Notes on 4-ohm bridged / 2-ohm dual operation
Posted 08 February 2011 - 10:52 AM
XLS-D (old): The 802 model technically needs a 20-amp power supply to run this way. The old XLS series tends to overheat anyway with these loads, so we don't recommend doing it.
iTech/HD, MAi: These amps run on an extremely high voltage rail and will need to current-limit to run on these loads. So power begins dropping off below 8-ohms bridged/4-ohms dual.
Update 6/28/13 by Avi:
XLi series amps don't support 2 ohm stereo or 4 ohm bridge!!
Note on combining 2 or more 8-ohm speakers in parallel: There will be spots on the impedance curve, usually just above and below speaker resonance, where the impedance will be BELOW 8-ohms. Therefore, the amp will actually see a load LESS THAN 4-ohm bridged / 2-ohm dual when combining these speakers in parallel, and may react badly to it. Just something to be aware of.

How about running them in series/parallel to keep the impedance up. And if so, I never saw any body talk about reversing the wiring on your Speakon connectors so they would be + to - (series) instead of + to + (parallel)?

im running the amp in bridged mono with the wires setup asper the specifications of the amp i rewired the speakon wires to match whatever the amp needed

It's going to enough but , you won't get 100% of the juice out of the subs.
