[QUOTE="joey toribio, post: 216734, member: 15637"] Agreed, it's not dirty switches. 4 individual switches can't all fail and resolve simultaneously on 4 amps that were tested both simultaneously and then independently. For stereo mode, custom cables were not needed. 1+- cables were used and working previously and then these same 10' cables suddenly no longer worked. The only thing that changed between when they worked and when they didn't work was the date and time. Custom cables wired 1+2+ would be needed for bridged. I swapped cables as a trouble shooting procedure only after the malfunction. I tried the new cables in all 3 modes and only bridged worked. I tried the old previously working cables in all 3 modes and only bridged worked. When the problem resolved itself randomly, both sets of cables (new and old) worked in the 2 modes they were supposed to work in (stereo and mono). The resolution did not come from a system change. It came randomly after some time had passed but no changes were made. What else would change over time that isn't hardware related? AC power is the only thing I can name. I had gotten some brand new 25' cables and hooked it all up just to find nothing worked. I went back to the shorter 10' cables from the day before and they no longer worked either. Identical setup different day. That's when I started trouble shooting and isolating the amps the cables and the speakers to limit points of failure. [/QUOTE]
