Hey fellas, just an update. I got the iNUKE earlier this week. I disconnected the LF portion of each of the in-built 3-way amps and then connected the iNUKE to each of the woofers directly. I replicated the stock crossover settings (i.e., 24db at 600hz) and all is well!!!
Pretty pumped. I need to run some sweeps to tweak overall levels and then play with the dsp but so far so good.
