Gentlemen,
It's been a while since I have been here, hope everyone is well!! Sorry for the long post below but I wanted to be as detailed as possible with my system.
After many months of my sundown E8 ver.4 sitting in my apartment I finally got around to installing it.
Here is my current system, then I will ask my question
A slightly older pioneer head unit with (4) pioneer TS-G1644R speakers. 1 in each front door and 2 on the rear deck. All 4 speakers run off the head unit (no amp for these).
For the sub I have a JL Audio e1400d running (1) sundown E8 ver.4 sub. LPF is currently set to 80, base boost is off. We will get to slope down in the post. The gain has not yet been set the correct way so for now the gain is maybe a tad over 50%. I do plan on setting the gain correctly in the next week or two.
4ga power wire from battery to the amp with an in-line 40ANL mini fuse as recommend by the amp manual.
The sub is housed in a custom made ported enclosure fabricated exactly to Sundowns specifications which I took from their website. The enclosure is fabricated from 12 ply birch.
My H/U is current set at 80 +2 (I don’t know what the number after the 80 represents but a friend said to put +2 for the time being). Subwoofer #1 setting is to normal. Loudness is off. Base is set to +3, mid to +5 and high to +6
For the life of me after doing some research today, I can’t seem to come to an understanding about slope.

My sub amp has the following settings: OFF, 12DB and 24DB.
Can someone please advise what setting the slope should be on based on my current system and sub size and why? I read today that people with closed enclosures tend to use 12 and people with ported enclosures tend to use 24. I don't know how accurate this is so I didn't put any weight on it.
How does slope affect how the sub performs or sounds? The stuff I read today really confused me.
If one uses a certain slope, does that mean the LPF should be set differently?
Any help would be very much appreciated as I am very confused or over thinking it.
