Our take on the Jensen XA2125

Jensen

Jensen amplifiers sport a redesigned look, but these impressive performers are still as affordable as ever!

The XA Series XA2125 amplifier pumps out a potent 125 watts RMS per channel, with an ultra-quick MOSFET power supply for cool-running, reliable performance. Top-mounted controls give you quick access to the high- and low-pass variable crossovers that let you adjust the exact frequencies you send to your speakers. Dial in the variable bass boost (0-12 dB at 45 Hz) for some bump in your thump.

Details:
  • stereo, bridged mono or Tri-way output
  • 125 watts RMS x 2 at 4 ohms
  • 175 watts x 2 at 2 ohms
  • 350 watts x 1 in bridged mode
  • requires 8-gauge power and ground leads — wiring and hardware not included with amplifier
  • MOSFET power supply
  • speaker-level inputs
  • selectable 40-400 Hz variable high- and low-pass crossovers, 12 dB/octave
  • 0-12 dB variable bass boost at 45 Hz

Features

Top-Mounted Controls: The XA2125 amplifier features convenient, top-mounted controls for quick access.

Internal Crossovers: The internal crossover is a 12dB/octave filter selectable for high-pass, full- range, or low-pass operation. Each channel has a separate control that allows you to independently adjust the crossover frequency from 40Hz to 400Hz.

Bass Boost: The amplifier includes a control that allows you to boost bass from 0 to +12dB, centered at 45Hz.

Remote Gain Control: The remote gain control knob can be mounted in the front of the vehicle and is wired to the amp via the included cable (with phone type jacks at both ends). The remote control is 1.008" tall, 2.542" wide, and 1.748" deep (2.092" including the knob).

RCA Preamp Outputs: The gold-plated preamp output jacks provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location. These RCA jacks output a full-range signal.

Protection Circuitry: Thermal, short circuit, low impedance, and DC offset circuits are used to help protect the amplifier from damage and ensure reliable operation.

Controls

Top of Amplifier:

  • Crossover Switch: allows you to select high-pass, full-range, or low-pass crossover operation
  • Left Channel Frequency: variable from 40Hz to 400Hz
