About the AudioControl ACX-300.4

Waterproof power

One of the main issues with powersports amplifiers used to be that the amp wouldn't survive a thorough washing of your vehicle after a good day of dirty fun. AudioControl's ACX-300.4 four-channel 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 music loud and clear

The ACX-300.4 can send out 50 watts RMS per channel — plenty enough to hear your music clearly over the sounds of wind and motor. Like it loud? This amp can also operate in two-channel mode to power a pair of high-performance speakers with 150 watts RMS each.

Some practical features

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" LEDs indicate when you've set the amplifier's gains for optimum performance.

Product Research

Features

Overview: The AudioControl ACX-300.4 all-weather amplifier is a compact 4 channel amp designed for your boat, ATV, UTV, motorcycle, and more. The all-weather amp can provide 50 watts RMS into a 4Ω load, 75 watts RMS into a 2Ω load, and 150 watts bridged into a 4Ω load. The ACX-300.4 also features both RCA line-level and speaker-level inputs, making it ideal for OEM and aftermarket headunits.

Note: The AudioControl ACX-300.4 does not include an amplifier wiring kit. A minimum 8ga. kit is recommended (sold separately).

High-/Low-Level Inputs: The ACX-300.4 includes four 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

Input Mode: A 2-way switch lets you select whether one pair or both pairs of input channels will be used to feed all four output channels.

Crossovers: The ACX-300.4 includes two 12 dB/octave Linkwitz-Riley high-pass filters, one for Channels 1 & 2 and one for Channels 3 & 4. Both use a 3-position switch to change the crossover point with a choice of  80Hz, 120Hz, or Bypass.

Gain Maximized LEDs: Each pair of channels on the amp includes its own Gain control to properly set the overall output level. A Maximized LED indicator is provided for each pair of channels, illuminating 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.

All-Weather Construction: The ACX-300.4 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: Four RCA jacks on 12" input cables are provided, each with protective plastic caps.
  • Speaker Outputs: Two 12" 4-wire output harnesses are terminated in waterproof connectors. Matching 7" harnesses with bare-ended 18ga. wires are included.
  • 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-300.4 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.

Specifications:

  • Preamp/Speaker-Level Inputs: 4 (RCA)
  • Preamp-Level Voltage Range: 500mV - 6Vrms
