Features
  • Turn Up the Bass

    This amplifier features a wired bass control remote for optimal bass level adjustment according to your listening preferences and the characteristics of the music.

  • Big Power-Small Size

    Pioneer’s extra-efficient Class-D amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than a typical Class AB amplifiers. That makes them more versatile in terms of installation as well as performance.

  • Packs a Punch

    This mono amplifier is rated at a total of 1600 watts (max power) with high-current circuitry that provides all the power you need, delivering 300 watts RMS at 4 ohms, 500 watts RMS at 2 ohms, and up to 800 watts RMS at 1 ohm.

  • Auto Signal sensing and Turn-On

    When used with an audio source such as an OEM source or a receiver without RCA output, the amplifier will activate as soon as an audio source is detected through the speaker level outputs.

  • High-Quality Affordable Design

    Pioneer designed a high-quality power supply to sustain constant power requirements.

  • Gold Plated Terminals

    These terminals maintain an accurate signal with increased electrical conductivity, prevent corrosion, and offer enhanced durability with excellent resistance to wear.

  • Pioneer’s TVC (Total Vibration Control)

    Pioneer's TVC (Total Vibration Control) concept used in this amplifier not only increases the rigidity of the unit but also counteracts vibrations that affect sound quality at various points.

  • Protection Control System (PCS)

    Pioneer’s PCS continuously monitors the input voltage, current consumption, and operating temperature to automatically adjust the amplifier’s output, ensuring operational stability during long listening sessions or when installed in high-temperature environments.

    The amplifier features a variable low-pass filter (LPF) ranging from 10 Hz to 240 Hz, allowing precise adjustment of the audio bandwidth to optimize the acoustic performance of your subwoofer.

    Bestbuy.com Please check carefully what they sell,

    I had to make a second purchase of an amplifier since the first one I bought needed parts and fuses, which disappointed me and I bought this option of open box excellent condition, unfortunately the same thing happened with this one, thanks to the chat assistance I had to go to a Besbuy store to give me the fan parts, for now it works well but they must certify well what they sell, since this AM was not in excellent condition and missing parts.

    You will get your moneys worth and more

    Best amp I ever had. I currently have it hooked up to 3 10inch dual 2ohm kickers wired at 1.3 ohms and its absolutely too much for my vehicle Im now forced to upgrade the rest of my audio to match but my favorite part is how after a nine hour trip it wasn't very hot the quality doesn't meets the price its way lower priced than other quality amps like alpine

    Gives all you want for the price! Well done!

    Didn't see it on the shelf, but one of the store salesmen stepped in and provided some help. I bought this for a Kicker Comp VR, 2 ohm dual voice coil. I wired the 12 for 1 ohm and let me tell you, this amp HITS! The gain is only set for 1/4 up and I am blown away, literally. Thank you for help.
