    • Nice little amp that was easy to install
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.

    • Clean power, compact size...
Compact, runs cool, very clean output. Can't say there was any noticeable sound quality differences from the Kenwood Class D I replaced, but this amp runs much much cooler, which was my main reason for replacement, my old amp would run dangerously hot for the carpeted space that I had it installed.. HPF works great, easy setup, terminals and controls clearly marked. ... show more

    • Clean, Crisp Sound
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. ... show more

    • Best amp I bought so far 😤
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.

    • You can’t not have an amp!
Honestly, it has more power than I expected. Great amp for the price. My ‘71 VW Bus rocks once again!

    • CLEAN power
Unlike amplifiers rated at 10x the wattage, these put out more than they're advertised to offer AND do it without distorting the sound. I'm a HUGE audiophile. EVERYTHING I OWN has a good stereo in it. Hell, I have 3 HUGE stereos in my house! 1 upstairs, 1 downstairs and 1 on the screened in rear deck/sunroom. My vehicles are no different! I HAVE TO GUARANTEE that when someone pulls alongside of me "thumping" (C)rap, that I don't have to listen to their shit sounding stereo and in at least 2 of my vehicles, can force them to hear whatever I have on! Plus, I am often on the road between Tn & Pa and a LOUD, clean sounding stereo is a MUST! I literally never turn the things down, only UP! I LOVE my music, but it has to sound GREAT! I DETEST added distortion. This amp is in a small vehicle/beater so it need not be HUGE. It powers 4 Infinity KAPPA 6.5" speakers, both component speakers and you'd be amazed that all of that sound is coming out of such small speakers. I have a pair of small, under the front seat powered subs to round out the sound, and except for the lack of "air moving" large speakers, the sound quality is impressive! Alpine has been offering higher end car audio since before I began driving in '87, and I'm happy to see they STILL do! Buy this. You won't regret it! Kirk ... show more

    • Excellent power for the size and great for High-Res audio!
Review Image by Quit Seven Six Quit Seven Six
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) ... show more
