Hopefully you're not using the RCA inputs on the AudioPower amp and you are feeding it both left and right high inputs?
As for the sub, Is the Behringer amp set for normal operation? No Bridged or filter switches set? Is the speakon cable wired straight through pins 1 -1 and 2-2? Do you have the crossover set for typical 2+1 operation, 80-100hz crossover frequency?
From the crossover, I connect to the RCA inputs on the amplifier that is running the two side speakers. Not really sure how to set the 2 + 1 operation.
The amplifier doesn't have XLR inputs. The only XLR provisions above are labeled (R Bal Line Out). I don't think I can use these for my input. I am reading the manual for the second time now, although a few things have still failed me for now.... I will blame my head!
The crossover is a cx3400 and amp to the sub is inuke NU1000 and the second amp is the Rock Audio-10000 for powering the other speakers.
The cable am using to the second amp runing the two side speakers
For the crossover you only need to concern yourself with the section for stereo 2-way operation.
On the back of the crossover.
Set the XOVER FREQ button to X1.
Set the MODE buttons to 2-way stereo.
Set the LOW SUM button to on or pushed in.
On the front of the crossover on both CH1 & CH2.
Input level to O or straight up.
XOVER FREQ to about 90hz or a little past 9 Oclock.
Low Output Gain at O
Low Output Mute off
High output Gain at 0
High Output Mute off
You only need to connect 1 cable from either one of the low outputs to the sub amp but you need a cable from each one of the high outputs to the AudioPower amp if you want stereo sound. Don't concern yourself with the phase invert, delay, or CD horn functions yet just set both channels the same. Also don't worry about the limiter functions yet.
On the back of the NU1000 amp make sure the crossover is turned off and the mode switch is in stereo, and on the front set the level controls all the way up.
