- the LC2i is a 2 channel line out converter with accubass™ and subwoofer control
The LC2i, is a compact, two-channel processor with active input circuitry, which allows it to accept speaker-level signals of up to 400 watts per channel from factory-installed source units or amplifiers. It converts them to high-quality pre-amp signals that can then be directed to after-market processors and/or amplifiers. Users can enjoy maximum sound quality while maintaining the use of factory volume and steering wheel controls.

You guys just saved me hours of headache trying to get this to work better. I totally forgot to adjust the threshold and was getting pissed my DSP was sounding like crap when it wasn't even getting a good signal to begin with.
To this day this is the best explanation of this devices function on UA-cam.
Great video ! Answered a couple questions I had
Awesome video!!! Thank you, I was wondering how to tune this thing!! Wil be watching this video again once the weather clears up!!!
Thanks, glad we could help.
Great video and informative about what the threshold does on the accubass but you gotta make sure maximized isn't blinking because that means you're clipping
Always love your guys' content. My trusted local installer suggested the LC2i when I wanted to add a subwoofer + amp to my 2014 Mercedes E350, instead of a cheap LOC. He tapped into the premium Harman Kardon subwoofer to the LC2i, giving signal to an old Alpine mono amp powering an old Alpine 12" in a sealed box. Long story short, it sounded awesome. I was most impressed of how this setup played ultra-low bass notes.
Currently, I transplanted the LC2i, alpine sub & amp to a 2019 Rav4, non-JBL system. The same installer tapped the front speakers to the LC2i. For the most part, the bass hits very hard. The downside is, it doesn't play the same ultra-low bass from the same tracks compared to when the system was in the Mercedes. I'm wondering why this is the case? My Rav4 has the OEM stereo/speakers, so there is no factory amp, and I doubt the OEM speakers have passive crossovers or bass-blockers. I also add that the OEM radio does not decrease bass signal as the volume is turned up, which is what AccuBass is for. I suspect that the OEM radio was designed to cut down ultra-low frequencies at all volumes to save the OEM speakers. What are your guys' thoughts?
This is very informative.
Von Jose thank you
Yes ! now I can remove my amps built in high to low to this !thank you
thanks for the info as im picking one up and your tutorial is very detailed.
Thank you, enjoy
@@FiveStarCarStereoInc I like that 500 RWS @ 4 ohm amplifier that has this built into it more. It's a monoblock though.
Fernando what such a huge help.
It's a good thing you had Pedro for all that help
Nice Napoleon Dynamite reference
thanks guys!
Acubass is amazing. Lc7i Makes mids, highs and subs play clean.
I didn't think the lc7i had accubass? I'll have to reconsider, if so.
Thanks Dean once again
You guys are fantastic. I'm reviving my old system from high school and putting it into one of my daily drivers after years & years. 02 Chrysler 300M. JL12W7, JL 500/1 &...stock deck...yes I know. But its the RB1 NAV & its gorgeous. Anyways. I have the LC2i & the M's have 12 speakers in 9 locations or w/e it is wonderful Infinity system with a ~366watt OEM amp. *My Question is* can I splice into the wires on the OEM amp's wiring harness to run my LC2i? I'd sort this out myself but I realized at 1AM I had broke my big inline fuseblock for the power wire many years ago removing the system from the original 300M. -_- lol so its a "tomorrow thing".
Cool video guys
Thank you, we try.
Love video
Thank you!!!
very informative.
Thank you.
I am having problems with car audio system installation. I have a 2015 Dodge Journey R/T. It has a stock Premium Alpine Audio System. 6 speakers 1 subwoofer. I have an AudioControl LC2i LOC tapped into the stock subwoofer. I have the GTO in the bypass position, as I am using a toggle switch to turn everything on and off manually. Tuning the LC2i is fairly straightforward. Your UA-cam videos helped with that. My issue is with tuning my amplifier and subwoofers. I have an Alpine MRV-M1200 Monoblock Amplifier powering 2 Alpine DVC 2 ohm + 2 ohm SWS12D2 Subwoofers (trying to power anyway) wired in series parallel to 2 ohm final impedance. Correct me if I'm wrong on the wiring terminology. The RCA wiring is driving me crazy. When hooking them up I barley get any bass. Even after adjusting the Gain and Bass EQ. When only one RCA is hooked up I get better sound. Do I need both RCA's hooked up. I also noticed in your video you only had the one RCA hooked up when demonstrating the tuning process. I also don't know anything about the Low Pass Filter or where it should be set at. Thanks for your time
hey where's is the stock sub in the 2015 Dodge journey rt.
1-If you only connected to one side of the input of the LC2i only one side out will work, Use a y connector out to your amp. I have found in most cases the thresh hold was off or turned all the way left counter clock wise. The Thresh hold was intended as a place for the accubass to start. I turned it all the way Right so its always on and adjust bass on top and accubass to my taste. I used my amplifier out from my stock sub woofer to the LC2i also, I connect the HL to the left side and used wire jumpers to the right side.to feed both RCA out. I just thought it looked better.
Under the front passenger seat
2016 outback and I'm about to add a amp and sub to its Harmon Kardon system. Thanks for the info, sounds like I need to spend another 100$ over the 10$ passive LOC I was looking at... at least it gives me the ability to add regular speaker outputs. The🤣
That's good to know doing a rebuild in my car wanted to see if I should wait on the new DM 810 or get the dqdx
I'm really looking forward to this and the new Phoenix Gold
Very helpful! One question does the sound quality make a difference if I tap the signal from the factory sub oppose to the front door speakers?
I installed a JBL BassPro SL2 powered subwoofer on my 2016 Volkswagen e-Golf (non Fender audio) by tapping the front speaker outputs and connecting them directly to the sub’s high level input.
I noticed the head unit output now clips at a much lower volume and it gets unusually hot. It is impossible to set the sub amp gain as the levels are all over the place and slight changes to the amp gain cause the sub to cut in and out.
I verified the polarity of all connections on both ends and everything seems alright. I would assume tapping into the speaker outputs effectively lowers the impedance seen by the head unit onboard amp causing it to go crazy.
Wondering if using an LC2i instead of the sub’s high level inputs would make any difference.
Nice video, as always. Question, can the LC2i be used with the Kicker Key 200.4 and a CX600.1? While still utilizing all of the Key tuning features? TIA
I have a Pioneer AVH200BT with *optional pre outs for Sub, as well as front and rear..(*with normal speaker output wires as well) i just put all new door speakers as well as a 12" sub. Would you recommend using my pre outs or a line converter so it can be "fine tuned"??
Thanks in advance

Question for you guys.. I have a vehicle that had a Factory subwoofer, I have since added a component sub with a 300 watt amp and I have an LC2i which is getting the input signal from the Factory Subwoofer Wire/output. Now i have the accubase threshold turned all the way up and if i keep the Accubase knob and the Bass knob both at the 12 o clock position as a starting point this sub is banging like crazy I have to turn the gain on the amp barely up?? Is this correct or should I lower the Bass knob completely and turn the amp gain up?? I havent been able to find a good starting point for the LC2i when its getting an actual factory sub signal as opposed to it usually a full range signal.
My LC2i stopped putting out sound.Tested inputs from stock subwoofer and it's putting out 8.6v but no output reading from LC2i's RCA's........does it sound like a bad unit?
What frequency signals do you get out of the MAIN outputs? What frequency is the BASS output playing, I see it run 33 - 10k total, but I want to know if there is any separation
do i need to disconnect the lc2i from my after market amplifier before applying one of the option? I'm leaning towards the option 2 as i can't determine if I am losing base when I turn the volume up. i have 2016 accord touring. please let me know. thanks.
So in a 2018 Terrain with non-Bose I want to use a PAC LP7-4. I am adding a 4 channel amp for doors and a mono amp for subwoofer.I plan on sending the 4 factory high level signals into the PAC for the 4 channel amp and then just using the RCA output plugs on that amp to feed the mono amp.Will the mono amp be starved for low frequency because of the factory bass rolloff? Is the LP7-4 a bad choice for what I want to do?
your better option would be the Audio Control DQ-61
.Key Features
:
Signal Delay:
Because of speaker placement limitations and the seating positions in a car, it is almost always the case that the driver of the vehicle is in an incorrect acoustic alignment. This exists because the driver is close to the left side speakers and further away from the right side speakers. Thus, the sound from the left side arrives much sooner than the right side. By delaying the appropriate speakers for just a few milliseconds, the DQ-61 is able to allow the signal to arrive at the same time putting the driver in perfect acoustical alignment.
AccuBASS:
To protect OEM speakers, car manufactures often limit the bass frequencies at higher volumes. AudioControl has developed a patent pending circuit called AccuBASS circuit to compensate for this factory roll-off. The AccuBASS circuit automatically engages at a preset volume level and reverses the factory bass roll-off to give you the music the way the artist intended it to be heard.
Speaker Level Inputs with Selectable Summing:
The DQ-61 is equipped with six high-impedance speaker level inputs that allow it to accept amplified signals from any factory installed amplifier, even Bose. Unlike an inexpensive passive line output converter, the DQ-61 offers the highest possible sound quality and performance
.
Equalization for Maximum Control and Performance:
Like all of AudioControl's high performance signal processors, the DQ-61 is designed to offer maximum audio performance and control. All six output channels are equipped with highly accurate graphic equalization filters. This equalization allows for the taming of the most demanding car acoustical challenges or correction of factory radio response curves.
Is the bass output of the LC2i full range or does it have a low pass filter on it? I noticed the higher frequencies on the RTA taper off when you switched it from the main to the bass output on the LC2i.
I have this connected into a epic center then the epic center into an mono d amp my question what should I adjust on the Lc2i the bass knob or the AccuBASS I am also using a dd1 plus so but it doesn’t distort the yellow light comes on before distortion
im running 4 amps, 1 for bass, 1 for mids, 1 for mids & highs and 1 for mid bass, would you recommend AudioControl LC6i in order to separate the bass from the rest of the system? pls help.
Need advice, so I recently had 2 10’s installed, a bass amp, lc2i, and an extra battery to my 16 challenger 8.4 inch factory radio. The issue I’m having is that my two front door speakers seem to only have bass coming out of them, while the dash and rear speakers I can hear more clearly. Did the installer do something wrong? Because I want to hear sound other than bass coming from my two front door speakers. Please help with advice.
When adjusting bass for sub in video you switch phonic to sub outputs. What happens to the mid outputs? Are those being adjusted as well. Is there a switch to adjust each outputs separately? I don’t want to have a sub, subbing and my mids distorted. Thanks in advance
Can the lc2i show when the head unit is clipping or does that need a different device to test with?
Bear with me here. I have an Acura RSX (Bose system) with an aftermarket Kenwood head unit that has a 5V pre-out. I’m replacing the old amplified, self-contained Bose spare tire subwoofer and replacing it with a new amplified, self-contained JBL BassPro Hub. I’m keeping the front factory Bose amp.
If I’m thinking about this correctly, the front factory amp just carries a remote turn on and speaker level outputs to the sub (it doesn’t amplify the sub), so is it even worth it to use the lc2i from the front factory amp to the new JBL sub, or should I just bypass the speaker level outputs from the factory amp, and instead use rca cables from the 5v pre-out in the Kenwood head unit to the JBL sub?
I’m not sure, but I don’t think it matters if I bypass the factory amp (and ditch the lc2i), because the subwoofer isn’t amplified from there anyway. Am I correct in thinking this way, or in my case, is there still a benefit in using the lc2i?
These guys party soo hard
I was wondering if this increases voltage once you have already set your amplifiers voltage. Would you have to readjust the amp voltage to the increase in acu bass?
I have a 2013 dodge avenger with boron acustics 6 speaker system..I tapped into my 2 rear 3 way speakers to lc2i pro to run 2 10s. It sounds muddy..should I tap into the two front door speakers wich are woofers?
Can you use a subwoofer amp on each output? Both main and bass if you tapped into the rear deck speakers. My amp is NOT strappable.
Great videos as always. Question? I have a 2015 Mercedes C class w/Burmester system. I tapped from the subwoofer outs to the LC2. During the setup, I turn everything down on the lc2, can't get it to light the maximize(or clip) when the volume is increased. Any reason for that?
Did you figure this out why it didn't clip? My guess is you reached the lc2i max signal. This is good news tho, you can now go full tilt on volume, just adjust your amps down a bit. Acu bass you turn right under half and turn screw on side down. Then turn radio up.....way up like 85% turn bass knob to like 25%, now turn little screw real slow. This os when the magic happen. Your little clip light. If you turn this little screw too far you can send a too strong signal to amp. Amps has voltage input limit. Look that up and don't go past that.
Hey guys thanks for the great vid as always! I have a 2017 Wrangler with the factory Alpine subwoofer in the trunk floor. I want to add an aftermarket sub and amp. Do I connect the factory subwoofer’s speaker wires to the LC2i’s input?
Yes that or get the PAC Audio Amp-Pro for a true Pre-Amp output
Five Star Car Stereo do I need to have speaker wires to the lc2i from 2 different speakers and can it be any speakers
Very good video currently just running a pac lp7 going to a sk2500 running a zvx12 wanting to run my fsx 6.5s an tx 6.5 door speakers on amp my guess is this should do the trick to being able to run my sub amp an speakers amp an would a line driver help any
My guess would be with the accu bass I wouldn't need a line driver
la restauracion del bajo es al nivel de un epicenter ?
I just recently installed a lc2 into 2015 gmc sierra it has the bose i spliced into the rears instead of the sub is that okay still? Also when I disconnect one it rca sounds louder and when j connect the 2 it drops what can it be?
Another excellent video Five Star Car Stereo! On the LC2i, do the Sub outputs put out a full frequency or just the lower sub frequencies? I'm trying to figure out if I can use the LC2i or if I have to get the LC7i. I currently have a 4 channel LOC that the rear channels pass through my sub amp to the rear channels on my 4 channel amp. Also, will AccuBASS restore the bass frequencies that my stock head unit seems to filter out around 35hz and lower at all volume levels?
+FACTION95 the bass channel is only for bass. It will only fix bass roll off as the volume goes up. It is not an EQ so it can not fix the DE-EQ problems of the factory radio. For that we use the LCQ-1
Thank you so much! You guys rock! When are you going to open a store in Southern California?
+FACTION95 haha, it is a nice place
I have a lc6i and when i turn car off the speakers make a pop noise and i read on manual that to use the remote out option but i dont know if they didnt use a remote since it has GTObut if it doesnt how should i get a remote signal from my 4 channel amp and plug it in to remote out? Sorry im trying to figure it out before taking it to install place and thats an hour drive so i rather do it myself. Any help id appreciate it
What if you turn AccuBass all the way off
I have an epicenter from audio control. Would adding this still make a difference on my stock stereo system?
Thanks for this video guys. Between the LC2i and LC7i which would suit me better? Stock Wrangler headunit, 4 PolkDBs, Stealthbox JL Sub, everything to a AlpinePDX amp.....THX!!!
If it is the basic factory stereo the lc2i will work unless you want fader. If it is the premium factory stereo you will need the lc7i for the summing capabilities.
Great Video, Thanks Guys! Converse said like 2 dozen words tho....... Any experience this working with a Bmw 2012 7 Series? The remote signal is at such a low voltage, unsure the Lc2i will work with after market amp.
Hi what is the max current draw from the remote out, the manual says it can only turn on 2 amps but i have 4 so will relay it, but need to know if this will even turn a relay on.
whats better to use? Pac gm 61 harness or the lc2i pro? are they essentially the same thing? my volume goes up to 63 (max) without any distortion. i dont want to cut into speaker wires if i dont have to..... but i want that RUMBLE. my last vehicle didnt have a good LOC so it was lacking on some notes. which one is better to use?
Hey love the video . But can you guys put a rag on that glass ..
Great information, I had a question you stated that when using 40hz tone to set bass level the maximize light should not turn on. But it's ok for it to come on and off when playing music. Is that correct ? Just wanted to make sure
When the light comes on means there is distortion. For certain subs they have tolerance for such. I have kicker comp c and tuned my gain to where the light comes on every 2-3 seconds. Mostly when there's a kick in the beat. The thing with distortion is that it's a form of DC current while speakers take AC. The voice coil in the subs is supposed to go back and forth. Too much distortion and it gets stuck in one position or the other which heats up the voice coil and detaches it from the speaker which is known as a blown speaker. So the point is that the light is distortion, but don't be worried just figure out if your subs is a quality brand that can take it. The light coming on every second or 2 second isn't anything that can damage it as it's not receiving DC current fully. Now if the light was on solid then that's something to worry about.
So I’m confused about all this audio stuff, do I need this if I have a DSP and crossover? And how will this make a huge difference?
I have a question. I know this has a control knob but my amp has one too. Do I have to install both or how does that work? Thanks
I have this lc2i for my 2 Rockford fosgate 12s what do I need to do to wear I don’t get Distortion?
I really your video. very very very informative.
I have questions, I have tapped from the subwoofer (factory stock sub) and there are 2 wires. where do i connect the 2 wires? The LC2i has 4 wire input,. L+- and R+-. Do i bridge it? how about the RCA? where shall I connect it? L or R? Last, the GTO is not working for me. it does not turn on the LC2i. I ended up connecting it to a trigger wire.
If this is the case we will split the 2 wires into 4 and fill all the holes. You can then use both RCA outputs to go to your amp. Make sure the gto is turned on sometimes it ships off.
+Five Star Car Stereo thank you for the reply. I will do that.
Will it matter if that is connected to post amp sub? There is now way for me to tap it directly behind the nav. (2015 Genesis Sedan).
+Von Jose you can connect at the sub for signal
thank you so much. i did the install. it works great. thank you for the help!
+Von Jose sweet, glad we could help
My maximized light does not work except right after i turn the car off it comes on for about 5 seconds but nothing when adjusting bass and accubass knob
Another great video guys, most informative.
3 questions please...
Is there any difference in the LC2i and the LC2i Black, other than the colour?
As I wish to utilise the remote turn on feature, should I also be fusing the power into the LC2i?
You said the Acu base is almost like a "reverse base boost eq" my question is, If I tap of one of the 8" stock underseat subwoofers, to this LOC which will be connected to 2 12" subs. will the Acu base also restore the base curve to the 8" stock subs, as it it conected to the 12" subs?
Hope you can understand what i'm trying to describe...
Marcus.
M Henry thank you. No difference just color.
We just use the power coming from the amp, so there is no long run of power if you are going to run a power wire to the battery put a fuse at the battery. No it will not help the factory subs. They are before the LC output so the can not be helped.
Is there a way to mesure voltage output without an rta ?
hello , I have a 2014 Honda accord with the lc2i running a rockford 150x2 powering a cerwin Vega mobile hed 400 watt 12 . after installing it and adjusting it to sound good I shut my doors and have a constant bass until I open a door then it stops . I adjusted it and turned it way way down and the constant bass stopped ( btw it wasn't a bass that went with the music and was way louder) . now when I start my car it gives 3 loud bass notes like a start up or I guess to let you know its on ? do you have any suggestions in how to get this to go away ? also do you have any idea on why it was giving a constant bass only when doors closed ?? thank you so much for any help ! and you guys did a very good job on video and very informative!!!! thank you
I have a Honda Accord 2014 and do not have that issue. I used the GTO not a remote turn on. make sure the GTO is jumped to on, some that have it off and used another source of remote turn on from a fused accessory can get this. if you use a switched source make sure the GTO jumper is off. I Have also seen some by mistake put a 12V signal non switch into the remote, Another issue could be bad RCA cables they can short and cause a like issue.
I replaced my car battery and noticed the yellow light is on and solid. Now I have no sound to the sub. I swapped out the lc2i and the new one also has the solid light. How do I fix this?
Does the lc2i need both left and right input if I’m adding solely a subwoofer amp ?
Can I grab signal say from my right rear speaker or do I need both left and right ?
Thank you for a reply.
in your case you do not need both left and right as long as you at least use the left because it triggers the GTO. it will come into play if you fade to one side only. But you can use a Y connector to your cables any way.
Hey there so I don't have bass roll off so I turn threshold all the way up.. so what do i put bass on.. I notice my amp clipping a bit too soon so I'm assuming too much voltage from lc2i .. my lc2i accubass is half my main is off and bass is half.. gain on amp is half and premature clipping..
The bass adjustment setting acts like the input voltage or volume on your amplifier. They should have labeled it volume. if you have it too high and your amp too high of course it will clip. if you play a tone and have at least your radio 3/4 up adjust the bass/volume until the clipping indicator comes on, back it off until it goes off. Your volume of your amplifier should be almost off or all the way down. The unit is providing all the input voltage you need. Warning some amps cant handle such an input. . FYI, My small amplifier could not handle such a voltage of almost 9 volts. I ended up setting the bass volume at around 8-9 oclock. The main is only for additional speakers or amplifier , though it does improve bass also and the main adjustment is for the same purpose but for the main output only. if you are not using additional speakers it plays no role.
So if you are clipping lower the volume on your amp, or if it cant handle the voltage of the LC2i reduce the bass /Volume to about 8 O clock and at most adjust your bass amp 1/4 of the way not half. One or the other could be up but not both. Good luck.
someone please show how to set this up as well as the amp
Now I know they have the Lc7i but can I use "Y" adaptors so I can run a 4 channel amp for my highs and then my mono amp ? By the way love your channel you guys are great ! Wish I could come work at your shop haha
If you don't know the answer to this, then you'd be cleaning bathrooms at the shop. 😂 😃 😄
Can the main output and bass output put out the same bass levels so if I were to put two amps in with their own subwoofer on each they’ll have the exact same sound? I don’t want one sub to have deeper harder hitting bass than the other but I do want each amp to have their own set of channels instead of splitting the rcas between the two amps.
Accubass and thresh hold only works on the bass out put.
Hey any advice for setup? My Bose amp attenuates the bass signal up and down as your turn it up.
Its making tuning accubass really difficult any help would be greatly appreciated.
Example for the volumes vs bass below:
Volume at 10% has like 70% bass
Volume at 20% increases bass to like 100%
Volume at 30% drops the bass to like 75%
Volume at 50% drastically drops bass to like 50%
Volume at 75% increases bass back to 70%
Volume at 100% drops bass to like 60%.
What type of car?
Hi Dean and Fernando, Thanks all the valuable knowledge you
share. I have a PioneerGM-9605 5 channel amp on order. Would I gain anything in audio quality with an Audio ControlLC7i over the built in
speaker level inputs of the Pioneer? Going in a 2017 F150 XLT, no Sony, no nav. Standard audio.
Infinity Reference components and a Pioneer 10” shallow mount sub enclosure also coming.
Thanks, Walt
I have the exact question... I do have a LC2i don't know if I should get the LC7 or just use the LC2i since I have it and take advantage of the input functions on the Pioneer GM-D9605 . Thanks
any updates? did you pull the trigger and get the LC7i? or just stick with the built in loc on the 5 channel amp?
What's you end up doing I'm going through the same thing on a 1500watt Rms Memphis amp. I already bought this just in case I'll probably test both out and if high level input sounds as good or better I'll return it
Awesome tutorial👍🏽. Just have one question
How do you set the gains on your amp with lc2i install.
Thanks
That is a great question, we use the Smd-dd1 and also a O scope. With out those the best way is to start with the gains all the way down. Play a beat you know and repeats. Turn the radio up to the clip point. Start turning up the gain slowly you will notice a point that it stops getting louder. Turn it down a bit from that and play a couple more songs to check. Pay attention to any unnatural sounds that might coming from the woofers and turn them down or adjust the crossover.
So..what do I keep my amplifier gain levels at while tuning my lc2i? Should I let me lc2i handle gain levels and not worry about amp tunes?
That is the intent of the unit. at one point I fixed amps and found that some amps Volume all the way down was like having it off. barley have the gain on the amp turned, at most not more than 1/4 turn or less. But some amps cant handle the voltage of the LC2i so it may need to be turned down a bit. Mine is set to about 9 Oclock.
I have a couple of questions. I have a monoblock amp that I'm using to hook up my subs. Do I need to plug the remote out on the lc2 to the remote input on the amp? I'm confused by the remote in and remote out on the LC2.
Also, is it recommended I splice into my rear 6X9's or would it make more sense to splice into my factory sub? Since I'm adding a monoblock and only want bass signal...
The LC's remote out is there to turn on the amp if your radio does not have a turn on. You do not have to connect the LC's in to anything. Yes connect to your factory sub
Where did you get that tiny screw driver from?
Old video I know... But am I understanding you said it generates a remote turn on out, to turn on the amp pluged in to it? If I'm correct, would it be possible to run a second amp off the lc2i?
I use the remote out to turn on my amp
@2:42 so, it's a preventative measure by manufactures to keep from blowing out the factory speakers?
Yes, they don't want to replace subs all day. It is just one of the many problems you run into when interfacing with a factory radios. Keep in mind not all manufacturers do this, some actually just use better equipment.
Do you have to hook up both left and right speaker wire to get a good signal? I saw you just use twist both positive and both negative wire together on the pac Lp7-2.
you do not have to , as long as its full range or a mono signal. But reminder . The left side triggers the GTO in the unit, as a minimum use the left side. I used the sub output in my car and used the left side and jumped wires to the right of the unit. Later I realized I did not have to but looks good.
Okay for the main output how to I connect a 4 channel amp to it. My amp has 1-4 rca inputs but lc2i has 1 rca output
Can I use this to put 2 amps for bass and voice ?
I LIKE THAT, "I GOT ALL THE TOOLS, BITCHES!!". LOL
Can I use this to power 2 amps, one to my subs and one to my door speakers ?
4:10 Yes
Hello, I have an lc2i installed in my 2011 bmw 550i on the sub channels from the factory amp, I have the threshold turned all the way clockwise and I'm still getting no output below 28hz. When I play a tone generator thru my factory stereo after I go below 30hz the bass starts to drop off, is there something wrong with my lc2? I tried turning up the accu bass knob and gain and it only makes the frequencies above 30hz louder but not below? Do you have any ideas? FYI I'm running an AQ 3500d to 2 12" FI ssd's in a 2-1 4th order, I have 2 batteries with zero gauge wire for all.
Unfortunately in can not make up for the sounds your factory radio are not producing. It is really designed to fix volume drop off on the sub frequencies at higher volumes. You may want to look into an Epicenter if you want that fat bass sound.
What was the model of rta used in this video?
You're dry jaded humor is epic.
Could the LC2 be use like epicenter with banda music. Please let me know it would be very helpful thank you
yes it can they have two different roles. The Lc2i is mainly a line driver with bass boost. and the epicenter is a bass restoration unit that can let you restore a certain frequency and how wide from a center frequency. I can see this creating pretty bad clipping if not done right. If your amp has a bass boost like a 45hz, set up the LC2i first and add a bit of bass boost at that amp frequency. I always see this unit with all the settings set up too high almost 90% of the time.
Good demo! My question is, suppose I have a four channel factory head unit and I want to use it with a four channel amp and a mono block sub amp , what are my options?
nitestrike1000 go with the LC7i, the LCQ1, or the DQ61.
Thanks! I'll check them out
Should I use this lc2i with my d6 1200 ? Or is overkill
I am actually having trouble with a 2006 BMW 750IL I'm using ALC 7 I am getting weird sounds out of it
Hello, Can I connect the audio control at the same time to the speakers or i need disconected the speakers to conect the audiocontrol, change the impedance? because my speakers are to small and I afaird burn the factory radio outputs, congratulations for your channel , thank you
Thank you. You can tap into the factory wiring leaving the radio to play the factory speakers. The AudioControl can then go to give the aftermarket amp signal. You may want to get an amp for your smaller speakers. Then you can disconnect them and power them from the amp and actively remove the bass from them.
Just bought a 2015 Sentra and was planning on using this to add on my stock stereo because I will be adding an amp and few subs... Now I read a few spots that this will also help the output of my stock speakers(front door and 6x9s) also without having to run an amp to them... Is that true? Thanks fellas
It will only help them if you run an amp to them. It has no EQ or sound better feature unless you use an amp.
+Five Star Car Stereo ahh ok. well I already ordered it, so all good lol. Will deff help out with my amplifier running to my subs tho yea?
+PacmannProductionsTv yes it will do wonders for the sub on a factory radio.
Great video!!! i have 2012 ford fusion with sony system that and a factory amp the OEM stereo comes with 10 speakers. I am hooking up an amp and sub with tweeters built into it. To get the signal for LC2i L/R speakers should i splice into door speaker wiring or the 9' built in factory speaker at the rear. which wiring will give me a better sound so i don't have all bass or all high frequency? thanks
gurps kang I was wondering the same thing with my Taurus SHO. The rear 6 x 9s supposedly only reproduce low frequency I don't know whether to splice those or the full range door speakers. Did you ever figure this out?
Kenneth Niswonger I didn’t bother connecting the line output converter yet. From I got it’s better to go with the door speaker wires for the signal. The converter has a built in bass control for the subs. I hope that helped.
If you plan on adding another amp to drive speakers up front use full range to use the Fix out. Otherwise tapping into the factory sub is all you need.
what is that other device beside the lc2i? can you give me the make and model number of it?
Little warning.. as you increase the threshold there is a slight delay in response to that setting.. make small changes and wait.
ISEE YOU yes, good tip. Thanks for sharing
I'm putting 1000 rms jL in my 2015 Will it handle that
Is it better for the threshold to be maxed or somewhere in the 50-75% range?
+Mk if you car does not have a volume loss turn it up all the way
Would this work on on 2019 Chevy impala factory head unit I hear distortion was caused by the factory head unit when a 4 channel was installed
Adante Paige you might need the lc6i
My factory bose amp stop playing my subsides a loud humming noise is the part on the board buried out please respond
