Ok, I am not pressed about the "function" of the DSP, I do however want to use the amp to power the speakers in the dash.

I have two additional amps that I would like to add to the system. I would like to tap the speaker level inputs from the head unit and convert them to RCA level. So, if that means I am goind to 86 the DSP, then its gone. If I can't use the amp to run the speakers in the dash, then I will find another work around.

I agree with everything that has been said to date. The DSP system blows and I don't use it. I don't want to give up the way the rest of the system functions. Volume controls or station display.
