Just when I think I am getting savvy, I come up with another dumb question. When I wire speakers in series or in parallel (or both), I am changing the ohms resistance of what is on that channel. In the case of the XLS1000, I can fulfill the following scenarios:

1. 700W x 1 @ 8 Ohms

2. 350W x 2 @ 4 Ohms

3. 175W x 2 @ 8 Ohms

In the case of the two XLS1000 amps for the four subs, I am putting 350W x 2 @ 4 Ohms. In the case of the two XLS1000 amps for the eight surround speakers, I am putting 700W x 1 @ 8 Ohms. Finally, In the case of the two XLS1000 amps for the four rear-surround speakers, I am again putting 350W x 2 @ 4 Ohms.

My question is; does the amp automatically know the ohm resistance of what is connected to it and adjust the wattage accordingly, or is there an ohms setting on the amp that I have to adjust (I do not see one). So far, I have been working under the assumption that the wattage that makes it to the speaker is automatically dependent on the resistance of the driver.
