About this item

  • Power - 1100 Max x 1 @ 2 Ohms, 550 Max x 1 @ 4 Ohms
  • Class A/B Topology - Class ‘A’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class ‘B’ amplifiers have no current flowing through its outputs with no audio signal
  • Mosfet Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
  • Low & High Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
  • Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction
  • Switchable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
  • Variable Input Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier

MOSFET Power Supply

Class A/B

2 Ohm Stable

High and Low Level Inputs

MOSFET Power Supply

Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high-efficiency output.

Class A/B

Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency.

2 Ohm Stable

2-Ohm stable comfortably powers speakers or subwoofers when in use at 2-Ohms, resulting in more power and volume.

High and Low Level Inputs

High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units.

Fixed Low Pass Filter

Switchable Bass Boost

Short Protection

Variable Gain Control

Variable Low Pass Filter

Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.

Switchable Bass Boost

Switchable Bass Boost allows you to boost the low bass +18db.

Short Protection

Automatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short.

Variable Gain Control

The Variable Input Control allows the amplifier input to match the output signal from the head unit to achieve optimum performance when adjusted properly.

    5.0 out of 5 stars Great upgrade for Focus with the Sony system
    Reviewed in the United States on April 18, 2023
    Was relatively simple to wire up. I piggybacked it off the factory Sony amp, using the violet/red +12V in wire for battery power and connecting the remote-on trigger wire to the brown/green wire going into the nearby trunk light. Ground went to the driver side rear seatbelt anchor point under the cushion, which just pulls straight up and out of the way for easy access. It’s a Torx T-50 bolt. Wired the High Input harness to the rear speaker out wires coming from the factory Sony amp module. Works like a charm.

    I originally installed this amp using the factory subwoofer (just one of the 2-ohm voice coils, not using the other), and it was leaps and bounds from how it sounded with the stock amp. It was so badly underpowered from the factory. However, the tiny stock sub still fails to cleanly reproduce anything under 40Hz without being overpowered by the amp. I solved this by installing an NVX custom 10” sub (found on Amazon as well) and now the system sounds amazing, just how I would have hoped a premium Sony system would right off the bat. Very deep and clean bass, punchy and very tunable with the adjustment knobs. I didn’t use the remote amp level knob, but I have the amp tuned just where I like it with the head unit “Bass” level at 50%, so I have some adjustment through the factory stereo. Great amp.

    I can’t find anything I dislike about this amp. Puts plenty of power out for what I need. Lights up blue when it’s working! It’s affordable and gets the job done, the bass controller is a nice addition! I paired it with this cheap 10” sub and it’s perfect
