  1. Punkadelic19

    Installed this amp only bc they didn’t have what I needed in stock. Its not strong enough for the speakers I have but it’s turned out to be all I need

  2. Nick40

    What you expect from Alpine quality products and support.

  3. Antho

    love this amp, it pumps 8 speakers and a Subwoofer in my Jeep with no problem.

  4. Ammy

    Good looking size amplifier for my new Alpine speaker set. The sound that it gives is incredible and fit perfect under back seat on my 2015 Silverado.

  5. Derek

    Bought this to replace a previously installed amp. The product is compact, easy to adjust and has plenty of power for stock/oem or aftermarket speakers.

  6. kevjac

    Using this amp to run the midbass in the door for my 3-way setup. I have the amp bridged @ 4ohm. The T2 6.5 Fosgate’s pounds like they’re subwoofers

  7. Airfare24

    Meets all expectations. Drives my speakers to great sound, nice and loud.

  8. Dmelchoir12

    Alpine has always proved to be a great product for a long time

  9. Ndcapes

    Small doesn’t get hot. Nice options and very clear sound

  10. nilovelour

    this amp is so clean. this amp powers 4 speakers in my convertible. my speakers scream with the help of this amp. well worth the price

  11. Woodman

    Amp goes well with the audio equipment. Great sound and easy to install.

  12. Bobby

    I bought this to push my alpine component speakers and it is a great marriage.

  13. Alpine

    I love alpine. This amp works amazing when it has the s-series speakers.

  14. Toochman

    Just installed this amplifier today, wasn’t sure if this was gonna be enough power to drive the stereo system and sound good in a convertible with the top down. Wow! This was an Awesome choice! I’ve had Alpine stereos and speakers in the past and was always happy with them, now I can say they also make great amps. Would definately recommend this amp to anyone looking for a nice upgrade to their sound system! Have only had it installed for 1 day, but this one replaced an Infintity amp that was of the same class and power and this amp sounds alot cleaner!

  15. Scott

    The only reason I’m not giving this a 5 is because I have not used it enough to see if it lasts. SO far, It produces MORE than enough power, but more importantly is CLEAN super clean Alpine sound. NO distortion at all.

  16. btotherian

    Great amplifier. Easy to install. Turned car into an amphitheater with tremendous bass added to speakers

  17. Great

    Have loved this since we hooked it up. Ease of use. Perfect for what I needed.

  18. Greg

    Love this amp. My setup I used this for powering two 5-way 6x9s in bridged mode, in my back seat in separate enclosures. Bridged mode delivers about 150 watts to two channels. Perfect for those 5-way 6x9s. Added a ton of extra sound in my car that my door speakers couldn’t do alone.

  19. Scooby

    Not one issue. The sounds hits right where I need it. Quality item

  20. Goaliemom

    Excellent product and easy to install. Great sound.

  21. walnut

    works perfect on my 4 6×9’s in my saddle bags on a 2000 ultra classic

  22. Kicker

    Very disappointed not what I thought at all for the price!!!!

  23. Felipe

    Plenty of power to feed 4 door speakers. The sound is a bit harsh on the 2.5k range! But it might be my speakers! I can not imagine anyone wanting more power for door speakers! I do wish it had a band pass filter though! For the money, it can not be beat!

  24. Jwallscott

    This is great product and it is well worth the price. I suggest getting it.

  25. dhanna83

    My previous kenwood amp stopped working. Found this one online at a decent price and alpine is always good quality. Bought and installed the same day and now my car system is sounding awesome again

  26. Mark

    Alpine 4ch works like a champ. Runs my from and rear speakers without any distortions. Sounds crisp and clear

  27. Alpine

    Awesome great sound. More power than I thought. Love it!

  28. AlpineJoe

    Crisp sounds for a compact AMP. Does not distort at relatively high volume level. Has good amount of watts to push 4 – 6x9s kicker DS series. I wish the AMP had a deep base output to push the lows on the speakers without having to buy a separate sub woofer. Overall this is a good AMP to pair with Alpine ILX-W650 head unit. Can’t go wrong with this purchase.

  29. view

    I was quite shocked by its power it had i am a big fan of pioneer and wasnt expecting it to be of great value but this one really out did itself

  30. TheJoker

    Awesome little AMP, Provides plenty of power to my 4 Apline speakers.

  31. kebmo

    filled sound from headunit
    clean, clean sound throughout power range, pushing infinity kappas
    good range, full harmonics

  32. Jay1234

    Great 4 channel small and compact easy to use great sound for the price

  33. GodlikeEC

    Nice replacement for the one I had installed previously.

  34. Jeffrey

    Bought an Alpine speaker system for the car. Sounds terrific. Can’t imagine why Mazda used awful sounding speakers as OEM. They were terrible. Does Mazda wonder why a customer doesn’t return to buy a 2nd Mazda? The original speakers were made of paper.

    But the Alpine speakers and Alpine amplifier are the best.

  35. Alpine

    This amp is doing a great job of running my door speakers. I would buy again if I needed to.

  36. Middat

    Amp pairs well with the alpine s series speakers quality sound i got hooked up with 2 12dvc kickers

  37. AEBAS

    I got this to replace my bikes existing amp. Sure glad I did. This guy sounds wonderful. I am using a SONY AX7000 HeadUnit. This guy pops! I have a 8 speakers, all Rockford Fosgate and this amp has some crisp highs and thundering lows. Something my last amp just never did for me.

  38. JP21

    Alpine is a must for all of my car audio purchases!

  39. Goose8880

    Have great power and a small footprint. I was able to bridge the channels and push a 3 way focal set with this

  40. Speakers

    I bought this Aunt to power one JB at 12-in subwoofer and my kicker CS speakers works great extreme power for the price

  41. RedMustang202

    Nice amp,Buy One! easy hookup powers a pair of 6×9 alpines with no problems.

  42. Ccruz

    The build quality is perfect, sound has improved a lot. Excellent amplifier. Good price

  43. SubaruFamily

    Does exactly as promised! Happy with this purchase

  44. Go2Guy

    My first experience installing an amp and installing this Alpine amp went without any problems. The amp works as it is supposed to and the resulting sound is outstanding.

  45. Allen

    Only lasted 2 years. I don’t drive the truck much either.

  46. Kooldaddy

    My neighbors can hear me blocks away lol and i like it lol

  47. Yourstruly

    My neighbor keeps complaining that my subwoofers are too loud and he can’t sleep lol

  48. TimM

    The amp works fine I really like the fact that it is Alpine and my entire system is Alpine. I wish I would have been able to get an Alpine mono for the subwoofer but this is what they had and it was too good of a deal to turn away from. All in all it does push the subwoofer.

  49. Goldstec

    I needed an amp to update my 22 Ford Ranger crew cab. Puts out 55 watts to four Kicker KS 6.5 speakers. Bery clean aound

  50. ThebigD

    Amp has a small footprint but pushes my sub perfectly. I wanted more bass in my truck and this is just what I needed.
