Pioneer GM-D1004 400 Watt 4-Channel Digital Class D Car Audio Amplifier
Excellent Amp!!! I recently purchased the Pioneer GM-D1004 400 Watt 4-Channel Digital Class D Car Audio Amplifier and I'm very happy with this amp. It's surprisingly small, at 7 1/8" wide x 2 1/2" deep x 1 1/2" high it will mount almost anywhere. Even though its small, this little Amp still packs a mighty big punch and also offers versatility, as it puts out an impressive 45 watts x 4 channels @ 4 ohm, or 45 watts x 4 channels @ 2 ohm (bridged), or you can run 90 watts x 2 channels @ 4 ohm, or you can run 3 channels so if you have 2 mid range speakers and a sub you can power all 3 with just this one little amp. Very reasonable price, you just can't beat it for what you get!!!. Whether you are just looking to upgrade from your factory amp or you want to power your mid range speakers this little amp is the perfect choice..... size, power, price.... you can't beat it. I highly recommend this product to anyone looking to upgrade their sound system.Verified purchase: YesCondition: New

It Causes Clipping on my pioneer kevlar 6x9 component speakers. Not enough power :\
This tiny amp is too underpowered to run higher quality 75 watt+ rms speakers. Im sure it would perform better with lower wattage coaxial speakers that arent meant to produce good punchy midbass. Dont get me wrong this lil amp sounds good and definitely better than what my double din kenwood excellon stereo can dish out. But not enough for my power hungry Pioneer TS-D6902R 6x9 speakers. I guess i shuda known better. I got carried away by reading the reviews. I will have to either amp up, or downgrade on my mids. Otherwise its a cool lil amp. I personally cant crank it up too high for too long or it will get into what seems like protection mode and lower my volume substantially no matter how much i turn it up. I have to power off & on to make it work well. And thats while lowering the bass enough to where the speakers dont clip. Because they will clip if you try to get any decent midbass on high end components. Even when bridged to 2 channel and doubling up the power to speaker. Bottom line, it should work great on small wattage speakers. It uses only a 15amp fuse, so what can you expect really?Verified purchase: YesCondition: New

Good low wattage small frame amplifier
Installed this unit in a 2014 4-Runner hooking it up to speaker out inputs of the stock Entune stereo. Mounted the amp behind the glove box next to the stereo & tywrapped in place tightly. Sound quality is good, basically Entune sound boosted up a bit in wattage from stock. Bass has increased giving my new installed JBL's more power to kick. It is about 25% louder then stock, not a huge difference in wattage. Connected power leads directly to stereo 12V and butt spliced to all speaker in/out leads. Not difficult to install, about 1hr. JBL's are about 2-3 ohms and this can handle 2-4 ohms and is one of the reasons, besides small frame size, why I purchased this unit.Verified purchase: YesCondition: New

Pioneer Amp
Ive got this amp hooked to a Kenwood Excellon radio with 6 x 8 Infinitys front and rear x 22 watts It has made a world of difference to the sound! Those speakers greatly benefited from the 45 w watts pumped to them now. I have increased bass, which was lacking before, which i figured was a shortcoming of all 6 x 8s . Ive mounted it in a empty glovebox, just by itself as that little sucker gets warm, real warm but only when its cranking. Get one you will love it.Verified purchase: YesCondition: New

Great
Big sound in a little package. I hooked this up to some JL audio C2 690 6x9's (highly recommend) in my front doors and JLAudio components in the rear doors. I then used dynamat extreme (highly recommend also) now my Jeep WJ sounds amazing. Really don't even need a subwoofer these JL's have lots of clean bass. Can't believe it for the size of the speakers they put out a lot of bass. Highs are crisp and clear also. This little amp works really well so far. I'll be hooking up my JL audio sub tomorrow like I said probably don't need it but hey I love lots of nice tight accurate bass.Verified purchase: YesCondition: Refurbished

Pioneer compact amplifier
This little amp packs a punch. You will hear the difference instantly. It is very easy to install in line with your door speakers. I'm very happy with the product. Also, its size makes it very easy to hide.Verified purchase: YesCondition: New

Great component!
The amp provides exceptional power for its size. It's a perfect power application to pair with my Pioneer MVH-S501BS. Also the power ratio to my Rockford Fosgate R500X1D w/ a P2D4-12 in a sealed box is impeccable. I forgot to turn up my Bluetooth device volume and discovered this thing can really blast, even with my convertible top down.Verified purchase: YesCondition: New

Easy installation. Sounds great.
Have this installed in my fairing on my Harley because the stereo wasn't loud enough. Installed this and sound quality improved a lot. Power taps into the head unit power and I did the high output signal so didn't even need rca cables. Liked it so much I bought another for my car.Verified purchase: YesCondition: New

Great little amp.
Lots of punch for car door speakers. Small enough to tuck in behind a head unit. Even with medium efficiency speakers you can make it too loud to be close (Think Miata) and no distortion. Good s/n ratio, not noisy at all.Verified purchase: YesCondition: Pre-owned

They bump!
The ammount of deep lows that these guys kick really surprised me. I have them in a box that is .86 cubic feet per speaker. I wasn't expecting much, but I hooked them up to a 1600 Watt amp, and they shook my friggin' truck! Very pleased with these thumpers!Verified purchase: YesCondition: New
