The GM-DX871 mono subwoofer amplifier can deliver up to 800 watts RMS to your subwoofer, for powerful bass that will give every song a strong and heavy beat. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a small chassis that fits in a lot of out of the way spaces.

  • Big Power-Small Size: Pioneer Class-D amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance.
  • Variable Low-Pass Filter - 40 Hz to 240 Hz.: For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences.
  • Protection Control System (PCS): Pioneer’s PCS continuously monitors the input voltage, current consumption, and operating temperature to automatically adjust the amplifier’s output to ensure operational stability during long listening sessions or when installed in high-temperature environments.

    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.

    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.

    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
