## Overview

The AudioControl LC2i PRO is a compact, 2-channel active line output converter designed to upgrade factory car audio systems by converting high-power speaker signals into clean pre-amp outputs. Featuring patented AccuBASS technology, dual gain controls, and a driver-accessible remote bass knob, it seamlessly integrates with modern vehicles while eliminating noise and preserving sound quality. Ideal for adding subwoofers and amplifiers without replacing the factory head unit.

## 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.

Review: It made a noticeable difference - 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.
Review: Detailed review - 50,000 mile review. It's perfect. Does exactly what it's supposed to do. Works well with 16v input even though it's not advertised to. Compatible with any vehicle including my 2023 Tesla model 3 performance. Very durable. Sound quality is not an issue. Expensive for the money but you know you are getting a great product.

## Questions & Answers

**Q: I have a prius with the factory jbl system. will this work by tapping the rear door speakers?**
A: The LCi requires a full-range signal to work properly so more than likely use the front door speakers as an input, remember you are piggybacking off the wires so the speakers you get the signal from will still be operational. Hope this helps!

**Q: Can I buy just the bass knob**
A: It's been a while but the last time I was on you were able to purchase a base not by itself just put up on your search bass knob for whatever you're buying

**Q: are these just for stock radios or can one install this on a aftermarket stereo?**
A: You can put it on any radio. There’s really not a reason to put one on an aftermarket radio. All your doing is putting in a rca hookup for the amp. Most if not all aftermarket HU’s come with rca hookups now. 
On a side note if you do need one, shop around. This is junk. And way to expensive. I’m about to just buy a amp with high level hookups and trash this LCi2 it’s junk

**Q: will this work on a 2016 audi with bose fiber optic system? Ive tried a different LOC and when its attached to the speaker wires the I lose signal.**
A: Not that I'm aware. Best bet is to call Audi to verify
