Could be better

Great power output and the sound quality on my 2 ways was really nice. My components however had some bright tweeters that no matter what I did even with an active setup I couldn't resolve completely. When I swapped to a different manufacturer with more extensive ranges and filtering the problem was solved.

Fantastic amp. Paired this with some Kicker CS series speaker and it gives them plenty of power and makes them sound incredible!

Great amp, depending on your setup

I used this as a 3-channel amp, powering Polk Audio DB 652 full range speakers in my front doors, and a JL Audio 10W0v3-4 in a sealed enclosure in the back of my Honda Accord coup. The idea was to eventually expand my system to use this to power 4 full range speakers, while adding a mono amp and another sub. I will say that the front speakers sounded great! They were plenty loud, clean, and accurate. I can only imagine that (4) 100w speakers would be too loud for my little car. Unfortunately, the bridged 300W going to a single sealed 10" did not match the power level of the front speakers. Perhaps if I used a ported enclosure, or if I had a small hatchback it may have been closer; but I would not recommend the setup I had. Another important note is that the included remote knob only controls the bass boost (at 50Hz), not the bass level (total volume output for all bass frequencies). The description states it, but I did not pay attention or know better and found the knob pretty useless for my purposes. I would absolutely recommend this amp for full range speakers in 2 or 4 channel mode, but found the 3 channel setup was mismatched regarding power output in my car. (I should note that I returned the amp and sub due to the above, but individually they all worked great).

Thanks To Crutchfield

I don't know the first thing about car audio, much less amps. I called Crutchfield because I wanted to upgrade the horrible stock sound system in my new car and they made some great recommendations that included the Pioneer GM-DX874.

Rock solid Amp

This AMP slaps hard! I paired it with some Polk Audio DB 6502 in the front and some Polk Audio DB 652 in the rear on my Forester. They sound incredible, especially after doing some EQ and settings adjustments on the head unit. Make sure you set the gain correctly, out of the box NORMAL on the gain was WAY too high for my Pioneer DMH-WC5700NEX HU. Which outputs 4V on the pre-amps. The gain looks like it can adjust from 6.5V to 0.2V. It also is set separately for A and B channel which is nice, but can be overlooked if you are doing 4 channels.

A Huge Upgrade for Me

This replaced another, cheaper amplifier. I cannot explain in words how much better this one sounds. (Best expressed in musical notes I suppose). The bass was fuller, the highs are purer. Most of all, you NEED 100 watts per channel to hear your speakers in a convertible. The extra sound makes a huge difference.

Good power but unreliable

Had this amp in my truck for almost 6 months when it started to play static at full volume from 2 channels, luckily my speakers weren't harmed. Sent it out for warranty which was a major P.I.T.A. got it back a month later and now I don't know what to do with it. I'm afraid it will fail again. I bought it another retailer if that makes a difference.

Great price even better features

I've installed a few of these and to be honest never was a big pioneer fan but these amps are awesome! Pioneer out did themselves on these. The fact they are 1ohm stable stereo and 2 ohm stable bridged is outstanding. Reminds me of the old Boston Acoustics amps. This lets you use these amps in a bunch of different wiring configurations. Not only are they versatile but are fairly small and sound great. They really power the potential out of anything you put on them. For the price I feel they're a steal.

Great Buy!

This is a very nice amp. It has a nice amount of weight to it, but still a small footprint. It plays loud and exceptionally clean running the signal through a LC2i from a factory Ford receiver. I have this amp running two sets of kicker 47KSS6504 sperates in a 2014 Fusion and it absolutely fills the car with music. The mid bass and highs will easily overpower your listening comfort. Very satisfied with this cool running amp.

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.

Great value for power

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.

Very happy with this purchase

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.

Solidly built amp that pumps out good power

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.

Pioneer GM-DX874 Amplifier

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.

Surprising Clarity from a class-d!

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!

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!
