Surprise
JLCIII Posted
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
Logan Posted
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.

This is a nice quality amp. I installed it easily and it made a complete different with my aftermarket door speakers.

Feel the power!
Ronnierednail Posted
This is my first experience with an amp manufactured by Pioneer and I’m impressed so far. I like it so much that I’m thinking of buying another Pioneer amp to power the subs.

Great amp. Not so great service
ChrisM Posted
Great amp. Had it installed through BestBuy. They told me to go to a store to have it when it was really at a different store. Really appreciated the inconvenience and also how they scratched up my door. Will not consider them for the speaker install!

Fantastic Amp & Vaule
KidStereo Posted
Excellent sounding and powerful amplifier. I compared it directly with an audison amplifier which cost twice the pioneer (though it was rated at 75x4), and there was virtually no difference between the 2. Maybe the Pioneer was a tiny bit less detailed, but you would have to really pay attention to notice the small difference. The Pioneer also did control the speakers slightly better at max volume, as it has more power. Definitely runs warm to hot, but never excessively & never went into protection mode. The only negative is the controls are on the sides, so making minor adjustments (which are an absolute must to set levels) is a bit of a pain once the amp is mounted. Anyway, highly recommend.

Good amplifier
OscarMartin Posted
Easy to use. Clear sound, small devive and nice look.It's a very good device for a standard installation for ordinary people who simply want to increase the sound level, without the need for highly professional installations.

Not bad but input jacks are easy to break
DavidB Posted
I recently purchased a Pioneer amplifier. It was very easy to install, and the setup process was straightforward, even for someone without much technical experience. However, I was disappointed with the quality of the RCA jacks. One of them broke shortly after installation, which raises concerns about durability. The dented output connection was also frustrating to see on a new unit. Overall, the sound quality is decent and performs okay for everyday use, but the build quality could definitely be improved.

Thank you for providing the feedback on the GM-DX874, we appreciate your time.
I would suggest visiting a local Best Buy and having them inspect your amplifier. The amplifier should not be damaged from a normal installation process. <img src="https://s3.amazonaws.com/stratos-logos/logos/PUSATechAnswers.jpeg" alt="PUSATechAnswers" title="PUSATechAnswers" style="display: block !important; margin-top: 2em !important; border: 1px solid #ccc !important; padding: 2px !important; background-color: white !important;" /> - Rated 4 out of 5 stars

Fantastic amplifier, using for two 12” subwoofers in a trunk, and beats them better than ever before! Great for the price, and compact too!

This amp hasn't given me any troubles. The sound quality is great, which is always a worry for me. It's not super bulky and finding a spot for it was very easy.

Pretty powerful amp in a small and well built package. It’s definitely worth using for a good auto audio system.
