HIFI CHIP:ZK-502C Adopt TPA3116D2(with AM Interference Suppression Function) Chips, With Excellent Sound Quality. It Ensures That Even With High Power Operation For A Long Time, THD Is Less Than 0.1%. WIDE INPUT VOLTAGE: DC 9V-24V, Can Be Powered by 9V/12V/15V/18V/24V. TWO AUDIO INPUT WAYS:User Can Directly Connect with Wireless Bluetooth 5.0, or Choose the Headphone (Line in) Way. PROTECTIVE FUNCTION:This BT Amp Is Designed with Protective Case, Over-voltage Protection, Under-voltage Protection, Over-heat Protection, Short-circuit Protection. TIP: adequate output power is required when the audio input is sufficient and the power supply voltage/current is sufficient, the relative power will be higher. Different impedance horns will have different output power.In the case of sufficient voltage and current, the larger the impedance horn, the smaller the relative sound power, please pay attention!.

So far, so good. Very impressive!

Purchased to power Polk speakers in our bathroom. Tried them out first on an old pair of Aiwa speakers in the garage and couldn't believe how well this thing worked. Then I plugged it into the bathroom speaker and it worked like a champ again. The only downside is that it worked so well that I went out and bought a couple of outdoor speakers and had to buy a second unit to power them. It's going to be expensive. If you're old school and have one of those tower speakers, this is all you need toโ€ฆ

Pros
  • Home Audio
Cons
  • Cable is shorter than other picks

Great sound + easy assembly = rock in no time

It makes a lot of noise that this is an 'expert build' but if you can assemble Ikea furniture you can assemble it. Assembly takes less than 5 minutes and the build quality is relatively reliable for an outdoor structure. While I highly recommend using a case (or 3D printing your own) to store this item, the built-in assembly is structurally sound enough. The design couldn't be simpler, with a large volume knob to turn it on and off and turn up the volume. Pairing is easy, but I'm not a fan ofโ€ฆ

Simple but nuanced (you need a second switch and mounting hardware)

So I got this bluetooth board and hooked it up to a power board with a lithium battery and some speakers. Wall connection was very easy and the sound quality was pretty damn good for the price. But. There is one thing about this board that really annoys me and I just can't let it go. The volume control is also a switch. You would think that this switch would turn off the entire board. But that's not the case! It can turn off the amplifier, but will not turn off the bluetooth radio. If you turnโ€ฆ

Pros
  • Receiver and amplifier
Cons
  • No insurance

Just unbelievable!

I don't know what the response range of this amp is, but I can tell you it's AMAZING! With this board and some extra materials lying around, I was able to make a speaker that sounds better than my $20 BT speaker I bought a few years ago. It was literally a 20 minute test setup to test the amp for yourself. also my first attempt to weld plastic. It looks like crap but gosh it's solid! if you are a handyman. I highly recommend building your own speakers! Edit: I had to update the review and put a

Pros
  • TIP: Sufficient output power is required, if the audio input is sufficient and the supply voltage/current is sufficient, the relative power is higher. Horns with different impedances have different output powers. With sufficient voltage and current, the following applies: the greater the horn impedance, the smaller the relative sound power, please note!
Cons
  • Out of fashion
