Before you are 2x 12”, 4Ω, dual voice coil subwoofers that are individually wired for 8Ω each and then wired in parallel to a Class D mono block amp for a total resistance of 4Ω. The amp is powered by a power supply that’s rated at 12V 125A 1500W DC.
The subs are these: Rockford Fosgate P2D4-12
This will be going into a closet behind my A/V wall.
This will be used in my home theater using a Marantz NR1403 as my receiver (NR1403 - AV Receivers)
My main speakers are these: CBM-170SE BOOKSHELF MONITOR PAIR
Here are a few more pics of the subwoofer itself:
What would be a good baseline to start at? I am not looking for over the top volume and crazy attack like I used to when this was in my trunk.
you can see the amp adjustments in the pic
I would like something more subtle that focuses mostly on super deep frequencies for the movie action.
Of course there will be some Jazz and Death Metal happening as well.
Thanks for reading!!

+1 It has a variable XO (LPF), so just going to say that THX is 80 or 120 Hz for the LFE channel, ergo I'd start at 80 Hz and go up as required if the mains sound in any way 'distressed' at the desired average listening level.
Since your speakers are ported the "subsonic" filter should be set near the Fb (box tuning frequency) to keep the super deep frequencies from flapping the speakers, especially if using the +6dB (x4 power) or +12dB (8 times the power) bass boost.
You can determine the Fb using a sine wave (REW has a generator) signal, the cone movement will be least at Fb, and increase above and below, leave the "subsonic" filter set to it's lowest setting for the test, then move it up to near Fb, probably in the 25-45 Hz range.
