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.

I originally put a passive Scosche LOC in my car when I couldn't find low level outputs on my factory system. It popped and clicked and the bass was missing at the low end of things. I replaced it with this (and mounted a level control knob), and things are sounding dramatically better. The signal was so weak on the Scosche unit that the bass would drop off in certain ranges even though I was tapping the high level lines for factory door subwoofers. The little white Accubass threshold knob on this thing allows you to adjust until the bass "pops back in" at lower ranges. The manual was a bit short for my tastes, and I am not sure what each knob does or does differently from one another. However, this thing really boosted my signal and has added in about 50% more low end punch. Before I got this I was disappointed with my setup. I previously always had high voltage preamp outputs to use from aftermarket stereos with my installs. With this thing, the sound level stays consistent with the volume instead of ramping up only at high volumes like I got on a passive unit and things sound to me much like they are coming from a clean preamp signal. Something I really liked about this was the fact that the terminal ports can be unclipped from the unit if you want to work on them separately. This makes it a lot easier to wire in a tight space and then snap them back in when you are done. The unit is fairly weighty and long, so it was a difficult fit for me where I needed it on the wall under the dashboard. All in all, I would get this thing if you need a LOC. I balked at the price initially, but this thing is worlds better than the scosche units. Overall it is worth the price, and the construction of this thing makes me believe it will hold up long enough to be used in future installs if and when I change vehicles. Don't waste time with other LOC's with mixed reviews. You will be end up paying for two when you buy this to replace it.

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.

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.

I installed a new amp on my door speakers recently with a passive line output converter. I immediately had tons of the dreaded Alternator noise. I spent two weeks troubleshooting. Everyone kept telling me it was a ground loop but nothing I did made a difference. I finally decided to drop the money on the LC2i active LOC and instantly the noise is gone. My system sounds awesome now. This unit works great. My only issue is the threshold trim pot for the accubass. I tried a couple of different size small screw drivers and it's really hard to get a feel for when you are actually turning it. I know they moved this knob on the Pro but it still seems like this one could use a slight modification. Solid purchase. Worth every penny!

Works just like I had expected. previously I used a non powered LOC, and it was obviously low quality. If i remember right it was like a 30 dollar random brand thing from best buy. alternator whine, speakers popped when system turned on, balance was way off, etc etc. every problem I experienced was gone as soon as this turned on. GTO (basically an automatic signal sense which turns this on as opposed to remote turn on) works perfectly for me. No delay or anything. which really isn't that awesome of a feature. but it did save me about 10 minutes of splicing my remote turn on for a third item (low and high amps and then this) Installed in a 2010 F-150 lariat with no navigation or premium sound. While it sounds good, I had no previous problems (that i could notice) with my Low hz being cut off. so I can't speak to its ability to eliminate that problem. This setup does however allow me to keep my factory steering column controls, sync, etc etc...which is great. Only con I really came across is the fact that it doesn't ever really tell you to install a fuse unless you pay special attention to the specifications listings which "recommends" you install a 1 amp fuse. And the only reason I knew to do this was because a previous powered LOC I had blew up because I overlooked the same detail. Not really a hardcore con to the product. Especially, since if you pay attention, the information is there. Just something to keep in mind. I installed with a 1/2 amp in line fuse rated at 12v, so far works fine, just didn't have immediate access to the 1 amp fuse so I figured I'd try this first. No harm in going on the conservative side. I suppose another thing to mention is the fact that it does not come with any wires or fuse holder or anything, so plan ahead and don't expect to just plug this in with included hardware. Most likely my next step will be to buy a equalizer to help balance out my highs (and possibly something for the lows too). this is just due to the fact that my truck has nothing except a rudimentary treble and bass adjustment. If your head unit has some more features this may be all you need, since the adjustments you make to the head unit still apply to any signal sent through the LOC. Last thing I'd like to leave you with, this thing really opens up your system (if your coming from a OEM factory head unit) to cranking the bass way the heck up. I ended up leaving all my gains neutral and turning the "accubass" adjust down to minimum. Someone with more beefy Subs than me (two 10" shallow mount pioneers) may have more success in cranking it up, but for me, it only drove my speakers to max way to early.

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.
