2016+ Honda Civic Type R Subwoofer Amplifier Installation 

This is, without a doubt, the best overview I've found on the best way to install an aftermarket sub, LOC, remote, and amp in a 10th gen civic hatchback. I finally have some semblance of knowing what I need and how I might do the job in my own setup. I also really appreciate that you didn't just explain what you're doing, but WHY you're doing it THAT way. Thank you so much for this very thorough and high quality breakdown!

I've literally watched this video 50+ times. I watched it piece by piece as I did my own install. Very helpful. Thank you very much sir, I would not known what to do without your help

Awesome Video!!! Very clean and professionally done. Unfortunately I had my system installed by a professional because I found this video afterwards. But I enjoyed watching it. It was very clear and step by step DIY and it was informative. Thank you for the time and effort you put in to make this happen.

You delivered your promise... Kudos to you. Will definitely make this my blueprint installation. Very well done. 👏🏼👏🏼👏🏼

Super clean install! Taking the time to wrap and secure all the cables is a great way to keep it neat/tidy. I liked the way you incorporated the bass boost nob into the existing pop-out panel on the far left lower side. Perfect spot to blend it into the lower dash. Great hack to make it fit into a tight spot too. I’m applying this to my 2017 Accord! Well done, sir!👍🏼👏🏼👏🏼

Great tips. I've been wiring amplifiers in all of my vehicles for many years, and still took away some great info that not only helped with this install, but for many more to come. Thanks

Thanks for carefully showing us how to install this so clean and neatly. It definitely demonstrated that I need some patience when doing this. Also, it kinda scared me into not wanting to really do it, but I wouldn't trust anyone to do it as careful and extensive as you have.

Thank you. I followed this video along with another RU-vidr and finally got my amp and subs installed today, it took me 5 hrs.

I personally don't have a civic, but I was looking for a quality explanation on the LC2i and this video was of tremendous help to me. Thanks for the high quality content. Liked, and Subbed.

One of the best videos I've seen so far on youtube for sub/amp installation using a LC2i. Very well explained and professional. I'm preparing to do an install on my 2013 accord EX-L and this will help me a lot. Thanks so much !

Nice job. Its good to see someone actually take the time to do a clean install and give a amazing step by step on how to do it! Hats off to you sir!

Thank you very much for the thorough breakdown and run through of putting in your system. I can’t wait to get my subs and amp in since I already have my LC2i here by its lonesome. All internals we’re already upgraded in my 20 Accord Sport as well. Cheers!

I was able to fit the PCB from the ACR-1 into the switch blank vertically with a dremmel and a few attachments. Came out super clean... never would've even thought of it if it weren't for you. Thanks man!

Thanks for all the hook up information.Today I will get an inline fuse for my new LC2i.I almost forgot about that.I got a 50 fuse for my amp.

Outstanding video. Detailed and quite comprehensive. I'm doing a similar install on a Ram 1500 and you gave me the idea of using the double-sided tape to help mount the LC2i and the amplifier. Thanks!

Excellent video, thank you for posting and i love the clean setup...

Great install! I’m really thinking of doing my own install on my 17 civic

I set up the same amp and LC2i in my F-150. I’m pushing two punch p3 10’s and it is amazing. I like that you set the gain on the amp to zero. I will have to play with that. I am still tuning mine. Great video.

This is the best install video i have ever seen... i watched this for the ACR-1 and LC2i install portion but fount all of it very useful. I drive an Accord and it pretty much all applies.

Excellent clean and safe install, very well done video... thank you

Plan on doing the same to my sport. Very easy to follow along tutorial. I really appreciate the diagram you drew up.

Holy crap you're going to save me a ton of work thanks!

Thanks for making this video. Great video 👍👍

This is a very great video. Thank you so much for taking the time to make this.

Man... your setup looks if it factory OEM setup, so professional. Best video...

Yooo, thanks so much for this vid, man. Was looking specifically for a clean way to connect power to battery and BOOM! Props. I can’t wait to be boomin’!

Wow best amp install ever. Super clean and very detailed

I'm gonna learn a lot from these walkthroughs you do cos mine is gonna spend plenty of time being worked on when I get it 🙂.

Hats off to you, best walk through I have seen in a long time. Sub and liked!

Nice 👌🏼 very professional installation thank you for explaining everything everything so detailed 👍🏼👍🏼👍🏼

That Crx si tho 🔥👍🏼👍🏼 good video btw! Subscribed bro

I'm impressed. Clean install and and precision tutorial.

great vid! exactly the info i was looking for.. if i make one recommendation.. I'd probably use Tessa tape to wrap the plastic loom in, would add a nice layer that would prevent wire rattle and in warmer climates hold up better (coming from texas here). again great vid!

loved ur work bro... its super neat and clean.... keep it up

Really nicely done...clean and safe!

Nice clean install for a diy project 👍

Great video! Literally doing this on my 24 Pilot Elite!

Not sure if you are an expert but man you taught like a teacher. Very nice

Well done, boyou. You did it much cleaner than I did.

The Bic pen 🖋 trick saved me so much time great idear thanks for this aw install video my sy looks better than a professional job

Good videos man very detailed. Thumbs up

Great idea to use the grommet for the hood release, however, right above it is a capped half inch hole that you can use for up to a 0 gauge power wire. Pull away the insulation padding about a half inch above the hood release grommet and you will see it.

Incredible walkthrough... thank you

Hey just a tip, if you don’t want your power wire to run behind the front fender, you can find another grommet behind the battery that leads behind the clutch pedal. Nice video!

Badass!! I also have a type r. Looking to do some of your mods. Subscribed

Great job! Perfect explanation and easy to follow! Big thumbs up. I subscribed to your channel. Look forward to more videos. 👍

Very clean install

Fantastic video!!!

I liked this video. Well done, and thank you.

Great vid man👌🏼

Good Job !

Also a note, if you are using 4gauge or larger wire it won't fit through the grommet with the hood release cable. Luckily, directly above the hood release cable like roughly 1" above there is plastic plug you can remove that provides another hole to route your power wire through. Just need a grommet or to drill out the plastic plug you remove from the hole.

I plan to do this tooo!!! but not yet not yet!!! Great video btw

You did it! Thanks for sharing! ❤️

Well done trying this on my 07 e350. Good thing my battery is in the trunk

Very nice!

Definitely not a bad install but I noticed a few things that should be done differently. 1) Power wires should realistically be run through the firewall and bundled with other wiring harnesses versus run through the fenderwell grommets which can allow moisture into the vehicle as the fender is not sealed off from rain in the same way the firewall is, considering the hood and cowl both have seals to prevent water ingress in the engine bay. 2) Power wires should be attached directly to the positive battery terminal. As it stands, you are powering the LC2i and that Rockford off the factory 8 or 10 gauge wiring from the battery to the fuse box, and it's not designed to handle the extra 15-20A nominal power you might be pulling on normal use. Connecting directly to the battery eliminates the possibility of stressing the stock power wire and it also eliminates the possibility of confusing the car's Electronic Load Detection and causing a fault. 3) While your LC2i is definitely a nice piece and has bass rolloff capabilities, your Rockford amp has the ability to accept speaker-level inputs and do its own signal step down, thereby almost completely eliminating the need for the LC2i. The LC2i can definitely be used as a signal clean-up and re-level if that's what you're looking for, but it was not entirely necessary and omitting it may have saved some time and effort, not to mention cost. Overall quite good, everything should work beautifully. and considering the significantly higher quality of the components used versus stock, it probably sounds pretty good too.

helped with my remote thanks! I wish I would have ran through that outside gusset instead of the inside the engine bay one

Great job.....but I don't have the type R...any suggestions on where I can tap power from speakers on my SI coupe

that looks like a tough job! appreciate your video editing and sharing this with others!

First off awesome videos and very clean install. Two questions I have for you is 1) Do you hear or notice any rattling noises considering that you mounted the sub into a factory, plastic enclosure? I’ve always used MDF sub enclosures but I was considering this option to save space in the trunk and not have a box. And 2) Does the bass from the sub sound evenly throughout the car even though the sub is mounted on the right side of the car?

I recommend changing that gain control out, for an RCA level input knob. I personally run SPL cartel, because they're linear voltage, but you don't want gain control, because they're more prone to causing equipment damage. Also, move that power lead, to a better spot, you're going to cut through the shielding, opening and closing your hood.

Wish I could use the same mounting location for the amp in my Sport Touring, but we have a spare tire instead. Only thing holding me back is not being able to conceal the amp as I don’t want it to be visible, or interfere with the cargo area. Maybe I’ll take the spare out!? Nevertheless, I appreciate the in depth guide! It’ll be the blueprint for my upgrade!

Thanks for the video! Could you please provide a link or description for the white plastic power wire holder you installed to hold the power wire under the hood near the hood latch cable?

Hey nice install , how did you tune the sub? I have a similar setup and im wondering how you tuned yours

Nice setup, very good information, I just hooked mine up today and I did not know that you need a fuse holder from the power cable to the amp. Can you tell me where you got the fuse holder and are the wiring 12 gauge? I used some 12 gauge sting ofc wire for my power and ground to my tap from the amp. I don’t want any fires in my car. Will an inline fuse work from the auto parts store. Let me know where you got yours. I used ofc wire for all my wireing and the 12 guage worked great for the lc2i, I know that is overkill, lol.i have to use the best wires.

Wow really nice video with great visual and speaking voice. Do you have a link to the amp you bought or have the suggestions on an updated model?

Very detailed vid man! Just waiting on my stuffs. Question, what size did you use for the foam tape? And what do you call that clip zip for the wire going through the fender? Thanks in advance!

Thanks 👍

Amazing Video Very Detailed But Quick Question... I Love How The Amp & LC2i is Hidden Under The Trunk Lid This Wouldn’t Cause Them To Overheat? I Just Ask This Since There’s No Airway There I Suppose...

Hey great informative install I'm doing mostly the same ...but I just wanted to know what kind of window visors ur using ...I wanted weather tech but it's not avail for the type r..

Nice video

Thank you so much for making this! I plan on attempting it with the same sub. I was wondering if you’ve had any issues with the sub bouncing on the factory grill at higher volumes? I read somewhere on a forum of someone having that issue with the Rockford setup.

Great video, so I'm wondering if you only hook up one set of speaker wires to your LOC (looks like you did the left channel), does the signal come out of both RCA's to go to the amp? I'm going to tap into my sub on my 2019 civic SI with a LCi1, to add 2 10s and have a mono amp, but not sure if you need both RCA's? Or to hook up both channels to LOC to get both RCA's to output to the amp?

Great walk though, thank you! Quick question of ya'll don't mind. Since the line converter accepts 2 qty sets of high level inputs and the sub factory only has 1 qty set of high level, do you just run it to either the left or right or twist the 2 positive together & the 2 negative together?

Tremendous job! Would you recommend a different audio control than the ACR1 since that looked a little tough to get it to fit?

Another great DIY! Any plans on upgrading front door speaker and front tweeters?

Perfect explanation of installing, but ive got a question... With audiocontrol unit, there was not presented alternator noises?

do i need an lci2? i just got a new car and i took out my old sub and amp but they never installed an lci2, should i get one for my new installation? what exactly does it help with/do?

Final question, thank you for answering the other questions, where did you put the ground for the lc2i, did you use the same bolt or the black cable, and where did you get the power cable from the lc2i to the amp

You think 8” kicker comp R will fit? Please post a video of the sound of your set up. Thanks and good tutorial btw.

Nice looking install. I have used the LC2i before, but not the remote knob. Does it just lower the gain through the LC2i, or does it actually control some sort of boost? Also, I assume because you tapped the wires that were going into the factory sub, that the signal you sent to the LC2i was actually coming from the factory subwoofer amp. Thanks!

Great video 👍. if you found some nice beats for your time lapse shots be nice to put it. To each there own tho

Thank you ! Is it the same for the Honda Accord 2017? Of anybody know please leave the link!

Great installing and very nice video! I'm planning to install a sub on my 2017 CRV LX and it doesn't have a sub the back like your Civic. Do I have to remove the head unit to wire my amp (the signal wires)? If yes could you explain a little about how to do that please? Thank you so much!

thanks so much!

Do you need to upgrade your battery or a capacitor to cater for the increase of power drawing from the amp and sub?

Great video very good details! Keep it up. Just some questions...So no need to get remote in for lc21 as it turns with speaker signal? Can you also provide what cables you used for each connection sorry my first install with and lc2i. TIA

How can I hook this up to a 4 channel amp for my mids & a regular 1 channel amp on my subs? I have a Lc2i

Amazing video! Do you know the size of the wire that connects the amp to the stock sup? Is it 16 gauge?

Question do I have to run the RCA cable from the aftermarket radio to the back of the trunk..or just the power cable?

Nice video. How you ran your power cable from under the hood, does it not get pinched when the hood is closed?

not sure if you have answered this question but, ive been looking at the thread from CTRMofo for a while and am still debating if i want to change all the speakers and subs since i want to keep the car relatively oem. what are your thoughts on each part of the set up ? meaning.. do you think it will be a significant upgrade if i just install an amp, or should i go and change all the speakers around the car as well. the question is derived from a cost saving saving standpoint but rather i want to eliminate changing out oem parts as much as possible. the oem sound system is rather lacking. thanks !

Awesome video my dude! I got a 19' Type R, but I haven't messed with the subwoofer yet... is that stock box the sub is in just cheap plastic? I can't imagine the sound being too good out of a plastic box o_O

Hey man, great video. I know I'm late to the party but I'm finally going to pull the trigger on my 2017 Type R with this build. I wanted to ask two things: how's it holding up and problems with it after a few years? And how come your didn't use a distribution block instead of the 1 amp inline daisy you did? When I used to do stereos in college we used distribution blocks regularly and I used them for my ground and power for my comp cars all the time? I am not familiar with the LC2i so I am not sure if it was because of that? Thanks man, hope to hear back from you in a few days because I should be installing this in the next week. Happy new year!

Very cool. I understand this all. But what i must do with radio? Also for chinch signal ( radio/amplifier) 😊 pls help. I dont understand how to get the radio removed 🙈

quick question... for the lc2i, did you plug into the left or right speaker input? or both? im planning on tapping into my sub just as you did but wasnt sure where to plug it in. AWESOME videos btw

Great video. 👍im a 16 year honda master tech. Clean install. Got links to the complete units. Amp and lc2i? Wanna copy this set up.

Do you think you would be able to fit 0 gauge wire? I just sold my A8L and I kept the sub. I had the sub getting 2000 watts rms and the battery was located in the trunk so it was an easy install. Now I'm not sure I can send that much power if I cannot get the 0 gauge wire to properly be installed and unseen. Any help is appreciated. I have a 2021 type r

Awesome video! Did you aftermarket install your sunroof? Looks great
