So I finally did my install. I’ve been sitting on the equipment for 1.5 years. Focal es165kx2 components up front passive currently, the same es165 mids in the rear without tweeters for fill, 2 jl 13tw5 subs down firing, Nav tv, and jl had 600.4 and had 750.1 my Nav... tv seems to work except that I get static out of the rear channels. I am currently running y rcas off the front channel to get a signal for all four channels. Sounds pretty good but there is room for improvement. Will cal Nav tv tomorrow to see if they have suggestions. I have a dsp and will likely go active in the future once I get the bugs worked out of this set up.
