Pioneer GM-DX874

For a novice like me it took about two months to get this Pioneer GM-DX874 amp and my Pioneer Pioneer TS-Z65F speakers in, but, WOW!, it really cranks now and sounds great, much improved bass compared to stock radio output! I installed it mounted on a PVC board under the driver side rear seat of the crew cab.
Pros: Has high grade audio components, gold plated RCA inputs, bass boost knob.
Cons: None.

Great value for power
Crutchfield customer from Los Gatos, CA on 7/31/2020
I bought this to power 2 pair of 6 x 9 three way speakers and it gives them a much more rich sound. It was easy to follow the directions and hook up, looks great in my vintage van and is a great value.

must have

awesome for my first amp. Found out quickly why people pay others to install them but for first time it went good. Very happy with the sound and quality so far. Needed to ad a sub and amp for better bass but this is definitely a must have for a good system
Pros: small Easy set up for beginners Efficient hasn't overheated Even at full blast for a long time
Cons: should of gotten the 5 channel so I could easily add an amp. But I tried to be cheap lol Could of came with tips on how to wire everything. Came with instructions as if everything was pre-wired in the car but it was my fist time installing an amp so it was my lack of know how. Overall the products great though

I've been a fan of pioneer for over 20 years this amp sounds amazing with the 6.5 components it's unbelievable the sound you get power is the key
Pros: Limited addition with the gold rca input
Cons: Power ground and remote inputs are always at a weird angle you have rise it higher than normal to get the wires in nice and snug

Very happy with this purchase
Steven from The Republic of Texas on 5/4/2020
I went with Pioneer, primarily because I have decades worth of great results with them but I have to say that this amp is quite a bit different from what I've worked with before. I use this amp to power my door speakers in a 2014 Nissan Titan and the sound that comes from this set-up now is almost overbearing. Instead of having to crank the volume up to 30, where it's just about to break-up and go to crap, I can now listen comfortably at about 20 and not have to listen to any road noise and, if I choose to do so, I can still crank it up without any distortion or break-up. This amp lacks the "pops" common with previous amps at start up and I haven't noticed any other unwanted noise at all. Paired with a Pioneer 500 x 1 for my sub, this is a formidable power unit that has thus far out performed my expectations in the price range. Size-wise, though not necessarily a compact unit, it easily mounted out of the way, under the passenger side rear seat in my Titan and, unless you're looking for it, you simply don't see it.
Pros: Great value. Great sound.
Cons: None that I'm aware of.

Solidly built amp that pumps out good power
Crutchfield customer from Bentonville, AR on 2/27/2020
This amp is solid. Nothing seems flimsy on it. Connectors are all solid as well. Seems to be putting out the power it claims. Its been installed for 2 days so far and its great. Doesnt get very hot. Sound quality is great and there is very little noise from the amp through the speakers, you can only barely hear it when no music is playing. I have it pushing Polk DB 6.5" speakers in the front and bridged to push a 10" Image Dynamics ID10 subwoofer in the rear. It does this well.
Pros: Compact size, solid connectors, powerful, bridgable at 2 ohms
Cons: None yet

Pioneer GM-DX874 Amplifier
Crutchfield customer from Paso Robles, CA on 2/24/2020
I purchased this amp to add to a Pioneer AVIC-5200NEX receiver, Pioneer TS-A1686R front speakers, and Pioneer TS-A6986R rear speakers in my Pontiac G6. I was looking for something to power the speakers that would have plenty of power, and hopefully some bass response I was looking for. The TS-A6986R speakers are rated at 100 watts RMS. I wired the recommended 4-gauge power cables, and amp pre-outs from my head unit to this amp. I was not disappointed! This amp easily powers my speakers and more! I've been all smiles every time I drive anywhere with the stereo on. I love the bass boost knob- I can adjust the bass up without having to go into the EQ settings for songs that are a little lighter in the low end. I've been able to shake my rearview mirror really well on several occasions. This amp perfectly brought life to my system, and I love it. It is a solid performer, and my music sounds great.
Pros: Has plenty of power, adjustable bass boost.
Cons: None.

Surprising Clarity from a class-d!
Barret from Ellisville on 1/23/2020
Well crafted exterior, well placed wiring terminals, ease of access. I've used many class a/b amplifiers circa 1985-2000, and very skeptical about a class D amplifier above 100hz. This amplifier even sounds better than my 1987 PPI 2050, I'm very surprised at the quality for the price!
Pros: Cosmetics and finish, installation, quality output!
Cons: None yet.

It is great so far. I had bought a Rockford fosgate 75w rms 4 channel that sounded really good, but felt I wasnt getting enough power to my new speakers. Installed this yesterday, and so far it is all I was hoping for.

Davis from Reno, NV on 6/30/2019
So far this amp is proving to be much better than the MTX four channel I had previously. It has more power, and is more reliable. The design isn't kind of chunky and weird IMO, but nothing to complain about otherwise. Pretty decent price on this one. So far so good!
Pros: Solid
Cons: Weird styling cues

This amp kicks! It is compact and made well. I really love the matte black finish. It was easy to hookup and very easy to bridge together to my speakers. It stays cool and it has a lot of power. I am very happy with my purchase.
Pros: Compact size Affordable Powerful Looks nice
