So I purchased a Helix Mini DSP with 6 channels. My thought was running 2way active upfront using 4 channels. Then using the other 2 for subs and running passive in the rear. I’m using the Navtv Zen that outputs 12 flat channels. So I was planning on running 2 channels to the helix and another 2 to the amp running the passives. The person who I planned on helping me with the tune said this won’t work. Has anyone done anything like this.
