Tried to run it all from the DSR1 but found the limitations frustrating so the fronts go to the DSR1 and the rears to the DSI-2. Working ok so far, have crossovers and gains set but feel like I need a tune...or tunes .
I have to ask....how many speakers and amps are you running to require 2 dsp's?
I currently have 10 speakers on 3 amps with only a DSI2.
