### ⭐⭐⭐⭐ Good little amp!
*by D***Z on August 29, 2017*

I purchase this amp to drive two outdoor speakers on my deck. I paired with a 24VDC Switching Power Supply, and installed in a waterproof box.First off, I think the amp is fairly well built. I had zero problems's installing, powering up and establishing a Bluetooth connection to my phone.The sound is clear with little distortion across most of the volume range. It does however have a moderate clip at full volume. While I did not measure the output, I would say that the stated 100W per channel may be overstated. (The previous amp driving the same speakers was only 50W and was very close in sound output.)The Bluetooth range is acceptable for my application (30'). The Bluetooth does cutout from time to time for a second or two but I haven't pinpointed whether its a phone issue or a amp issue.Since its mounted in a weatherproof box on my deck, I have it powered 24/7. So, it has been working for the past several weeks without issue.All in all, I think its a good little amp and would recommend!
