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.

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.

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).
