Practical features

To simplify setup, a "Maximized" LED indicates when you've set the amplifier's gain for optimum performance. AudioControl's tunable AccuBASS™ circuitry restores and enhances the low-frequency punch in your system, which factory radios often attenuate to protect the stock speakers. An optional wired remote will let you control the bass level from the front seat of your car.

This thing is amazing ...I purchased an Audi SQ5 that needed more bass , installed this in the hidden compartment where the factory amp was located . WARNING ... Audi B&O premium stereo will not activate the remote turn on through speaker signal !! My past history for reference is original Orion hcca's , Phoenix Gold M44, original Rockford Punch, PPI Art series etc.... currently running Polk Digitals in my Rover. This little thing (and it's TINY) is remarkable , have it running a single 10 and couldn't be happier !!! Ease of instal, power output, sound quality, built in x-overs,

Great little amp. Clean power. Graceful turn on so no "pop". Takes my high level in.

Pros: Small. Well built. Good clean power.

Cons: Doesn't have an RJ11 port for remote bass knob like is shown in AudioControls website. This is probably just an older version. No big deal.

Odd, but Excellent

Crutchfield customer from Merced, CA on 8/20/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is very high fidelity for a subwoofer amp, with extremely low noise and distortion specs, and full frequency response if you bypass the filters. It also has very well thought out physical design, with a screw-on heatsink and cover plate to protect your settings, and cable attachments that are secure but detach easily if necessary. It is small, but has a long dimension which didn't allow me to conceal it where I had originally planned. Except for that minor thing, it fits my needs perfectly.

Pros: Small, powerful, quiet, excellent specs.

Cons: None really. It gets a little hotter than I expected, but not alarmingly hot.

Everything you need for a factory sub upgrade in one unit

TC from Westborough, MA on 6/24/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

A small but powerful amp with the added convenience of including AudioControl's speaker-level input, auto turn-on, and Accubass capabilities that used to require you to purchase the separate LC2i unit. This makes the wiring so much easier. The unit is very small so it is easy to find a mounting location. You just run a power and ground wire to it, tap into your speaker level wires (which in my case was a mono subwoofer in a Hyundai Sonata), and then run the new speaker wire from the amp to the subwoofer. After some adjusting, the Accubass does a terrific job of picking a good bass signal out of your factory speaker-level signal. And the auto turn-on works perfectly. Only downside is that it doesn't include the optional "Bass Control" add-on that the LC2i has which allows for controlling the output level from the dashboard. After having the amp installed for a week, that's the one thing I wish I had.

Pros: Small - auto turn-on - Accubass included (no need for LC2i) - speaker level inputs.

Cons: - Instructions were a little light on how to adjust Accubass. Also, the speaker-level output connections were a little small for a high powered amp. Finally, the unit doesn't include the Bass Control option that the LC2i offers.

Amazing features for the price

Victor from Peoria, AZ on 6/14/2018

Great amp with lots of features for the price. I am using as an add on to a stock sound system in an Audi B8 S4. The features, especially the size allows it to fit under the stock amp and out of sight.

Pros: Size and features

Cons: Instructions on tuning accubass and wiring for 2ohm not clear.

Product Research

Features

Overview: This AudioControl ACM-1.300 mono amplifier allows you to add a subwoofer to car stereo system, whether it's a factory system or an aftermarket one. The amp will accept speaker-level or line-level inputs. The ACM-1.300 features a black brushed aluminum chassis, with black powder-coated cast alloy heat sinks and bottom panel in one piece. A black brushed aluminum cover is provided to protect the amp controls from tampering. A small Phillips screwdriver (not supplied) is needed to remove the cover.

Power Output: The ACM-1.300 has the following output:

  • 175 watts RMS x 1 at 4Ω
  • 300 watts RMS x 1 at 2Ω

Subsonic Filter: The AudioControl ACM-1.300 has a full-time 24 Hz subsonic filter. Filtering out super-low frequencies that typically cannot be cleanly reproduced by car speakers saves amplifier power and reduces distortion.

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 raise or lower the level of AccuBASS compensation.

Controls: The ACM-1.300's controls are located under a removable protective panel. A small Phillips screwdriver (not supplied) is needed for removing the panel during setup. A slot-head screwdriver (not included) is needed to adjust the rotary controls. The amp's controls are as follows:

  • GTO Signal Sense: If you are connecting the amplifier to a factory stereo, or an aftermarket unit without preamp outputs and a remote turn-on lead, you can set the GTO Signal Sense to "On" and the amplifier will turn on when an audio signal is detected on the line-level or speaker-level inputs. After a period of time with no signal input, the amp will turn itself off.
  • Low Pass Crossover Frequency: A 3-way switch lets you set the cutoff frequency of the Linkwitz-Riley Low Pass Crossover: 80Hz, Bypass, or 120Hz.
  • Gain: This rotary gain control adjusts the overall output of the amplifier. An LED next to the dial will glow when the gain has been maximized for optimum performance.
  • AccuBASS: The AccuBASS circuit enhances the bass performance of the amplifier.
    • Threshold: The Threshold control selects the level at which the AccuBASS will begin to work.
    • Level: This dial adjusts the level of the AccuBASS.
  • Optional Wired Remote Control: With the addition of an optional wired remote (161ACR1, sold separately), you can easily adjust the output level.

Connections: The ACM-1.300's connections are aligned along the front of the amplifier for ease of installation. The amp's connections include:

  • Fuse: One 30A ATO blade-type fuse is installed in the amplifier.
  • Power: Set-screw terminals are provided for connecting +12V Power, Ground, and Remote In. The set screws can be tightened/loosened with a Phillips-head screwdriver (not included). The Power and Ground terminals will accept up to 8-gauge wire, while the Remote In terminal accepts up to 6-gauge. A 30A fuse should be placed in-line on the power wire, no more than 18" from the battery.
  • Line Level Inputs: One pair of RCA jacks is provided for connecting the amp to the source unit via an RCA cable.
  • Speaker Level Input: One removable Phoenix (or Euroblock) connector is provided for connecting the source unit via speaker-level input. The speaker wires are inserted into the connector and tightened with a screwdriver (5/64" Precision Phillips-head, not supplied).
  • Speaker Output: A removable Phoenix connector is provided for connecting speaker wire up to 12 gauge. The amplifier will accept a load impedance of 2Ω or higher. The speaker wires (for 2 speakers) can be inserted into the connector and tightened with a screwdriver (9/64" Precision Phillips-head, not supplied).
  • RJ-14 Jack: The RJ-14 jack is used to connect an optional wired remote (161ACR1, sold separately).
