    • Powerfull
I recommend this amplifier, it is very compact and the functions it brings are very good. It doesn't make any noise from the car's engine, the sound is very clear and powerful

    • 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.

    • 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

    • Alpine quality for a great price.
I needed to replace an amplifier that died and I didn't want to skimp on quality; so when I saw this amplifier at a great price I didn't hesitate. First I am really happy with the build quality and aesthetics, my only disappointment is the wire terminals are just small set screws without a wire clamping system. I recommend terminating your wires with pin connectors. For the power and ground wires(8 gauge), I had to improvise pin connectors from larger gauge ring terminals. This improves and makes connections secure. I have been impressed by the sound. Punchy, deep bass, smooth mids and highs. Some of the improvement may be because the old amplifier was mounted under the rear deck on metal, which probably created a ground loop, and heat dissapation issues. I mounted this amp to the trunk liner with some plastic spacers underneath for airflow and wood backing behind the liner for reinforcement. This amp was about $90 less than the newest Alpine model, so this was an easy decision and I am cruising with great tunes again. ... show more

    • 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

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