Thank you @ctrmofo for this thread. I honestly thought my brand new ST hatch had a defective HU when I picked it up from the dealer. How is that even called a "premium" sound system? Started looking at custom boxes, similar to what I had in my 8th gen sedan, Audio Integrations. Not much out there. This thread, and a YT video from piercedasian restored my faith in humanity.

The Pioneer sub is now installed, driven by Alpine MRV-M500, which I salvaged from my 8th gen Civic. Finally the audio has some soul in it, although response could be a bit more crisp (another sub maybe). Will tackle the door speakers and the center channel next year. Happy to be hearing notes below 80Hz in the meantime. BTW... is there an ideal HU SUBW level to maintain? I have the remote knob on the Alpine amp to tweak gain as needed, and bass EQ on the amp itself. What is the HU LP frequency?

Would be interested in that modified cover you created, but I get that it was a limited run. Thanks again for all the info on here!!

HEADS UP! do NOT use the oem sub signal (the white harness, single channel +/-) that feeds the oem sub box. we have discovered several things:

- that signal is only good for 5hz-45hz. you need a full range signal and feed the lc2i to do its job.
- it's time phased, meaning there's a delay vs the front door speakers. will get annoying as you turn up the volume.

we have tested and reconfigured the wiring and totally changed/improved the bass now with our lc2i, jl amp, and jl sub in the oem box to a whole new level. see the complete and detailed install and tips in the fb post i've made last night.

results:

- no more delay of sub bass.
- broader, richer, fuller bass frequencies - allowing lc2i to clean up and amp to then roll off at your set low pass filter.
- simply amazing bass!

I finally got around to rewiring this over the weekend. It definitely makes a difference. The sound seems more natural, less boomy, bass is more fully integrated with the music. Not easy to describe, but very glad I made the change. I don't listen super loud, typically volume is set between 12-18, but that's plenty loud enough for me with this setup (RF amp, LC2i, Alpine Type R sub, JL front door and center dash speakers).

Well, well... shoulda kept my head up and read the thread fully. The boomy, droning/delayed bass is what I've been trying to tune out of the system for some days now. Easy enough fix, but man... what an awkward audio system in this car. Thanks.

I'm such a dork. Got an 8" MB Quart shallow, DVC 4-ohm sub coming. $50 after discount from Walmart. Will be interesting to A/B against stock, with stock power at 2 ohm.
Hi Todd:

Did you ended up doing this MB quart install? If so, how you like it?

I've been reading through the thread and it seems everyone really like the JL audio, alphine, kicker, pioneer and rockford.

The stock subwoofer on the Type R is trash especially for a car that is really quiet from the factory Honda could of did a better job... I understand the car main purpose is to be a track car and when driving fast and hitting corners thinking about music goes out the window but you can't always drive fast on the street. *I wish* My 8thgen Si stock premium subwoofer has more bass and tremble than the Type R Sub which is crazy. Plus the Type R cost way more than the 8thgen Si..

What would be the best overall upgraded Subwoofer without an amp???

Don't have to be earth shattering the windows, the neighbors hear me coming and people feel the bass in their chest outside the car. *Probably change my mind in the future*

It is not the sub's fault in reality, the stock amp sends a very light signal to the sub. The sub could potentially be capable of much louder and fuller sound, but it won't happen with the stock eq coming from the amp. I wouldn't bother upgrading the sub only, it is only worth upgrading if you also add an amp, sub and LC2i.

I am new to audio,
looking to upgrade the speaker and sub in the car. I am not picky nor do I know about sound quality. I just want better clarity, what should I do?
I bought jl audio c2-350x for the centre dash already.. and also Apline SPR-10TW for front tweeters already
looking for advice on rear tweeters and door speakers.. is there any drop in replace for the sub in the trunk. I dont want to lose my trunk space..
thank you

If clarity is what you are looking for, some JL C2 650 speakers go great in the doors along with some dynamat. They are 4ohm which match the stock impedance and will sound very nice. As for the sub, there are some shallow mount subs that you could drop in but they will not sound very good unless you actually put an amp to them. You will barely notice the difference when you raise the volume without an amp and LC2i.

Has anyone experience upgrading the sub with no amp that you know?

i will look into JL C2 650 definitely, most likely wait for valentine sale and buy it. for Amp, which one should I get? I dont have a clue.
and do I need to buy LC2i seperately? or is it something that integrate in an AMP?

is JBL club 6500c any good? it comes with two tweeters as well.

The write up on Facebook described it as about 25% more bass, I think that is a generous estimate though. I installed a bigger sub and amp tapping into the sub output from the stock amp for signal and the bass was disappointing. Adding the LC7i allowed me to add some bass back into the signal the stock amp puts out giving me the best results. You'd be better off running the hondahack and using Viper4Android to give your stock headunit more bass over upgrading the sub without an amp to power it.

Those appear to be 3ohm speakers, I am sure they will sound great and potentially be louder than the stock speakers because of the lower impedance. Just make sure you add some dynamat to the speaker mounts to at least cut some resonance and get better sound. At higher volumes there might be slight distortion because of them being 3ohm but you might not even play them that loud so it likely won't be an issue. I would just buy the LC2i separately, it is not too expensive. I believe some of the more spendy amps can clean up the signal like an LC2i but you will usually pay more money. You can't fit a super big sub in the stock enclosure even with a spacer though, so I don't think you need too much power. I went with the Kicker CompR 8 inch and a spacer I got from Amazon to mount it, my amp is really powerful but I have it turned down because it is way too much power for that little sub. I also went with the JL audio C2 650 components and running them off a small Kicker Key amp under the seat for the front speakers.

thanks.
i didnt know the sub can light up. again, I am completely new to audio. can it be red?
should I bother to change the trunk sub if I dont get an amp?

could yo suggest me a simple set up.. for all speakers front and rear, also trunk sub with amp & LC2i..
I already bought JL C2 350x and a pair of Apline tweeters.. I dont know what I am doing and buying to be honest.
