I’ve had kicker and Rockford fosgate but this little amp makes my car speakers scream . I think I better quality than the other brands that I had. For the size that it is it’s very powerful. Value for the money is perfect.

I needed to replace an old amp that developed a crackle to run Polk 6.5/tweeter separates and single 10 4ohm sub. This isn't as loud as my old amp but it sounds clean and the price was right. I'd buy it again.

I ran this amp with some alpine dual coil door speakers(6x8s front,5x7s rear) in my 2003 f250 crew cab. Along with an alpine type s 10” woofer paired with a 200 watt arc audio amp. It might not sound like much but it slaps!! Volume all the way up with the amps tuned and equalizer tuned correctly there’s zero distortion, loud clean crisp sound and thundering bass. I’m very happy I decided to buy the better equipment.

This amp is powerful! Obviously it's Class D but wow - I replaced an old MRP F250 from ages ago with this unit and it drives my JBL Stadium components with ease. Puts out more than rated aswell, my test sheet says 112w! Very good quality as usual from Alpine. Highly recommended! (Note: Rated power is 80w x 4 @2 ohm, 63,3w x 4 @ 3 ohm and 55w x 4 @ 4 ohm for those that have 3 ohm speakers)

Installed in a ‘06 Toyota Corolla. Look no further if you enjoy quality, crisp sound. No shaky rattling bass. Paired this amp with 6 speakers from Infinity. 1 set of 3-way 6x9 Infinity Primus and 1 set of 6.5 Infinity components. 6 speakers total and it’s all the power I was looking for. The amp output tested a little higher than what was advertised. Exactly what you want. Can always dial the gain back a little if you have any clipping or distortion. This was my first amp install and paired it with the NVX 8gauge amp kit.

Honestly, it has more power than I expected. Great amp for the price. My ‘71 VW Bus rocks once again!

Very clean power and power ratings are understated verses over stated as with most amps. Comes with a certified output birth certificate. Mine showed 123 @2ohm per channel. Which is truly closer to 130 since music is dynamic not just a single test tone used for certified testing.

At 4x55W (RMS) this Amp provides just a little more umph than the very common 50W competition in this price range. Construction is solid. No distortion at a volume that is too loud for the average listener. The manual states that this Amp is rated for 80W per channel at 2 ohms (RMS). I was quite impressed that the manual included the factory technician's hand written value of the actual performance for my specific unit. (92W) Paired with my new 12" powered subwoofer I find myself looking for excuses to run a few errands. Only criticism is that it did not have any pre-outs.
