AudioControl LC2i PRO 2-Channel Line Output Converter with AccuBASS | Includes ACR-1 dash remote bass knob, add subwoofers or amplifiers & retain OEM head unit, car audio sound system upgrade

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.

Simple install, easy to use, just what i needed. I added this to my vehicle that had a factory amplified sub already. I made a harness that plugged into to factory wires and ran it to the LC2. Super easy. I setup the LC2 to auto turn on. Super easy. I used the remote out to turn on the amp. Super easy. I didn't have to find and run a remote wire for anything. Super easy. It does what I needed it to do. It plays lower than what I expected. Im not positive, but it seems the bass roll off is under 30hz. It doesn't get much easier.

Quit working right after the one year warranty ran out. Update: contacted audio control and they honored the warranty even though it was a little passed the one year mark. Great customer service that stands behind their product.

Best inline converter if you want to put an amp on a factory radio!

Mannnnnnn I got some smooothhh tunes coming out my Whip! No issues easy to install and now my subs are doing there thing.

4 stars just cause I didn’t get the pick

I used this on a BMW M5 with the stock sound system and was very impressed. Installation was straightforward and easy to complete. It made a noticeable difference in correcting the frequency curve and really improved the overall sound quality. Highly recommend for anyone looking to upgrade their factory system without a complicated install.

If you have a Ford you're going to need this. Trust me it will wake up your subwoofer or any speaker thats behind it. Super easy to install and take your time with the adjustments to get it right. Watch youtube videos and you'll get it.

These things are awesome. Haven't hooked up in my Mercedes to the factory Burmeister system so that I could run a 10-in sub for some fill and it puts out a beautiful clean signal. Anybody that rates these low has no idea what they are doing with car audio or it didn't take the time to learn how to set them up properly which really doesn't take very long if you have a brain.

Llegó sin el control a distancia, si bien decía que el producto estaba ya abierto, comentaba que contenía el mando a distancia el cuál no llego

My son ordered for his Cadillac and works great

Amazing

Although these are primarily used for car audio to enable addition of amplifiers and subwoofer to a factory radio , I used this as a home receiver tool to add pre-outs to run my Center channel from a secondary amplifier. This allowed me to run 2 Center speakers together bi-wired using a channel A+B amplifier as secondary mode. To power it, I repurposed a USB Sata adapter power supply ( for external drives) and was able to run a trigger wire from the main receiver to power it on at the same time as the main receiver. I was very happy with the result. It widened the presence of the Center speakers (2) considerably and sounded awesome.
