Single SI HT 18DD4 with Inuke NX6000D wiring Q

I have a single full marty built so I can baseline our basement theatre as I add layers of sheetrock. I thought I have everything correct until I tried it and got virtually no sound. It might be the Denon or inuke settings, but I saw something about another DVC in a recent thread. (maybe a UM18-22 thread?)

On an SI HT18d4, do I use the top or bottom wiring scenario. I went back to the12volt.com and I can't tell where the jumper wire is supposed to be. Between the red and black post on the same side or opposite sides of the speaker?

Bottom.

Top will be powering one coil, and shorting the other.

For D4 don't you want to wire in parallel to provide a 2Ohm load to the amp?

Sub builds: Yet another Infinity 1260 build | Twins! | Modified V.B.S.S. build | UM12-22 builds | AV stand and sealed UM18s

Speaker builds: DIYSG HTM-10 build | DIYSG Volt-6 build | DIYSG Fusion-8 builds

I think I read it is not 2 ohm stable. But with all I read, I am only now learning what this all means. I just hope I don't fry the coils running only 1 full marty on channel A.

While I'm at it, do these look right? I am currently using a Denon 4520cl --> inuke NX 6000D --> 50ft speakon cable --> full marty in the basement directly below. I just want to measure what the living room hears and and what the basement hears prior to adding sheetrock, not dial it in yet.

Ahh yes, true. I forgot the 6k is a pair of the 3k bridged so not 2-ohm stable, my bad.

As you were...

Set your limiter to the rms wattage of your sub and you shouldn't need to worry about blowing your sub.

filter 1 should be an -4 at 20hz and HS12, with the main gain set to +4

Thank you, will finally be able to test today.

Does the dual or stereo matter if it is just one sub?

When I set/load the gain in the software to the amp, where should the dial be on the amp?

Doesn't matter if you're only using one channel.

Those knobs are input attenuation, they should be set so your just at/below clipping at your max listening volume.
