Overview

Our take on the AudioControl LCQ-1

AudioControl's LCQ1 6-channel line output converter (LOC) with 11-band equalization and bass restoration allows you to add aftermarket amps, speakers, and subs to your car's factory radio, so you can enjoy better and more powerful sound without losing climate controls, voice-activated functions, or other built-in factory features. The LCQ1 accepts speaker-level signals, so you can use it with just about any setup, even high-powered amplified systems.

Add amps and fine tuning to your factory system

AudioControl's LCQ1 6-channel line output converter (LOC) with 11-band equalization and bass restoration allows you to add aftermarket amps, speakers, and subs to your car's factory radio, so you can enjoy better and more powerful sound without losing climate controls, voice-activated functions, or other built-in factory features. The LCQ1 accepts speaker-level signals, so you can use it with just about any setup, even high-powered amplified systems.

Summing

The LCQ1 sums its input signals together, even if they've been crossed over for tweeters, mids, and subs by the factory system. That way, you can count on a strong, smooth, full-range signal for your processors and amps. The LCQ1 features six RCA preamp outputs that'll handle a traditional front/rear/sub setup.

Equalization

The LCQ1's graphic equalizer will help make your music sound fantastic in your car, utilizing 11 bands of adjustment for sonic fine tuning. Most car audio problems occur in the bass frequencies, so this processor's subwoofer channel gives you five bands of equalization between 31.5 and 100 Hz. The front and rear channels each feature six bands of equalization at varying intervals from 125 Hz up to 8,000 Hz.

Why you have to restore the bass

Many factory radios actually turn the bass down as you increase the volume to protect the cheap factory speakers, subsequently removing much of your music's power and punch. AudioControl developed a patent pending AccuBASS™ circuit that restores the bass the factory radio erased, giving you much fuller and more enjoyable sound. The AccuBASS is applied to the subwoofer output channel, so your sub amp can have the entire, restored signal to work with.

Level-matching with an LED indicator

AudioControl makes it easy: set your factory stereo to about 3/4 maximum volume, turn the output level control of the LCQ1 until the "Maximized" light begins to flicker, then adjust the gain controls on your amps and you're done. You've level-matched the output of your receiver to the amplifier's input, so you can count on getting maximum performance and minimum noise from your system.

Convenience

The optional dash-mounted ACR-2 wired remote allows you to adjust the volume of the bass while you're on the go, and to bypass and reengage the EQ to demonstrate your fine tuning. The speaker-level inputs sense incoming signals and turn on the LCQ1, while a built-in 12-volt trigger turns on your amps as well. If your factory system only has channels for front and rear speakers, AutoMode™ will create the output you can use for your subs.

Night and Day with the sound quality since I've installed the Audio Control LCQ-1. When using a factory radio its basically HEAVEN.

Features

Overview: The AudioControl LCQ-1 is a powerful six-channel signal processor that provides a gateway between factory installed source units and aftermarket amplifiers. It is a compact, six-channel, high-performance, OEM line-output converter with independent multichannel equalizers to custom tune your car audio system. The LCQ-1 allows you to easily "tune" your audio system & receive improved sound quality. An ideal combination of discrete equalization controls combined with AudioControl's unique OEM integration circuitry, the LCQ-1 maximizes the performance of factory installed audio systems. No longer will you have to compromise when performing basic amplifier additions to a factory installed audio system. The active circuitry used in the LCQ-1 provides dramatically better sound quality & enhances the bass response.

AccuBASS: Designed for maximum sound quality and enhanced audio performance, the LCQ-1 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. Factory installed amplifiers and woofers are (unfortunately) not designed to reproduce bass at high volumes. Car manufacturers adapt to this by taking the bass out of the signal when you turn up the volume. AudioControl developed the patent pending AccuBASS circuit to restore bass. After a quick and easy one-time setting, the AccuBASS circuit takes over the bass just as the factory system rolls off. You get smooth, seamless, and rock solid bass response regardless of volume level.

Individual Equalization Controls: To custom tune your system, the LCQ-1 gives you dedicated equalization controls for the Front, Rear, & Subwoofer outputs.

Channel Type Equalization Frequencies Level Adjustment
Front  125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 8kHz -12 to +12 dB
Rear  125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 8kHz -12 to +12 dB
Subwoofer 31.5Hz, 50Hz, 63Hz, 80Hz, 1000Hz -12 to +12 dB

6ch Speaker Level Inputs: The LCQ-1 has active, high-voltage, high-impedance (20K Ohms) speaker-level inputs that accepts signals from high power, factory installed amplifiers (up to 400 watts per channel). This means the AudioControl LCQ-1 will work with factory-installed audio systems and give you a higher-quality signal with lower noise, lower distortion, and higher output voltage. These inputs get their signals from the speaker-level outputs of your factory installed source unit or amplifier. If your source unit has front, rear, & subwoofer speaker-level outputs, connect them to the three sets of inputs on your LCQ-1.

AutoMode Input: If the source unit only has front & rear outputs, the Auto Mode circuitry in your LCQ-1 automatically routes the Channel 2 input channels to the (Channel 3) subwoofer channels.

Internal Channel Summing: The LCQ-1 employs internal channel summing for interfacing with factory installed amplifiers with built-in crossovers.  Channel summing lets you eliminate any factory-installed active crossovers. Many of today's factory stereo systems include separately amplified & crossed-over tweeters, midranges, & subs. If you are going to add aftermarket amps and speakers to the car you will need to combine (or sum) these separate signals into a single full-range signal for the new system. The LCQ-1 has the capability to combine together multiple (2, 4, or 6) input signals from the factory source unit into 2 channels. The LCQ-1 has internal jumpers that allow you to select which input signals will be summed into the Main outputs. When the jumper is moved to the "Sum" position, there will also be a corresponding green indicator light on the front of the LCQ-1.

Note: The LCQ-1 is shipped from the factory in the non-summed (separate) position.

Preamp Outputs: The AudioControl LCQ-1 is equipped with 3 stereo preamp outputs (Front/Main, Rear/Ch2, and Sub/Ch3) to connect to your aftermarket amplifier(s). Each stereo preamp output has an independent level control which allows you adjust the signal level from your factory source unit to match the input of your aftermarket amplifier(s).

GTO (Great Turn-On) Circuit: The main speaker level inputs have a signal sensing circuit (GTO) that turns the unit "On" when there's a speaker level input signal, and turns the unit off when the signal disappears.

Remote Output: The +12 volt DC remote output will trigger an amp to turn on whenever the LCQ-1 is "On". The remote's maximum current output is 1 amp.

Optional Remote Control: You can add a multi-function dash control (161ACR2, sold separately) that allows you to set the level of the subwoofer. It also has an in/out switch for the equalizer function so you can hear the system before and after your tuning changes. The ACR-2 is a multi-function remote that gives you control over the level of the Channel 3/Subwoofer output so you can balance the bass level with the rest of the system. An additional feature of the ACR-2 dash remote is that it allows the equalization to be switched in and out of the audio circuit by tapping the switch. You can hear the system before and after the EQ adjustments.

Installation: The LCQ-1 needs to be installed in the signal path between your OEM source unit (or factory amplifier) and aftermarket amplifier(s) and/or processor(s). Do not connect the LCQ-1 between the factory head unit and the factory amplifier. Locate the amplified speaker wires that are coming from your factory source unit and/or amplifier and connect them to the speaker-level inputs on the LCQ-1. In many cases you can find factory speaker leads in the rear of the vehicle or at the factory amplifier. Then use RCA connecting cables to connect the RCA outputs of the LCQ-1 to your aftermarket amplifier(s). Finally, connect +12V power and ground. The LCQ-1 has a 12-volt trigger input, but normally you will just let the GTO turn on circuit take care of that by itself.

Crutchfield asked  
Why did you buy this?

I chose this product because I'm adding my system from my other car that had an aftermarket cd player. My newer vehicle would need a $200 dash kit and I'd lose a lot of the functions in my car like xm receiver and climate controls. I'm using the LCQ-1 to add my Rockford 1500.1 channel amp and a 100.4 channel amp for my 2 15" FI car audio BL subs and component speakers. From my research, this will work out perfectly, not to mention the EQ is an added bonus as my stock radio only offers L, M, H eq [ D  Feb 11, 2016 ]

8 questions already asked

Tap the speaker wires after the amp. [ Mike  Mar 18, 2017 ]
I'm not 100% sure about the answer I'm going to give. I would think if you are going to use a completely different amp I would think you would need to tap into the wires coming from the head unit to send the signal to the LCQ-1 and from there to your new amp. Hope this helped you. You may want to talk to one of the crutchfeild techs to be 100% though. Or maybe try to research on you-tube. [ JUSTIN  Mar 17, 2017 ]
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Jeff  Jan 19, 2014 ]  Staff
Thanks [ Chet  Jan 14, 2014 ]
What do I need to connect a Sony CDX-M60ui receiver to a MB Quartz NA540.6 Amp? Thank you, [ Chet  Jan 14, 2014 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Jeff  Dec 27, 2013 ]  Staff
It sure will. Keep in mind that your getting an equalizer as well and the bass feature. I recommend getting the bass adjustable control as well. With out it you won't be able to use the EQ. Unless your a techi like me and get a phone line jack and splice the wires to create a loop. [ ELBERT  Jan 30, 2017 ]
It will help clean up the sound so you get the most out of the speakers. Especially in vehicles where you can't make too many adjustments through the head unit. It helped make my mids and rear speakers sound better cause I could cut back frequencies that didn't sound right to me. Gave my sub amp a better signal but not necessarily that much louder.
