Hi, you can increase value of feedback resistors: R6 R8 R11 and R12 to increase the gain, from 20kohm to 40kohm for example. Too high value may increase noise.

I'm using T1X4 amp with miniDSP crossover. I have a problem with input sensitivity of the T1X4. miniDSP puts out about 0.3VAC max.. this is not enough to drive T1X4 sufficiently. Is there a way to increase the input sensitivity of the T1X4?
