Features
- Upgrade your audio system while keeping your factory stereo: Convert speaker-level signals up to 400W per channel from your OEM radio or amplifier to high quality pre-amp output signals directed to aftermarket subwoofers, amplifiers, and processors.
- Maximize your bass: AccuBASS processing technology corrects and restores bass roll-off when the volume is increased on the factory radio.
- Save vehicle space: A compact slim chassis with integrated mounting brackets enables quick and easy installation without taking up extra room in your car. Dimensions: 5.4L x 3.25D x 1.5H (6.5L including mounting brackets).
- Retain important factory features: Including the use of factory volume and steering wheel controls.
- Gain full control over your sound: Fixed and variable outputs with discrete onboard level controls allow you customize your audio and make adjustments easily. *Does not retain fader control when running multiple amplifiers. For applications where this is desired, use LC5i PRO, LC6i, LC7i, LC7i PRO.
- Control subwoofer levels from the drivers seat: Includes optional input for adding the ACR-1 dash knob remote (sold separately).
- Choose your turn-on mode: Features selectable Great Turn On (GTO) signal sense to automatically power the LOC or remote 12V input for manual control.
- Turn on your other devices: By using the Remote Out, this line out converter can trigger up to 2 devices down the signal chain including amplifiers, line drivers, crossovers, or any other device with a Remote In. *Compatible with most but not all vehicles. A remote turn on wire may still be required.
- For best results, the +12V should be provided by the battery via a direct line or from a power distro-block. The preferred wire gauge for the connection is an 18 AWG, and a 1A fuse is recommended.

Size: LC2i without Wired Remote
The AudioControl LC2i is an excellent solution for adding an aftermarket amplifier and subwoofer to a factory stereo system. It makes installation much easier by converting the factory speaker signal into a clean RCA output while maintaining great sound quality. The AccuBASS feature is a huge advantage because it helps restore the low-frequency bass that many factory systems reduce at higher volumes. After tuning it properly, the bass output is much stronger, deeper, and more consistent. The build quality is excellent, and the controls are easy to adjust for getting the perfect sound balance. Installation is straightforward, and it works reliably without introducing unwanted noise or distortion. Overall, the LC2i is one of the best line output converters available for upgrading a factory audio system. It delivers clean signal processing, great bass restoration, and professional-level performance. 5/5 stars.

Works like a charm, no long remote wire to run but it does require its own power and ground so take that as you will lol. Set up was easy the only thing I had a hard time with was figuring out how the input connectors work but once you get it down and mount it tight it’s a great LOC with enough tuning capabilities and versatility for all model years. I drive a 21 civic and everything hooked up real clean, 10/10

This thing is generally known as a good LOC. I will have to add to the many 5 star reviews but it is so important that you wire this thing correctly and take your time tweaking your settings. At first I was pissed because the bass was too low and then it was too high! Watch the videos and read the articles and take your time setting this thing up. Everything works like it is supposed to. If you aren't getting the desired results, don't write a bad review and return it right away. You really have to make sure all your connections are right and your speakers are broken in before you can appreciate the difference in sound quality this thing can add to you factory sound system. I almost returned it because I thought the AccuBass feature was broken but then I realized I had one channel reversed at the speaker level input and it was seriously degrading the sound quality of my entire system. Once I got the polarity right, DAMN! The sound was incredible! I actually had to turn the bass DOWN because it was overpowering the mids and highs up front! I read some articles about the RCA's being out of phase and I didn't understand it but after messing with the wires I figured out that it can make a huge difference in performance. Proper wiring MATTERS! GTO works perfectly for class D and class A/B amps. Makes it easy because you don't have to go looking for a 12 volt that only turns on when you turn the key. This thing outputs a signal high enough signal that I have the gain set to just over minimum on both my amps and the sound system BANGS! I have a 2022 Corolla and I got my speaker level signal from the dash tweeters and ran them to the trunk to connect to the unit and then split the output to a 4 channel amp for the door speakers and a couple of 8" subs on the bass output and I am amazed at the power. I will write more details and maybe even start a YouTube channel on my experience but if you are scratching your head, give me a message and I'll tell you everything I learned. This thing rocks. I will soon be upgrading to the Lc7i so I can utilize the head unit fade controls but even this thing kicks ass. Oh and BtW, I turned the threshold control all the way to the left to disable the AccuBass feature and my system still gets louder with every click no matter how far I go. The max level on this car is 63 (weird number) so I don't even need the bass correction because my head hurts and my eyes pop out after 50! My dudes, this thing kicks so much ass I wish I knew about it sooner.

I installed this on my 2006 BMW 330i.with factory radio. The bmw factory amp wires going to factory subwoofer is where I tapped into to get my high level amp signal. The signal converter that came with my new amp was allowing the full power about 40 watts to pass to the rca input on my aftermarket amp. The aftermarket amp would go into protect mode at 50-60% volume. I installed the lc2i with accu bass and it solved the problem. It was very easy to tune and Sound quality is great. I love that it has the high level sensing to turn it on and the remote out also powers up which i use to trigger the amp. This unit restores the bass thae factory radio reduces at higher levels also. Very happy with it.

This LC2i converter is such a great device. I installed into my 2012 Honda Civic with ease by tapping into the factory sub. I’m currently running two 12” Rockford Fosgate Punches powered by a Rockford Fosgate Prime amp (2400 Peak/1200 RMS @ 1 OHM). Everything works great, my subs get continuous power and the installation was super easy (with some YouTube help). The only knock I have against this is the sound quality. The initial bass won’t come on until after the lc2i gets power and sends it elsewhere so there is a delay initially to turn your amp on, maybe a half a second delay). Also, if you push some decent power and turn it up it seems like the bass delays itself and isn’t on beat anymore. I plan on adding a capacitor to my setup to see if that helps. Will update in future

I recently installed the Skar Audio SVR-1X10D2 loaded enclosure, paired with the RP-800.1D amplifier and an AudioControl LC2i, and I couldn’t be happier with the results. The subwoofer enclosure is extremely well-built and tuned perfectly for deep, clean bass. It delivers impressive output for a single 10” setup—tight, responsive, and capable of hitting surprisingly low frequencies while still maintaining clarity. The vented design really allows the sub to breathe and perform at its best. The RP-800.1D amplifier has been a perfect match for this setup. It provides consistent, reliable power and stays cool even during extended listening sessions. The included remote bass knob is a great touch, making it easy to fine-tune output on the fly depending on the track. Adding the AudioControl LC2i made a noticeable difference in signal quality. The AccuBASS feature helps restore low-end frequencies that can get lost in factory systems, resulting in a much fuller and more dynamic sound. Overall, this combination exceeded my expectations. Installation was straightforward, build quality across all components is excellent, and the performance is outstanding for the price point. I would absolutely recommend this setup to anyone looking for a powerful, clean, and well-balanced bass upgrade.

My old unit went out a few days ago, so I decided to try this one as a more affordable replacement. Setup was super easy, and to my surprise, it actually performs better than the more expensive model I replaced! The sound is cleaner with noticeably deeper bass. I’m genuinely impressed and would highly recommend this to anyone considering it. In this case, going with the cheaper option turned out to be the better choice! However, I will say they could improve their quality control when it comes to packaging. My box arrived cracked, and the unit was a bit dusty—as if it had been previously opened or stored improperly. It still works perfectly, but a little more attention to packaging would make the overall experience better.
