Think there’s a miscommunication lol, I have not tried nor said it works on my 2019. Haven’t tried yet.
Oh, OK... Can you try it please and let us know if they updated the Syscom module for the 2019 Civics, so it works to control the External Amp's DSP.

( If you need help is accessing the Hidden Menu, and cannot find it on the forum, give me a shout, and I'll post a detailed sequence of getting to the Syscom DSP control menu.)


I am assuming they missed updating it when they developed the Premium Audio system with the external Amp.

So I tried it with the 2016-2018 directions I found on here and that did not work. I’m thinking it’s different with the 2019s. Do you know the method for 2019s?

Does the Lc7i replace the need to use DSP FLAT? or do I still need to use DSP FLAT to get a more desireable sound?

What about a 2017 touring?
If you have the premium audio system (which I believe you do), the DSP is contained within the external amplifier and DSP flat on the head unit will not fix it. You will probably need something like the JL Audio Fix 82 to correct the DSP signal or (better option) bypass the external amp altogether.

Can you share what your settings are on yours? Accubass and whatnot. I'm struggling with the rolloff settings and with the bass knob that was supplied with it. It seems like it takes 5 to 10 seconds to register that there is bass at times.
There's a lot of discussion around DSP, which I have no idea what it's all about, but I'll share my LC2i settings. I have mine installed in a 2019 Civic HB Sport Touring, with upgraded sub to Kicker CompRT, using Pioneer GM-DX871 amp and LC2i tapped into original sub speaker wires. Sub is wired to 4-ohms and is rated at 300 watts RMS, which matches the amp's 300 watt RMS @ 4ohm ratting.

I did initially try what vast majority of tutorials/guides suggest, which is to set Accubass threshold to max and Bass level and Accubass to mid (12 o'clock), but what i found is that those settings, even with my amp's gain to minimum was causing my amp's output to go way over the sub's voltage/watt ratting and thus clipping. As a first timer to the car audio world, this confused the crap outta me. After playing with the LC2i's Bass gain, while paying attention to the maximized light, i found that the level had to be much lower than the Middle setting, more like 10 o'clock setting. But even after adjusting it this way, my levels at the amp were still way too high.

In the end, I settled on LC2i's Bass gain and Accubass levels pointed to the left (9 o'clock setting) and left Accubass threshold to max (I should probably tune the threshold properly one day). Even at these settings, my amp's gain is still set to absolute minimum.

One thing I'de like to mention about what I found; I first made adjustments using a 50hz test tone and a volt meter as well as listening for clipping. But when I started playing music, I noticed the types of songs and sources/quality made a huge difference in how much bass was being played, and was typically set wayyyyy too low. So I gave up on using a test tone and just started playing my hardest hitting songs and made adjustments this way by listening to the sub. I also still used the voltmeter on the amp's output while speaker was connected to see what the voltage spikes were and made sure they weren't exceeding what the sub should be seeing.

Coming from touring sedan owner, tap into the front left and right speakers for the LC2i, keep the threshold on max and play around with the accubass and bass gain knob up top to your liking. I installed the knob for the LC2i to control the bass to my liking depending on the song. When tapping into the front speakers the bass roll off is almost none existent since that applies more to the sub output, that's why you can keep threshold all the way up.

I don't know if the Touring Sedan is much different than the HB Touring in terms of speakers, but ya, I'm tapped into the sub channel. I don't really know if there's actually any roll off or maybe very little. Either way I don't really notice it, and so even if it's there it's ok for me. Especially since as you said, I do have a Bass Control Knob, mind you mine is on the AMP not the LC2i. But ya, I manually adjust the level all the time. As I said, I noticed the amount and loudness of bass is so incredibly different from song to song and even from source to source to the point that, at least for me, roll off is the last of my concerns. I'm having to adjust the bass on the fly mostly for the fact that it changes even without volume changes.
But thanks for the suggestion, this should help those that have issues with roll off.

forsure man, i had it tapped in to the sub output and yeah it was okay bass, but you really see the difference when tapping into both full range channels up front, then you can adjust the crossover at the amp to only play tones under 80hz. As you have it now the frequency range you're playing is very minimal, you're missing out on alot of the "Midrange" bass most songs have thats why it doesnt sound balanced with all songs :)

Hmmm, that's a very interesting point about songs with midrange bass. That would explain why there's such huge differences between songs. But doesn't that mean that the stock sub was also not playing a lot of the midrange bass either? I figured the stock sub signal should cover exactly the bass range that you would want in a system with a sub.

I guess it may vary a bit since your sub was in an enclosure compared to free air in my sedan, but the tuning done by the amp regardless sends very little signal to it whatsoever that’s why the bass is so heavy in the front doors, they receive full range signal and can play down to subwoofer level tones because of that fact. Tapping into that signal and crossing over at your aftermarket amp is night and day, if you want even better sound quality from the stock amp (mids and highs) I suggest replacing tweeters up front with maybe the Polk db1001, they are direct replacement and do not need the crossovers included with them since the crossing-over is done on the stock amp. With those two things (tweets and proper signal source) I guarantee you won’t be disappointed ;)
