I have a 4 channel MTX amp that I'm using to power my highs. The problem is that the back 2 channels are way too loud, be distortion freee. I've already set the gain to zero and they are still louder than the front 2 channels. The front is currently at half gain and the back is off. I'd like to lower the back to even things out but the amp just won't be quiet. It's at the point where my highs are drowning out my subs. Could the amp gains be broken? Any ideas? Doesn't happen that often that an amp puts out more than is wanted.
Thanks for any tips you might have.
