Really? I still have mine run in Network, didn't realize there was a need to switch it over. But if there is, I'll switch it.With the DSP, you should be running the HU in "standard" mode, and not "Network" mode ... in case you aren't already. That 1.25k @ 6dB high pass is there as a protection for the tweeters, since in Network Mode, only tweeters would be connected to those channels.
I ran mine in Network mode for years, and only recently switched it over to Standard after installing the Helix DSP.
For my routing, I have the front signals splitting to the mids and the tweeters in the DSP, and I have the rear signal going to my rear fills. And of course, sub to sub.
I did it this way so I could maintain fade/balance control at the HU, but after installing the Conductor remote control for the Helix (which allows for rear channel attenuation), I really don't need the fade controls in the HU afterall. My install is already finalized though, will all cables neatly tucked and ran through the car; so I didn't see a reason to not use all 3 pairs of RCAs. If you are still planning the final run of cables ... and the 2600NEX has a full range signal on one set of RCAs ... then you could absolutely get away with just running one pair from the HU to the DSP
I just Googled that remote, very nice! I bet that's slick. I just installed the DRC-200 last week and I love it. I'd rather have the 205 with the incorporated LED, but it's hard to justify that expense when I still need basic audio equipment.
I'm jealous that your install is complete. Any pictures of the final setup?
I'm trying to find a way to secure my amps down so they're a little more theft resistant, but haven't had any grand ideas on how to do it yet. Trying to avoid paying someone to do it for me. Toying with the idea of using steel cable to limit smash-and-grabs.
