This is an impressive little amp! I paired it with 93db Hertz speakers (50w rms) and they sound fantastic! I can highly recommend!

I needed an amp that had 100w x4 speakers for my Kickers that are each rated for 100w rms. This was the only amp I could find that solves that problem without costing too much. Installed it, used it, and I'm satisfied with it! Sound quality is great and it provides AMPle power. Satisfied customer. 5 stars.

Added to a 2022 Mustang to power a 10" subwoofer, and 2 two-ways in the rear deck, to upgrade the existing "Bang and Olufson" stereo. Generally good results, after using a pre-amp DSP (AudioControl LC2i) to sort out the signal from the stock head unit. Has plenty of power, setting the gain about 40% level. The low pass and high pass filters work well, and I was able to custom tune to my ears. This is not a high end Amplifier, and you can find others that will cost you double or triple. For my needs it was perfect when you need just better and cleaner sound.

Have used this same amp before. The new one was defective. Was sent a replacement but box was all ripped and looked used. Sent it back and bought a different brand. Don't understand the used replacement. Maybe there all used. Buyer beware.

I don’t have an issue spending money when it’s worth it. This is worth it.Great quality, packaging was nice, the amp looks good and seems like it will hold up for a while.Paired with some kicker shallow mount tens in a Colorado in a sealed box and if I had to start all over again I would buy exactly what I bought.Running around 800rms and it tuned really well also.Plenty of juice, great features, small form factor so it’s a great behind the seat option in a truck, and seems high quality. 9/10 power and ground were hard to get seated properly. Inexperience and lack of patience may have been the issue though.

Great amp. Running a 12" sub and all speakers in my Prelude.

- Probably better for speakers than a sub- Sleek metal build that stays decently cool- Not as powerful as other amplifiers, but still good power.- Small, and can fit in tight spaces- Worth the money as a starter amplifier

Ich habe diesen kleinen Verstärker gekauft, da ich im Auto den Radioschacht für andere Dinge benötige und weil mit diese bunten Radios nicht gefallen.In Kombination mit einem einfachen Bluetooth Modul (ASIN B08T8XNCRD) lässt sich ein wirklich tolles Setup verbauen.Der Klang ist wirklich hervorragend klar und definiert und um Welten besser, als das was mein bisheriges Radio hergibt.Mit einem zusätzlichen aktiven Mini-Subwoofer bekommt man auch satte Bässe hin (z.B. ASIN B078PHCHSW).Das Gerät ist kleiner als ein halbes DIN-1 Radio und relativ leicht. Das Gehäuse ist aus eloxiertem Alu.Der Verstärker lässt sich als 2- oder 4-Kanalverstärker nutzen.Es wird ein langes Kabel zur direkten Anbindung an ein ISO-Steckersystem mitgeliefert.Als Eingangsquelle können der RCA-Anschluss (Kabel nicht enthalten) genutzt werden, oder direkt der Lautsprecherausgang eines vorhandenen Radios, mittels des separat mitgelieferten ISO-Adapterkabels.Ich hätte mir gewünscht, dass das Gerät noch mit einem externen Lautstärkeregler ausgestattet wäre.Das musste ich selbst mit dem einem separaten RCA-Drehregler (ASIN B075XN1Z3C) lösen - funktioniert aber sehr gut und ohne jegliche Störgeräusche.Klare Kaufempfehlung!

Purchased this amp to upgrade from my current mono-channel. It’s powering two 6.5” Kicker speakers in the front at 80 Watts RMS and two Rocksford Fosgate 10” at 150 watt RMS subwoofers in the back.The instructions and schematics are descriptive and easy to understand which aids in the installation proccess.The power is there with no clipping or distortion and the headway for volume has increased dramatically.The amp itself feels incredibly well built, firm metal casing and has a firm weight to it. The adjustment dials for audio tuning can be a bit tricky to access, would be nice if Pioneer provided a small flathead to access them easier.The standout features of this amplifier are the bass boost adjustment dial (which can be mounted in your vehicle wherever you prefer), the gold plated terminals and the selling point for me, being able to play audio in high resolution.A near perfect product, with minimal oversights.

Ce n'est pas un ampli haut de gamme mais il y a une sacré différence comparé au son avec uniquement l'ampli du poste d'origine ! Le son est plus puissant et plus chaud !Du coup j'ai mis un kit éclaté de meilleure qualité à l'avant pour être en adéquation avec l'ampli.De plus il est de taille réduite pour le caser facilement et les branchements sont aisés et fournis avec (prises ISO), par ex. aucun câble d'alim. à tirer du moment que votre poste est sur un fusible d'au moins 15 A, ce n'est pas comme avec un ampli traditionnel!Très satisfait.

Despite the immense power, the amp stays surprisingly cool, thanks to its efficient design. Installation was straightforward, and the build quality is top-notch—this thing is built to last.If you’re looking for an amp that can take your sound system to the next level, the GM-DX971 is the way to go.
