Cool power

Pioneer's sharp-looking GM-D9601 mono amplifier can send up to 1200 watts RMS to your sub setup, for powerful bass that'll get you and your car rockin'. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a compact chassis that fits in a lot of out-of-the-way spaces. And this little workhorse can handle a 1-ohm load without breaking a sweat, so you never have to worry about impedance matching when you add subs to your system down the road.

Connecting and tuning made simple

If your car stereo doesn't have RCA outputs, you can use the speaker-level inputs to hook this amp into your system  — the amplifier switches its input mode automatically when it detects the high-level signal. The amp's got a low-pass filter that lets you quickly sharpen and focus the bass to suit your car's interior, and also includes a wired remote boost that lets you control the bass from the front seat.

Putting together a bass system with this amp? Check out this Crutchfield-approved amp/sub package.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Crutchfield Customer Review (What's this?)

Decent but ihow is a mono amp 2 channel?

Pros: Sleek and powerful works like a charm and can pump some serious power.

Cons: Mono amp that is 2 channel doesn't make much sense to me and I can't find any literature saying if bridging will increase power or work at all. Don't want to risk my system to find out.

Crutchfield Customer Review (What's this?)

Can't beat Pioneer's quality. Using 4 gauge power/ground wire is a necessity even going for full output. Running 4 Pioneer 10" subs at 4 ohms, Sounds great, no problems most of the time, Bass heavy music "can" shut the amp off if gains and bass boost are not properly set. Built in safety feature will cut the amps power if it pulls to much current. Class D amp, so no heat problems, even with extended play. Overall, this amplifier is great value and quality.

Pros: -1 ohm stability -Power -Sound -Quality

Cons: -No 0 gauge inputs

  • Ease of Use
  • Sound Quality
  • Value

Just got the Pioneer GM-D9601 and hooked it up to a Pioneer TS-W3002D2 sub at a 1 ohm load since its 1ohm stable and its rocking hard. Nice sound, deep bass but i cant figure out why the bass. at times. cuts off.....maybe too much power. Overall i would recommend it to anyone.

Pros: looks output

Cons: Bass cuts off at times. Maybe its just the way i have it hooked up (user error)

Product Research



CEA 2006 Compliant: The Pioneer GM-D9601 mono subwoofer amplifier power ratings are measured according to the Consumer Electronics Association's CEA-2006 standards. These standards allow you to accurately compare the rated power output of all CEA-2006 compliant amplifiers, even from different brands. Manufacturers who adhere to the standards can display the CEA-2006 logo on their products and packaging. CEA-2006 Specifications:

  • Power Output:
    • 500 watts x 1 at 4Ω with <1% THD+N
    • 800 watts x 1 at 2Ω with <1% THD+N
    • 1,200 watts x 1 at 1Ω with <1% THD+N
  • Signal to Noise Ratio: 75 dBA

1Ω Stable: The GM-D9601 is capable of powering load impedances down to 1Ω.

Auto Turn-on: When using a high voltage speaker level input, a signal sensing circuit will automatically turn the amp on and off along with the source unit.


Gain Control: The gain control is continuously variable from 200 mV to 6.5 V.

Crossover: The low pass crossover is always engaged, and is continuously variable from 40 to 240 Hz.

Bass Boost: The bass boost circuit is variable from 0 to +18 dB, centered at 50 Hz. Adjustment is made using the included wired remote.

Wired Remote: The bass boost circuit is controlled using the included wired remote, which can be mounted within easy reach of the driver. The remote has integral flanges on both sides to mount the unit under the dash. The remote measures:

  • Width: 1.73" (2.63" including mounting tabs)
  • Height: 0.75"
  • Depth: 1.62" (2.2" including control knob and cable)


Power: The power and ground connections are set screw terminals that will accommodate up to 4-gauge wire. The included 3mm Allen wrench is used to tighten and loosen the terminals. Pioneer recommends different power and ground wire gauges based on the length of the wire:

  • 6-Gauge: up to 11' 10"
  • 4-Gauge: up to 21'

Remote Turn-on: The remote connection is a set screw terminal that will accommodate up to 8-gauge wire. The included 3mm Allen wrench is used to tighten and loosen the terminals.

Speaker Connections: There are two pair of speaker output set screw terminals, internally shorted together so it's easy to connect two subwoofers. The terminals will accommodate up to 8-gauge wire. The included 3mm Allen wrench is used to tighten and loosen the terminals.

Signal Input: The amplifier features one pair of stereo RCA inputs. If no line level signal is available, use the included speaker wire to RCA adapters.

RCA Output: One pair of preamp output jacks provide a convenient way to daisy-chain an additional amplifier without running another set of RCA cables from the front of the vehicle to the amplifier location. The output is not affected by the internal crossover.
