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.
  • Gain full control over your sound: Dual variable stereo gain controls and an LED clipping indicator allow you customize your audio and make adjustments easily.
  • Control subwoofer levels from the drivers seat: Includes the ACR-1 dash knob remote, a 20-foot remote cable, and metal housing with integrated removable mounting tabs for custom flush mount installations.
  • 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.
  • Eliminate noise: Selectable ground isolation switch allows you to remove ground buzz or alternator whine.
  • 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.
  • Seamlessly integrate with late model vehicles: Onboard load selection switches allow factory amplifiers in modern systems to detect speaker loads and continue passing audio. Choose between 20 ohms, 60 ohms, and 20k ohms.
  • Save vehicle space: Designed with a compact slim chassis (6.9L x 3D x 1H including speaker connectors).

Description

The LC2i PRO join ranks with AudioControl’s most popular active line output converter, the LC2i. Adding a sub? Planning a full system? Either way, get the best possible signal from your factory sound system to your amplifiers. Load selection switches mean OEM integration has never been easier and the LC2i PRO will work with the most finicky factory sound systems. Installer friendly turn on trigger modes allow for flexibility via GTO Signal Sense (DC offset), audio sense, or remote 12 volt inputs. Compensate for factory bass roll-off with AudioContol’s patented AccuBASS and control your sub with the included ACR-1 level control.

    • Great Product!
Awesome Product! No issues and setup was a breeze! I’m using a stock MyLink Chevy Headunit and works like a breeze once you figure out the wiring diagram! Well worth the money with the added option for load setting and ground options if having issues with alternator noise

    • Makes it so easy to add an amp and sub to a factory amplified system.
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. ... show more

    • Love it
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) ... show more

    • Plenty of Bass on tap now. Say goodbye to bass roll off
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.

    • worked great, till it didn't
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.
