Soundstream Granite 180.6

[KriszXJR]

My old Soundstream Granite amps speaker output levels are very different.
I tested all channels with many heads, and all heads from all oututs, but still the same.
The biggest difference there is 5-6 channel.
What could be the error in amplifier?
Thanks for the answers!

Are 5 and 6 equal?

Are you feeding the inputs for each channel directly?

Is this a new problem (were 5 and 6 equal to the others then suddenly lower)?

Do you have all channels set to full range?

Are all gain controls set to the fully clockwise position?

5 and 6 the most different!
But the 1-2, and 3-4 channels have noticeable different.
Yes, at first I thought the problem in HU outs.
But no....
Yes, set full range and stereo mode.
Yes, i turned max position all gain controls.
Thanks!
