About the AudioControl ACX-300.1

Waterproof power
Waterproof power
One of the main issues with powersports amplifiers used to be that the amp wouldn't survive when you washed off your vehicle after a good day of dirty fun. AudioControl's ACX-300.1 mono subwoofer amplifier carries an IPX6 waterproof rating, which means you can clean it off with a powerful water jet spray and it won't hurt a thing. Construction details include conformal circuit board coatings, insulated gaskets for the control panel cover, and waterproof input, output, and power connections.
Play your bass loud and clear
The ACX-300.1 can send out up to 300 watts RMS to your sub — plenty enough to hear the bass clearly over the sounds of wind and motor. This tiny, hand-size amp will fit almost anywhere in almost any kind of vehicle, and it features high-level inputs with signal-sensing turn-on, so it'll work with almost any stereo system. To simplify setup, a "Maximized" LED indicates when you've set the amplifier's gain for optimum performance.

Product Research
Features
Overview: The AudioControl ACX-300.1 all-weather amplifier is a compact mono amp designed for your boat, ATV, UTV, motorcycle, and more. The all-weather amp can provide 175 watts RMS into a 4Ω load and 300 watts RMS into a 2Ω load. The ACX-300.1 also features both RCA line-level and speaker-level inputs, making it ideal for OEM and aftermarket headunits.
Note: The AudioControl ACX-300.1 does not include an amplifier wiring kit. A minimum 8 ga. kit is recommended (sold separately).
High-/Low-Level Inputs: The ACX-300.1 includes two built-in 12" RCA inputs that can accept either high- or low-level input signals. If running high-level signals, RCA to speaker-wire adapters must be used (sold separately), or the RCA connectors must be cut off and the bare-ended wire used.
- Low-Level Input Range: 500mV - 6Vrms
- High-Level Input Range: 1Vrms - 12Vrms
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, and a Level control that adjusts the amount of AccuBASS compensation.
Crossovers: The ACX-300.1 includes a 12 dB/octave Linkwitz-Riley low-pass filter with a 3-position switch to change the crossover point. Choices include 80Hz, 120Hz, or Bypass.
Gain Maximized LEDs: The mono amp's inputs include a Gain control to the properly set the overall output level. A Maximized LED indicator will light to let you know when the output signal has reached its optimum performance level, helping to avoid running a distorted signal to your speakers.
GTO (Great Turn On) 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, 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.
Optional Wired Remote Control: The ACX-300.1 amplifier features a female 3.5mm jack on a built-in 12" harness, letting you connect an optional ACR-1 wired remote control (sold separately). A 16.5' ACR-1 connection cable is provided, with a male 3.5mm connector on one end and an RJ-14 connector on the other end, that connects to the wired controller.
All-Weather Construction: The ACX-300.1 amp has been constructed to withstand outdoor environments and carries an IPX6 waterproof rating, making it impervious to weather. A removable cover-plate on top of the amp protects the controls and LED indicators from dust and moisture ingress. The cover-plate screws require a 2.5mm hex bit for removal (not included). All wire harnesses on the amp are built-in for added weather resistance:
- Audio Inputs: Two RCA jacks on 12" input cables are provided, each with protective plastic caps.
- Speaker Output: A 12" 2-pin speaker-wire output is terminated in a waterproof connector, and includes a matching 7" harness with bare-ended wire.
- Power/Ground/Remote: A 12" section of 10ga. power and ground wire terminates in a waterproof connector, with matching 7" harness and bare-ended wire. An additional empty power/ground connector is provided, letting you build your own harness to match the amp's power/ground connector. A bare-ended 12", 18ga. remote turn-on wire is provided in the power/ground harness.
Mounting: The AudioControl ACX-300.1 features built-in mounting flanges on either end of the amp, with two pre-drilled holes in each, allowing the amp to be mounted in a variety of locations. Four 3/4" screws are provided for mounting.
