Harrison Labs FMOD Inline Crossover Pair 50 Hz Low Pass RCA
Sorry if this has already been answered elsewhere... But does it have to be between the head unit and the amp or can it be placed between the amp and the speaker?
This is a line level filter that goes between the source and the amplifier.

I currently have the 50Hz low pass on my subs. If I add 50Hz high pass on my mains, will that create a smooth crossover? Or should I try 30Hz high pass? Do the high pass ones affect the sound at all? I don't want to decrease the clarity of my system.
The actual effect will really depend on the speakers in room response, but I think I would go with the 50 Hz high pass over the 30 Hz, I usually try and keep the crossover points consistent.

How are these oriented? Does it matter? Is the input the female end, and the output the male end? Or the other way around? I may need a gender changer depending on how this hooks up.
In my experience the orientation matters. They are directional. Input is female end so that they are on the end of the interconnects going to the subwoofer amp. I tried flipping them over and plugging them to the output of my pre but that destroyed the soundstage and degraded the sound quality due to too much hf going to the sub.

How does it work using them with a 1-to-2 Y-cable?
If I use a mono-to-stereo RCA cable and put one FMOD each on the L/R stereo ends, is that the same as stacking 2 end-to-end, doubling the slope to 24dB/octave? Thanks in advance!
Unfortunately no, the FMODs much be stacked in order for the slope to increase.

if i use 2 f mods 50hrz low pass together will it now become 25hrz?
No, I believe 1 F-Mod has a 12db per Octave slope, if you use 2, it will still be 50hz, but it will be at a 24db per Octave slope.
