In Topic: XTI4000 Phase reversal

Hello and thank you for the quick response. I have tested all three amps in bridge mode with the same reference source. They will all play fine until the polarity reverses randomly. I can go into the xover in band manager and manually reverse the polarity and it will play fine for awhile then do it again randomly. The sound difference is like night and day, there is no question as to when it happens. I have even ran each amp on a separate branch circuit thinking I was loosing AC voltage. As long as I'm just using one of the bridged amps it plays fine with no cutting out. The minute I use both amps that are bridged the problem begins. So I know the reference material is good.
Is there a good shop near Fort Myers, Fl that can take a look at these amps and see if they need to be repaired?

Just an update, I have installed two brand new display boards from full compass in my two XTI 4000's with a mfg date of 2014 on each board. The bass still wanders in and out of phase and sounds like crap.  
Any one have any other ideas as to what is happening with these amps?

I bought one new board and put it in the oldest amp. There is no change with the problem. I'm going to try and switch out my top cab amps board with the other xti 4000 and see what happens. I don't have the money to waste on all new boards when I'm not sure it will fix it. I will try the mono signal and see what happens.

I pulled the tops off and all of my amps have the version 5 display boards. So back to square one. One amp was built in 2009 USA and the other one in 2011 in China.

Thank you very much Alain that sounds like it would make the most sense. I will open up the cover and see what version I have. It also seems as these amps get older the problem gets worse, they used to play all day without any issues when I first purchased them. I will post back when I verify this.
