I am digging through the Service Menu to find a fix for weak bass and found a couple of settings that I wonder what the settings that I need to know what they mean.

LFE Cutoff - This sounds like it changes the crossover point for the sub but not sure what it means.
AMP Pre-Out Compulsion Output - I am guessing sub out? The word Compulsion sounds like it means something different though.

I try saving different settings on the LFE Cutoff but it never saves. Just goes back to 0Hz. It has a little more punch at 80 Hz and 100Hz settings but it won't save. Is there any way to save this setting so that the system, has more punch? I don't want to go after market sub for the extra 3 dB boost needed in the 40-80Hz range for the kick drum. I don't want to make this boost change on my iPhone. I want to have systems matched to locations and not have to change my phone for every location.

 

Also saw these and was curious about them. Forgive me if it's not exact language because I didn't take a pic but toggling them I didn't notice a difference.

DSP on / off
Flat Equalizer (or w/e) on / off

 

I am going to try toggling the other settings today as well. From what I am seeing the LFE Cutoff seems to change the crossover point for the sub and give me the 3dB boost I am looking for when I move it to 80Hz. Just no way to save it. Called Acura and no info on how to save these settings. Maybe I need to work at Acura for a week to get a service manual lol! Cannot seem to find one online.
