does not reflect the actual impedance of the system.

The picture demonstrates a 4 ohm load. The 8ohm label is on the entire speaker normally and the 4 ohm resistance is what is being measured at the wires going to the two 8ohm speakers.
Be careful though if you have 4 8ohm speakers wired up in parallel you will be drawing only 2ohms which could damage your amp if it wasn't designed for it. Always try to match the ohms with the amp. If you cant get it exact go for a higher ohm and your amp will run cooler.
