Home » Reviews » Amplifiers » Pioneer GM-D9701 Review – Great Power Output


With 2,400 watts max power, high-quality textured flat panel design, rugged frame and included bass boost remote on board, Pioneer’s GM-D9701 Class D mono amplifier looks and sounds the part.


  • Ridiculous amount of maximum power output in a compact design
  • Versatile installation options
  • One (1)-ohm stable


  • Some owners report overheating when pushed too hard


If your system is in need of raw power, the GM-D9701 won’t disappoint. Depending on how you configure this monoblock amp – that is, what kind of ohm load you present to it based on your speakers – you will have some 2,400 eye-watering max watts to tap into, which is more than enough to temporarily rock the even the power-hungriest of subwoofers.

Even with 500 watts RMS (steady) available at the more common four-ohm load, the Pioneer amp never breaks a sweat…and there’s always the included bass boost remote if you need to turn the slam up even more.

Many electronics enthusiasts won’t give a component – whether it’s one related to mobile audio or home theater – a second look if it isn’t constructed with premium materials, irrespective of how it performs. For these kinds of customers, Pioneer has created its GM Series of amplifiers and the D9701 is a prime example of this attention to detail.

Boasting a high-quality textured flat-panel chassis and a rugged, take-no-prisoners frame, the amp delivers big power in a small size – in fashionable dress.

The amp comes packed with a wired remote bass level control and features a MOSFET power supply, LED power and protect indicators, soft start turn-on, mono channel operation, preamp RCA outputs to daisy-chain multiple amps, three-way protection circuitry, heavy-duty aluminum alloy heat sink, nickel-plated RCA level inputs, nickel-plated screw terminals, variable low-pass filter and more.



Look no further if you are short on install space but crave a ton of current from a mobile audio amp. Pioneer’s GM-D9701 delivers power in spades and is ideal for driving individual subwoofers to their limits, what with its monoblock design and copious amounts of available power.

Depending on the ohm load of the subwoofer you’re using, the D9701 can put out 2,400 watts in a max burst or 500 watts at four (4)-ohms, 800 watts at two (2)-ohms or 1,200 watts at one (1)-ohm RMS. What’s more, to prevent system shutdown, Pioneer’s digital amplifier circuit “Protection Control System” senses its internal temperature and automatically moderates the input level accordingly.

Not only does this stable and durable circuitry reduce the risk of high input power to the unit so it can achieve a 1 ff connection, but the design also provides the flexibility to connect multiple subwoofers to a system.
