Pioneer's GM-D7500M mono Class-D amplifier delivers 200 watts x 1 at 4 ohms, or 400 watts x 1 at 2 ohms. That's enough to provide your subwoofer with tight, efficient bass. Speaking of efficiency, the GM-D7500M's Class-D design means less energy is wasted, so you gain more power with a smaller profile. A built-in crossover and bass boost circuit let you dial in the bass content to suit your vehicle.

Pioneer GM Digital Series Amplifiers

A Commanding Performance
Traditional analog amplifier designs are electrically and thermally inefficient--converting as little as 30% of their electrical power into acoustical energy, while the rest is wasted as heat. The dispersion of this excess heat requires large and heavy heatsinks, increasing the size and reducing the installation flexibility of a traditional analog amplifier. Pioneer's GM Digital amplifiers utilize Class-D amplifier technology to produce a compact, high-power amplifier that converts as much as 70% of its input power to sound.

Serious Sound. Small Space.
The compact size of the GM digital amplifiers enables them to be installed in more places in your vehicle. If you want your system to be heard and not seen, Pioneer's GM digital series is the perfect choice, as it's both small and powerful. The advanced circuitry of the GM-7500M model for instance, is 45 percent smaller than its analog counterparts, increasing your installation options in tight spaces. Now you can enjoy superior audio amplification and installation flexibility from a compact product.

Bridge Your System With Digital
The GM Digital line of amplifiers has already earned an impressive reputation with Pioneer retailers and customers alike. This year, for the first time, a full-range solution joins the digital line-up in the form of the GM-D9500F. You can now harness the compact, powerful qualities of digital design to create a full-range, fully digital system.

GM-D7500M Features

Same Powerful Output from a More Compact Amp
100% of the power, 45% of the size--the superior efficiency of a Class-D amplifier means higher power output and greater compactness than an analog amplifier offers.

Efficiently Compact, Awesome Power
Class-D amplifiers overcome the inefficiencies of traditional Class-A or AB amplifiers. Pioneer's Class-D amps transform very little power into heat so a higher percentage of the power supply (67 %) is transformed into the load. This results in a very compact amp which needs less input power to produce very high output power. The Class-D amplifier's PWM (Pulse Width Modulator) modulates the original audio input signal with a triangulated signal wave which has a much higher fixed frequency. The result is a digital signal which contains both the input signal and a band of frequency components around the modulation frequency. A LPF (Low Pass Filter) then filters out the high frequency pulses and the resulting amplified output signal is then sent to the subwoofer and/or speakers.

Selectable 50Hz Bass Boost
Bass boost gives you more control over how your music sounds. It lets you set the optimal bass level for each speaker/sub connected to the GM-D7500M, so the tone controls from your headunit can do what they do best. And because this is selectable bass boost, you can set the level at 0dB, 6dB, or 12dB, whichever sounds best to you.

Built-In Crossover (40~240Hz Low-Pass Filter)
Built into the GM-D7500M is a very smart crossover network. It works like a gateway, routing the big bass signals (adjustable from 40 to 240Hz or lower, at -12dB/octave) and filtering out higher-frequency signals to that subwoofer. This optimizes your system's efficiency and delivers the best possible sound quality.

Speaker Level Inputs
What, you DON'T own a Pioneer head unit? Well, we won't hold it against you. In fact we'll even help you build onto your system. The GM-D7500M's speaker level inputs allow you to connect your OEM unit (or any unit that doesn't have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and you've got a Pioneer amp in your vehicle.

POTENT REMEDY FOR CHEAP CRISP POWER
By F. Khan
I hooked this up in a mazda 3. This is hooked up to a Pioneer w308D4 whose handling is 400w rms at 2ohm and matches perfectly with this Pioneer 9500 amp which is also rated at 400w rms at 2ohms. I keep the volume between 6 and 10 out of 30 so I can keep my hearing and my trunk. This setup is so powerful. The Pros: small size, light weight, current miser, crisp sound. Cons: runs a little warm in an a/c car, cannot stack with other pioneer amps, connectors are unprotected by a shield.

Good amp for the price
By John Scurrah
I have this amp pushing one Pioneer TS-SW2501S4 10-Inch Step Up Shallow S4 Subwoofer and it has no problem doing the job. I have it cranked up and have yet to blow a fuse or cause the amp to shut off.(Not that I'm trying to) I recommend this amp for a modest setup on a budget such as my own.

Little Amp with Clear Big Sound
By James Kotlarz
I have this Amp pushing two Polk DB1040 SVC subs. The Subs are 4 ohms wired in parallel to two ohms. They are rated at 240 rms each and this amp does the job. It is pretty small and light weight but don't let that fool you. It is mounted behind my passenger seat and does not get hot. I ran 8 gauge wire for power and ground and am using the stereo's built in cross-over instead of the amps. I wish the screw holes were not slotted and made of thin plastic. Just try not to over tighten the screws as it could break. I don't notice any difference in sound from hot to cold and have no doubts this amp will provide years of service if installed correctly.
