The Pioneer GM-DX874 four-channel amplifier will deliver up to 150 watts RMS to each of your front and rear speakers for powerful music. 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. The frequency response of this amplifier stretches up to 50,000 Hz, for Hi-Res Audio Certified playback. Pioneer uses high-grade electronic parts and gold-plated RCA connections to ensure maximum performance. Speaker-level inputs allow you to install this amp in a factory system with no RCA connections. The amplifier switches its input mode automatically when it detects the high-level signal, eliminating the need to run a turn-on lead to your receiver or fuse box. Built-in high- and low-pass filters let you adjust the sound for your vehicle's interior, whether you're driving speakers or subs.
- Aluminum Top Board: A high quality cosmetic feature only available on LIMITED models.
- Pioneer Branded Electric Elements: High quality elements provide high sound quality and stable power supply.
- Gold Plated Terminals: Gold plated terminals provide the ability to maintain an accurate signal with increased electrical conductivity, prevent corrosion and provide enhanced durability with excellent resistance against wear.
- Hi-Res audio: High Resolution ability provides a super high frequency playback over 40kHz, and a wide dynamic range. Even if the source is not Hi-Res, wide dynamic range provides a more detailed audio playback.
- Variable Low-Pass Filter - 40 Hz to 500 Hz.: For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences.
- 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.
- 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.

Surprise
I just installed this amp to replace my failed kenwood excelon x600f. I did not expect the clarity, or quality from such a compact amp, especially one by pioneer. Main reason I purchased this amp was the rms ratings matched what I already had. Right out of the box with default settings it pushed my polk audio 6.5 components in the front and my morel maximo 6 in the rear with ease and crisp, clean response I was impressed and rather shocked to know I was missing something when I turned this little beast on. My other amp was failing on the rear channel plus getting slight distortion on the front. Now, i'm sitting in the driver's seat feeling my hair fly back while smiling ear to ear.(old pioneer commercial) Only thing I do not like is how the rca inputs are on opposite side of the amp. Made my install a bit awkward looking with the setup I already had. Other than that, this thing is downright lean and mean...

Pioneer 4-Channel Amp Review
I purchased this amplifier to power four Alpine Type R 6x9s. The sound is super crisp, and I have pushed this amplifier hard every day for over one month without issue. Its size is slightly large in comparison to my Kicker 800.1, but it can easily mount to seats, under seats, or to an enclosure. This amplifier provides great value, as it is the only one in its price range to have solid reviews and 100w rms/channel. You will not be disappointed.
