LC2i Training Video

[@oso_Peligroso]

I have one of these and had NO idea it had as many features! I was just thinking earlier today that I need a bass knob. I googled RCA knobs but come to find out I just need the Audio Control one. COOL!

Why does the lc2i put out signal at power on with the volume all the way down? You can see it in the RTA in the video @ 2:52.I can hear it, through my woofers. it’s a low hum!

[@AudioControlCar]

Generally, this is due to most source units still putting out some signal, even with the volume all the way down. If you want to eliminate this, you can use a true turn on lead rather than using the signal sensing GTO turn on. Many times the hum heard in demo/training videos is produced by the 110v to 12vdc power supply, which wouldn't be an issue in an actual vehicle, of course.

[@clutchymaster151]

So we can use the knob like an epicenter? Does that mean i can save money

[@PaPiSwinGTV]

Hey i cant hear certain bass sounds and certain instruments on my system. Why is that happening??

[@TJsVette]

Would you use this for a aftermarket radio that only provides .8v to the sub rca on the back of the radio?

[@keving1774]

When it detects a signal it sends a big thump to the subwoofer and makes that pop sound. Using the remote out on the LC2i to the amp helps minimize it...

[@michaelmeiier3736]

So I setup my lc2i changed nothing about the setup except vehicles, and now with my stereo volume at 0, my subs still hit. Why?

[@michaelr1624]

Do I need to use the actual speaker wire or can I T-off the speaker wire and plug in the new wire to the LoC? Thus the speaker wire is still connected to the speaker and is playing.

can i use stock signal from my stock sub on my 13 ram 2500 to lc2i?? or it have to be from door speakers?

[@AudioControlCar]

You could use either one, but many times the front door speakers have a more useable frequency range and your aftermarket system will often sound better using that front door signal rather than the ohm sub signal. You could certainly try it with either and compare though, it won't hurt anything.

[@brianmonger3452]

So I get that you pull signal from the existing speaker wire. But does it matter if it's before or after the factory amp and if the factory amp only powers the factory sub can I pull the signal from the inputs of the factory amp so I could remove it from the vehicle or should I get it from the rear speakers?

[@SoDiezl350]

If you're only using the LC2I for an aftermarket sub, then the best place to tap into the speaker would be at the high level sub input.On my f30 bmw I was never able to get the lc2i to read the preamp signal coming from the head unit. On certain factory stereos, the head unit needs to see a load. The lc2i pro has an adjustable load feature, but the unit shown here does not.

[@AudioControlCar]

Generally speaking, in most all vehicles, you'll want to obtain your signal for the LC2i or LC2i PRO from the output side of the factory amplifier. A line output converter like these is taking a high level signal and converting it to a low level signal. So chances are, you won't want to use the low level signal going into your OEM amp for signal. You'd end up with little to no volume.

[@MrPaco137]

Can you ADD a Digital Bass Processor (epicenter) between the LC2i and the power amp for the subwoofer ? Hi from Fresnillo Mex. Thanks

[@luisaceves2728]

lakermd before the factory amp, it’s going to amplify your amp with cleaner power

[@AudioControlCar]

All of our products can accept signal from the outputs of an OEM amplifier. So if your vehicle has a factory amplifier, you can grab signal from it's outputs, feed that into our product's inputs, and end up with a nice clean RCA signal to send to your aftermarket subwoofer amplifier.

[@kmother19]

Mark, Do both speaker inputs need to be connected for the lc2i to turn on with the gto feature?? I only have access to one speaker at the moment to tap into.

[@murdertown69]

Question? When hooking up speaker inputs, does it matter what stage you use to hook up the lc2i! Like does the product need to be hooked up to the front stage wiring or rear? Does it matter?

[@AudioControlCar]

Good question! It really depends on what you're using the LC2i for. If you are just adding a subwoofer amplifier/sub, then it really doesn't matter, so long as the signal you tie into has enough bass information present. If you are using the LC2i to add a full range 2ch or 4ch amplifier, the same applies. You would just want to be sure to tie into a signal that has the correct audio information present. Also, be aware that depending on what channels you use for signal, your fader may affect the output of your aftermarket amplifier/subwoofer.

If I'm only hooking up my subwoofer (with amp) to the lc2i where do I get the speaker wire from?

[@AudioControlCar]

You can grab signal from any speaker(s) in the vehicle that have enough bass in the signal presently going to them. Play a song with some bass in it, listen closely to each speaker (Put your ear up to it even?) and try to see if you can hear the speaker playing some bass. If you can, that speaker should be ok to grab your signal from. Remember, you don't have to disconnect the speaker either, you can just tap into the wires leading to it. If not, give our tech team a call at [phone], Mon-Fri, 9am-5pm PST.

[@kevinski175]

When adjusting the gain knob on the LC2i for my aftermarket sub, is it the bass knob or the main knob?. Also should I have the gain on my amp all the way down when adjusting the gain knob on the LC2i?

[@AudioControlCar]

Yes, start with the gain knob on your amplifier in it's lowest position. There are output controls on the top of the LC2i- MAIN and BASS. The MAIN knob controls the output level of the MAIN output RCAs and the BASS knob controls the output level of the BASS output RCAs. So the two knobs correspond to the two pairs of RCA outputs. Hopefully that makes sense- if not, give us a call sometime and we can help you through it.

What settings is door Speakers

[@poxcr]

I installed a JBL BassPro SL2 powered subwoofer on my 2016 Volkswagen e-Golf (non Fender audio) by tapping the front speaker output wires 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 almost 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 Audiocontrol LC2i instead connecting directly to the sub’s high level input would make any difference.

[@legittaco4440]

I’m very confused I had this installed by a friend who is knowledgeable but here is my question. It says it only puts out 400W per channel. I am only using the subwoofer channel right now. I have it connected to an amp that can put out up to 1400W. But since the audiocontroller can only put out 400W isn’t that limiting my amp to 400W?

[@AudioControlCar]

The AudioControl LC2i (and most other AC products) can handle 400 watts of INPUT to their speaker level inputs and convert it into up to 9.5 volts of RCA low level output. Basically, taking an unusable factory signal and converting it into a usable signal your aftermarket amplifier can handle. The LC2i will have no effect on the actual wattage produced by your amplifier. It will work with a 100w amplifier or a 10,000 watt amplifier, but it will handle the signals the same way. So thankfully, your 1400w amp is not being limited in any way. You're on the right track, just getting a little mixed up in the specs/terminology. Hope that helps!

My radio starts clipping at a little passed half way. Will intalling a LC2Ipro be better than using my amps high level inputs to get my amp to play at higher volume without blowing my sub?

It's so hard to find a damn video. Where someone explains. What speaker wires you really need to hook up?

No one explains that at all, ever, never.

[@smgboatshouston]

Did you ever happen to figure that out?

[@Robotescu]

Bass is not always mono, even if it doesn't make sense. Some tracks will sometimes favor right channel, other songs will favor left channel, and i noticed this when i set stereo subs to my home audio system. When you connect both channels to lc2i, i suspect, you get a proper mono, so your bass will work the same no matter how the song is mastered.

[@jayholt2101]

Question- If I use the bass knob on the LC2i do I still need to run a bass know for the subwoofer amp or can I just run a bass knob for the amp itself?

[@JerseyPiney]

You can run on knob from either one that you want. You don’t need one on both. Either or do the same exact thing.

[@MidnightMarrow]

In theory the LC2i is a cleaner source so boosting it before the amp might be more ideal, though I'm not 100% certain. But boosting a signal can add noise and with that could cause clipping and the like. So if the LC2i is indeed cleaning up and processing the audio, boosting it there might be where you'd want to do it while keeping the amp neutral.

[@JerseyPiney]

MidnightMarrow the Bass knob for both are just attenuators. They don’t actually boost anything at all. Maxed out they just match whatever signal the output knob is set to. So the addition of one would just give you the option to lower output at the twist of a knob.

Check your remote wire is properly installed into an ignition wire or a fuse that turns on with the vehicle when the key turns and then back off when you turn off the car.

Hello sir, great video! I do have a question were are you getting your power source from? Straight from the battery?

[@heathcolwell9190]

Run a jumper from your amp power lead

[@socademon]

Can the LC2i run both main and bass output at the same time?

[@AudioControlCar]

It sure can! It is designed so that both sets of outputs are always functional. No need to switch them on/off or anything like that. Just plug in your RCA's front the LC2i to your amplifier(s) and go.

Great video very informative. I have a question . My factory subwoofer is a dual voice coal. Should I tap into all 4 wires or just 2 ?

[@pedrorubio950]

Also should I cut them or just tap into them ? 2011 Toyota 4Runner JBL subwoofer

[@AudioControlCar]

Generally, just one pair for signal will be fine, when only adding an aftermarket subwoofer. If you want the OEM woofer to remain active, then just tap in. If you'd like to eliminate the OEM woofer and only have the aftermarket sub playing (recommended) then disconnect the OEM woofer completely. Hope that helps!

[@HOHOHOMOFOS]

@@AudioControlCar so I would need to disconnect the oem subwoofer and run both speaker wires to get the full potential out of the aftermarket sub??? I'm running a apocalypse AAB-2900.1D and a apocalypse 270 15 d2 and I'm having the same problem at half the halfway point on the bass knob

[@GDBAKED81]

Do you recommend hooking up both rear speakers or can I us one?

[@jorgeramos9525]

Need to hook up both for stereo left and right 👍

[@MrRotery7]

Love the vid! But do i have to hook up both speaker inputs or can i just use one?

[@AudioControlCar]

You can use just one, if you need to, but you will then only get output from one of the RCAs. So, if you only have one channel of audio (one + and one -) to work with, we would recommend using short jumper wires to make sure that both the L and R inputs are populated. Check out this link where we explain this further in detail: www.audiocontrol.com/knowledge-base/factory-head-unit-mono-output-can-just-send-mono-signal-lc2i/

Good question, excellent answer, thank you

[@aaronsharp241]

Does this have a built in line driver?

[@fullpeladas]

Aaron Sharp yes

@@fullpeladas thanx brah

[@jcook8191]

Can you use this unit for 6 ch? Front, rear, and sub? Using two amps

[@AudioControlCar]

You would want to look at our LC7i device.

[@adlerdefender8067]

It depends on the amp... Pioneer, Alpine and kicker make multi channel amps that can work with one set of rcas only

[@fullpeladas]

Sorry its late but yes all need is y rca adapters for main output to convert 2 rca to 4 rca.

[@adlerdefender8067]

@@fullpeladas nope.. is best if you get the amps I mentioned 😉

[@decid3]

@@adlerdefender8067 If you please, why wouldn't the y-adapters be sufficient in this case? I'm just about to do this exact thing. Thank you in advance.

[@jayjb833]

So just subwoofer adjusted!! All the wire work and can’t even adjust door speakers !!

[@ivantribe]

Where do you get the 12v power from???

[@jayholt2101]

Run a 18gauge wire with a in line 1amp fuse straight from the battery.

[@MidnightMarrow]

@@jayholt2101 If the amp and LC2i are close by, you can connect the 12v into the port of the amp itself as it's coming off the battery already. No need to run long lines for both. Also because the LC2i has the GTO feature, you also connect the remote OUT from the LC2i to the remote in of the amp and once the device detects signal from the left channel, it will turn itself on as well as the amp you've connected to it!

[@worldwar3tactical494]

Awesome video! What's the best gauge/ type of wires to use to connect speakers, power, ground and remote?

[@AudioControlCar]

Thank you for the kind words. For power/ground/remote/speaker level input wiring, we recommend 14-22g wire, depending on the length of the wire run. Typical car audio primary wire will be 14-16g, and will work just fine.

[@chrisduncan2400]

Lc2i has a built in high pass filter at 33hz. The pro does 20hz.

[@xxah54nxx]

What do you mean by this? The lc2i won’t play under 33hz?

[@chrisduncan2400]

@@xxah54nxx it means it falls off rapidly under 33hz. I changed it out for the pro and the lows are much better.

[@PhatkatCollections]

I've had this for a few years and since day one the gain knob does absolutely nothing. No volume change at all. The optimize light never comes in no matter where the gain knob is set. I think this is a lemon , sounds no different then my 20 dollar pac loc

[@RedBeardRebass]

sounds like it's not hooked up correctly

[@PhatkatCollections]

@@RedBeardRebass nope hooked up correctly. I didn't realize that the bass adjustment was not actually a bass adjustment but s gain knob for the bass rca output. The gain adjustment is actually the gain for the main rca output. Kind of a confusing way of labeling the adjustments but I get it now. Once I went back and messed with it it I figured it out and optimized light started to come on. So far so good.
