I recently upgraded to this unit from the LC6i because I needed the Accubass to restore the bass that the factory radio was attenuating at higher volume. It did exactly that and gave my subs the clean bass signal that they were meant to reproduce. The clarity and balance is amazing, coupled with the power of my amplifier my system is better than ever. If you must keep your factory system intact while adding power and aftermarket speakers and subs, this is the product to help you do it. Be sure to buy it from Sonic, I received mine as a gift someone bought from the Big Blue electronic store...I could have saved that person $70!

For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better".
LC7i - 6 Channel Line Out Converter with Accubass™
The AudioControl LC7i, six channel active line converter, allows all music lovers, who want a great in-car audio experience, to keep their factory installed source unit and dramatically improve their system performance. The LC7i delivers amazing sound quality and fixes one of the biggest letdowns of today's factory systems, weak BASS!
Designed for maximum sound quality and enhanced audio performance, the LC7i is the latest AudioControl processor to incorporate AccuBASS™. This patent pending process automatically corrects for the bass roll-off that is common with many factory-installed audio systems and AudioControl's unique and exclusive AccuBASS™ patent pending circuitry maintains and restores the Bass as the volume is turned up, improving the audio performance.
The LC7i allows the flexibility of powering the audio signals downstream to single or multiple factory amps maximizing sound quality & achieving high output at a great price. In addition, the LC7i is designed to fit into a compact chassis allowing an easy & flexible factory system upgrade in today's space constrained vehicles. The ACR-1 dash remote (sold separately) allows the user to control the level of the low frequency output.
Most factory speaker systems are not capable of loud, clean bass reproduction, all in order to "protect" the OEM Speakers. This is why many car manufacturers restrict bass frequencies at higher volumes. AudioControl's AccuBASS™ Bass Compensation circuit corrects the roll off that occurs at high volume levels, delivering killer bass at all volumes! The AccuBASS circuit automatically engages at a preset volume level and reverses the factory bass roll-off to give you the music the way the artist intended it to be heard.
Internal Channel Summing:
The LC7i has the unique ability to internally sum together multiple (4 or 6) input channels from the factory source unit into 2 channels. This is particularly handy when using the LC7i with a factory system that has multiple, actively crossed-over signals being sent from the OEM source unit or amplifier(s). For example, in some vehicles there is an actively crossed-over tweeter, midrange, and woofer all in the front of the vehicle. The LC7i lets you take all of those signals and sum them together to get a high-quality, full-range, pre-amp signal without the use of any additional cables or hardware.
GTO™ Signal-Sensing Inputs:
Most factory-installed source units lack the features that make it easy to upgrade with really good-sounding, performance aftermarket products. One of those key features is a 12-volt trigger that will turn on devices like the LC7i and your external amplifiers. Therefore, we have equipped your LC6i with our unique GTO™ (Great Turn On) signal-sensing inputs. Once the GTO input of your LC7i detects a speaker-level signal on the Main Inputs, it powers up. When the speaker-level signal goes away, your LC6i will automatically turn-off. Optionally, your LC7i is also equipped with a standard 12-volt trigger (Remote In) that will allow you to turn on your LC7i in the traditional manner.
Sometimes in life (and car audio) we need more outputs than inputs. Therefore we have equipped your LC6i with AutoMode inputs that take the Channel 2 signal and automatically feeds it to the Channel 3 outputs, provided there is no signal present on the Channel 3 inputs. This means your LC7i will accept two input channels and give you four output channels. Or it can accept four input channels and give you six output channels.
12-Volt Output Trigger:
Since you will be using an external amplifier(s) and processor in your system, you will need the ability to "trigger" or turn-on these devices (a romantic dinner won't quite work here). Your LC7i has a high-current 12-volt output (labeled Remote Out) that will provide a trigger to these remote devices, when the LC7i is powered up. Please note that this output is not to be used as the main power for these devices.

Made keeping my factory radio and adding an aftermarket amp install super easy. The accubass works like a charm. I used the 3rd set of output that has accubass on my front door 6x9 to give the a lil kick at low volume

I highly recommend this product to anyone adding on to a factory headunit. You can definitely dial in your sound system and add RCA’s for your highs and bass.
