Features

Marine Amplifier: The Wet Sounds Hydro-Tech X (HTX) series amplifiers are equipped with conformal coated PCBs, and are specifically designed for marine applications. In addition, the amp features completely sealed, salt-water compliant, high mass heat sinks and stainless steel hardware that resists corrosion.

Extended Side Panels: The amplifier's side panels extend approximately 1/2" below the bottom of the amplifier chassis. This allows air to circulate under the amp for cooling purposes. It also allows you to hide the wiring under the chassis.

Logo: The Wet Sounds logo is mounted over the dual-illumination status LED on the top of the amp. The LED light shows around the edges of the logo to let you observe the amp's status. When the amplifier goes into protection mode, the LED light will flash a red diagnostic sequence to aid you in troubleshooting.

Control Panel: The control panel is protected by a cover to help keep the controls dry, and to prevent unwanted adjustments. The cover screws can be removed with the supplied 2.5mm Allen wrench. These rotary controls require the use of a flat-head screwdriver (not supplied) to make adjustments. Except for the Input Mode switch, this 4-channel amplifier features independent controls for the front (CH1+2) and rear (CH3+4). The controls includes:

  • Input Mode: The Input Mode switch determines the input source of the rear channels (CH3+4). In the 2CH position, the front and rear channels receive the input signal from the Channel 1 and Channel 2 RCA inputs. In this position, you will not have fading capabilities between the front and rear outputs. In the 4CH position, the front and rear channels each have separate input signals, and fading between the front and rear outputs is possible.
  • Input Gain: The Input Gain control lets you match the amplifier to the source unit. The input sensitivity of the amp ranges from 0.2V to 6.1V.
  • Crossover Frequency: The amplifier's built-in Crossover is continuously variable from 50 Hz to 250 Hz, and has a slope of 12dB/octave.
  • Crossover Switch: The Crossover Switch lets you set the built-in crossover to high-pass or low-pass operation. There is no Full Range position.

Connections: The HTX-4's wiring connections are on the front of the amplifier, and are protected by the removable top panel. The connections are as follows:

  • Power/Ground/Turn-on: The amplifier has set screw terminals for the power, ground, and remote turn on. These connections require a Phillips-head screwdriver (not supplied) to tighten/loosen the set screws. The power and ground terminals will accept up to 4 AWG wire, while the remote turn-on terminal will take up to 6 AWG.
  • Fuses: The amplifier is protected by two 25-amp ATO blade-type fuses.
  • Preamp Inputs: Two pairs of RCA inputs (CH1+2 and CH3+4) are provided for connecting the input signal from the source unit.
  • Speaker: The speaker output has two removable connectors (front + rear) with captive C-clamp terminals. These C-clamps will accept 12 AWG to 16 AWG speaker wire, and require a small flat-head or Phillips-head screwdriver (not included) to tighten/loosen the clamps.

Q
What is the output at 12.5 volts?
[ Chad  Aug 06, 2018 ]
1 answer
A
I'm afraid that information is not provided. Wet Sounds uses CEA-2006 criteria to rate the power output on the HTX-4 amplifier, and the criteria for measuring power uses a DC input voltage of 14.4 volts. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat.
