    How do you review an amp? It sits tucked under my dash. Visually I don't see it, it powers my stereo just fine.

    Game changer when added to the Alpine Ilxw650 meshless head unit. Fits behind head unit and can give more control of highs and mods.

    I can't give a great review on this product because I never heard the speakers before the amp was installed. I honestly don't believe that I needed this amp. I should have waited and listened to the speakers without the amp first. Free installation on head unit, speakers, amp, backup camera, and remote start with Total Tech Support was definitely worth it!!

    No, I would not recommend this to a friend
