AudioControl LC2i PRO 2-Channel Line Output Converter with Wireless Qi Universal Phone Charger Kit. Impedance Matching, AccuBASS, GTO, Audio Signal Sense, 12V Turn-On and ACR-1 Dash Remote Sub Control

Love it!!!

Made connecting to factory radio a breeze. Installed in my 2017 Tesla Model S and absolutely love the output. Definitely recommend to anyone looking for n easy install.

For years I was running a cheap active LOC in my 2014 hyundai veloster turbo, and I wanted more from my subs. I'm running two alpine type R's (swr-10d4) 1000W RMS each, wired to one ohm on a Hifonics Brutus (BRX2000.1D) 2000W RMS @ 1 ohm.I wanted to upgrade my prefab box thinking this was my issue. I did some research and found that I have my gains set too low and after setting this to the proper level it sounded louder but still sounded distorted. It was then I understood my cheap LOC was the reason why, I was getting distortion with barely any preout voltage (had to turn my gain 'way up' to match the low preout voltage.)I decided to bite the bullet on this LC2I. I tapped into the factory subwoofer and played a 50hz 0db test tone through my radio, set at 30/35, turned my level up on my LC2I until the maximized light came on, then backed it off a little. To set my gains on my amp, I took the square root of my 2000w amp multiplied by the one ohm to get my target voltage at the amps output terminal (44.72 V)I then tested my voltage with a DDM at the amps outputs terminals and used the amps gain knob to achive my target voltage of 44.72. The gain was turned down substantially compared to when I was using the cheap LOC, proving the new LC2I was providing a higher preout voltage.The quality and clarity of the subs are now night and day different. I wish i did this upgrade alot sooner. This was well worth the money spent, and if you are using a cheap LOC and looking for more out of your system this is a no brainer. Just do it.

If you're like me and have a newer vehicle with lots of factory options that run through the head unit, going aftermarket can be a huge pain in the rear. This active LOC has crystal clear sound output without all the engine noise and muddy sound processing from a budget aftermarket setup. Works even better if your car has a factory amplifier with a low frequency output. It's also fairly easy to install whether you have very little experience, or many years of car audio under your belt. There are also some very easy to follow youtube guides that explain all of the features and how to easily set them.

So... if you are trying to add an amp or multiple amps to a stock radio you cannot spend money on your new set up without this! Way better than passive line out converter. Well worth the money. If you can run the power for your amp you can hook this up. Tapping into your stock speaker is easy enough. AMAZING difference in performance on my amp. It runs way cooler.The only reason it's not 5 stars is the lack of seeing/tuning instructions - clear as mud. The Acubass is awesome but confusing and difficult to tune. Although it did scare the s**t outta me when my head was in the trunk and it kicked in. Insane on the difference it makes.I am running a pair of Rockford Foster R2 10's with a Rockford Fosgate Prime 500.1d amp.Loud enough for the neighbors to come outside and think it was the teenagers down the street (not the 50 year old neighbor)

Manages my 2 1500 rms amps and 4 8” subs in my f-150. I split off the factory 8” sub in the back and wired it to the lc2i. I’m exited to use this product further because I will be building a speaker wall and will use the other main output to control that aswell.

So accubass can give you a low boost, but I don't run it at all. It's not gonna completely fix the low end in my experience it's a trade off. It'll make some hip hop songs boom, but then you'll need to adjust for others. Rock is even more variable. Bass guitars get messy with the accubass. Metal sounds okay with double kick bass. Grunge, alternative, hard-core, punk are too fast for it. Or something because holes develop and it just adds garbage to the sound. Not using accubass I love the line amp. Music sounds good in all genres, and I'm getting less distortion now. It can handle crazy inputs and vary it's rcas with crazy output power. Just have the right expectations going in. You don't want two bass knobs, it's nice to be able to use the eq in dash instead of accubass.

Definitely recommend if your system is stock. This will help bring the true output your subs need. If you have an aftermarket head unit this won't be needed. I wanted to retain the oem unit at least for a while until I find an aftermarket one down the line(money). Installation wasnt too bad, found a few youtube videos that helped. Works great, and the remote bass knob hasn't had any issues. The old Skar remote bass knob took a crap so hopefully this one is better quality. These are Skar SVR series 10" in their enclosure. I'm sure a custom box would be a better upgrade, but this hits pretty hard for now.
