Power galore

Two keys to unlocking great sound in a car stereo system are serious power and extensive control — and this amp's got them both. For power, AudioControl's LC-1.800 mono subwoofer amp puts out up to 800 watts RMS, so it'll make your subwoofers happy. The adjustable low-pass and fixed subsonic filters make sure your sub gets only the frequencies it was designed to play, while AudioControl's AccuBASS® circuit ensures that your bass sounds great.

Active controls

Most factory radios turn down the lower frequencies as you turn the volume up in order to minimize stress on inexpensive factory speakers. AccuBASS eliminates this bass rolloff, so you get maximum bass performance when you add aftermarket amps to a factory radio. Onboard LEDs indicate optimized signal flow for inputs and outputs, plus give you a warning when a source is too loud and causing distortion. An optional wired remote lets you control bass volume from the front seat.

Works in almost any system

AudioControl designed the LC-1.800 to work equally well with aftermarket and factory stereos. Speaker-level inputs allow you to connect to almost any factory radio. Signal sensing circuitry turns the amp on via the speaker-level inputs, so you won't need to run a remote turn-on wire throughout your vehicle.

I paired this amplifier With audio control's d 4.800 and hertz speakers it sounds amazing. Audio Control have always made good Quality products plus they stand behind what they make and with a 5 year warranty. You can't beat that try them your ears will thank you.

Pros: 5 year warranty a company that will stand behind their product

Cons: None

Great amp, non defeatable filters though.

David from Everett, WA on 11/27/2018

Great performing amp and good price however, the crossover cannot be defeated, only adjusted. To use a separate DSP, the crossover needs to be set at the highest frequency frequency to allow the dsp to cross it lower and be out of the way for example, I cross at 80hz but not in the amp, I set the amp to the highest frequency as a workaround but I'd rather it was defeatable. If mounting vertically and right side up with the nomenclature properly readable, there is a gap in the heastink area that will allow screws and other garbage in. If mounting vertically I would mount them 90 degrees right or left so the heatsink is facing either right or left. The cover is supposed to keep garbage out of the controls but no thought about the huge point of entry I mentioned earlier. The other thing few manufacturers mention is that when setting up two of these for stereo bass, one amp for each of two subs, you must use an RCA Y cable or the output will be weak from only sending one input to the left and right summing circuit. So far JL Audio makes this clear, nothing from Audio Control, not a word. I'm past my return window or I'd get the JL Audio HD series. This LC-1800 is such a good amp marred by some very easily correctable shortcomings in how the design was executed. If none of what I mentioned matter to you, eg, you will use the amp's crossover and not mount it vertically with the fins up, you can not get more amp quality for the money. I never used the Accubass,

Pros: Very decent amp and compact, a tremendous value for sound quality at this price.

Cons: Crossover is non-defeatable, has to be worked around using a separate DSP or the head unit's crossover and dsp. If mounting vertically with the heat sinks facing up, there is a huge gap that things can fall into the amp such as crews etc.

Product Research

Features

Overview: The AudioControl LC-1.800 mono subwoofer amplifier is designed to enhance the sound of your car stereo system, whether it's a factory or an aftermarket one. Outputting 500 watts @ 4 ohms and 800 watts @ 2 ohms, the LC-1.800 can accept both line and speaker level inputs. Key features include AudioControl's AccuBass compensation circuit, GTO signal sensing turn-on, and a connection port for the optional ACR-1 remote level control (sold separately).  The amplifier features a black brushed aluminum chassis, with black powder-coated cast alloy heat sinks and a one piece bottom panel. A black brushed aluminum cover is provided to protect the amp controls from tampering. The included 2.5mm Allen key is used to remove the cover.

AccuBASS: The patented AccuBASS processing circuit compensates for factory bass rolloff to improve bass performance, especially with most factory installed sound systems. The circuit has two rotary controls: the Threshold lets you dial in the level at which the AccuBASS will begin to work, while the Level control raises or lowers the level of AccuBASS compensation. A slide switch allows the AccuBass feature to quickly be Enabled or Disabled.

ACR-1 Remote: The optional AudioControl ACR-1 wired remote lets you adjust the subwoofer output level from the driver's seat. The remote level control comes with a 20' cable, terminating in an RJ-14 jack that plugs into the amp, and is designed to be mounted under a dash for easy access while driving.

Maximum Input Level Control (MILC): The amplifier analyzes the input signal to detect any clipping. If the signal reaches the level of clipping, the MILC Source Clip LED glows red, prompting you to turn down the gain level. When the gain level is maximized, a green Maximized LED will glow to indicate the gain, for that set of channels, is set to the optimum level.

GTO (Great Turn On) Signal Sense: If you are connecting the amplifier to a factory stereo or an aftermarket unit without a remote turn-on lead, the GTO Signal Sense circuitry can turn on the amplifier when an audio signal is detected on either the line-level or speaker-level inputs. After a period of time with no signal input, the amp will turn itself off. An On/Off slide-switch is provided on the amp activate the GTO Signal Sense feature.

Controls: The LC-1.8200's controls are located under a protective panel that can easily be removed with the included 2.5mm Allen key. A flat-head screwdriver (not included) is needed to adjust the rotary controls which include the AccuBass and GTO settings, a Low-Pass crossover with a range from 30 Hz to 230 Hz, a Polarity switch with 0 or 180, and LED indicators for Power and Protection.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
102db SNR, +600 damping, high current, made by people who really enjoy "music". Need all the bass guitar notes in my life.... [ chris  Aug 14, 2018 ]
A
Combining with Audiocontrols D 4.800. I purchased this primarily because it has the same footprint as the D4.800 and the 800W at 2 ohm power rating. [ Jerry  May 19, 2018 ]
A
I thought it would work well with the lc7 signal processor and he matched the rms value for the Jk stealth box. [ Mark  Apr 07, 2018 ]

Q
CAN YOU SUM A FACTORY SPEAKER AND FACTORY SUBWOOFER SIGNAL FOR THE HI LEVEL OR JUST DO BOTH SPEAKERS?
[ Melissa  May 29, 2018 ]
1 answer
A
From what I can tell this unit does not sum multiple channels as its designed for a subwoofer application. It only has 2 channel input, L/R. With the crossover you can feed it a full range signal if necessary.
[ Aaron  May 30, 2018 ]
Q
Does this amp have a built in fan?
[ Ga  Feb 11, 2018 ]

Q
Why would I need a wired subwoofer remote?
[ Mike  Jan 19, 2018 ]
1 answer
A
Its used to adjust the level of the bass without having to go the amp to do it for individuals that like to boost the bass for some songs but turn down the bass on other songs. HTH! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101
