Whats wrong with my system

[disarmamant]

I don't think the speakers are out of phase but i will certainly try them the other way around since that is a very easy thing to do.

When the speakers are out of phase it means one speaker is not in the same phase as the other, the speaker cables are connected the wrong way round in one channel only.
With the dual mono amplifiers it’s easy to get the phase wrong in one channel because both the plus and minus speaker cables are plugged into the red speaker terminals only on each amplifier.
