Review: Small Yet Mighty!! - This amp provides a lot of bang for your buck! You havento do a little minor assembly, which I wasn't expecting, but it's simple and a screw driver is provided. I'm powering it with a 20v DeWalt tool battery to drive no less than seven speakers in a custom enclosure - 1ea 10" Klipsch sub, 2ea 10" Ashdown mid/woofers and 2 pairs of 2.5" Klipsch high frequency drivers with 1" poly dome tweeters. And it effing rocks! After pairing it in my phone, the Bluetooth connects quickly every time I power the rig up. The fidelity is excellent. Crisp highs, detailed mids and plenty of power to drive the sub, especially with the sun frequency set higher. At lower settings where it rolls off more mid-lows its power does drop off, but, with a tiny plate amp like this that's to be expected. I'm honestly blown away with how much bass thin amp can produce. With more use I will have more info on longevity (and battery life, but,that's not related to this review). Well worth the money for what you get!!
Review: Super Amp!!!!! - Great sounding amp worth every penny you won’t go wrong here excellent power must have…
