You have 6 speskers off 4 channels.
Can you take the two 5" speakers away and see what happens?
How loud are you driving them?
Can you take 2 away, so you only have 4 speskers please?
The load on 2 channels is too high, (low impedance).
You have 2 speakers off one channel twice, and if they are 4 ohms each, you have a 2 ohms load per corner. They may be small, but the impedance is too low.
Who makes this 2000w amp?
That would be peak at 10%THD.
RMS would be less than that.
The amp is working too hard.
Just reduce it to one speaker per corner for now.
Do you need any further help?
I hope my advice has been of assistance to you.
