AK-380 Hifi Ampfilier

This little amp sound great and works flawlessly. Bluetooth connects faithfully along powering up . Plenty of power for reasonable volume levels

Performs as expected, and sounds great. The Bluetooth is a nice extra touch! Have had this for a while now and it has stood the test of time. The only complaint is that when hooked up to the headset jack to my television when we turn off the TV it has some weird static noise. If this were any other output such as RCA or Bluetooth this does not happen at all. Kind of weird, so really I wish this had an optic audio option, as that would fix that issue. Most newer televisions will auto set the volume lower after a certain time to protect your ears as if you’re actually hooking up headphones to this port instead of using it as an auxiliary audio port. It’s not really this devices fault, in the end.

With a coupon this was less than $30, and was well worth it. I needed a new FM tuner for my garage which has a speaker in the ceiling. The old tuner was failing and I also had a small bluetooth amplifier that it fed into before sending output to the speaker. The amp was fine but the tuner was having issues. This allowed me to replace both with one device and have both bluetooth and FM radio like I had before, but in a much more compact package. The tuner works great inside my garage and I tested the bluetooth with my phone and it connected easily. The only reason I deducted one point is that the FM tuner doesn't allow you store favorite stations in memory. It simply has a function to scan the local area for strong stations and automatically store them. I think it allows up to about 30 stations to be stored. In any event, I was disappointed that storing stations in specific memory slots wasn't available as it seems to have been a standard function of any digital tuner (even old analog tuners!) for decades. However, one feature that made this less annoying was that the unit appears to remember which mode it was in (line input, radio, or bluetooth) when it's turned off and then back on again. Since I mostly listen to only one radio station, I can just leave it set to FM mode and that station, and it seems to restart in FM mode and still tuned to the last station. So I can just turn it on and not have to fiddle with it each time I am working in the garage. It would have been nice to easily be able to switch between my three favorite stations, but it will certainly do. Otherwise, the sound quality was fine and the volume control knob worked properly. It has good strong volume which I didn't test for its full capacity as I don't need too much volume for my one stereo ceiling speaker. It did have stereo speaker wire terminals on the back that I connected to my speaker, and a wire antenna was included for the FM, which easily picked up many of the local stations. The instructions are fairly minimal, but enough to get me started with the functionality I needed. The build quality seems fairly sturdy with the metal case which has flanges with holes for easy mounting.

We got this for our food trailer, where space is at a premium. It is very compact, yet still has plenty of input options. The FM receiver gets good reception, and the Bluetooth is easy to pair. The larger volume knob is very convenient, and the solid aluminum case seems like it will be very durable. At this price, this is a great value.

Worked amazing powering my 70s realistic mach one home stereo speakers. Great sound quality and great power for its size and price. I broke mine trying to strap it to my motorcycle so now I need another one.

Great value for the quality, I use it to power outdoor speakers. Sometimes it’s left powered on outside in the elements for weeks at a time and still works great. Installing and connecting wires is very straight forward. Noise level isn’t bad but not nightclub loud, Bluetooth range is about 30-40 feet

Purchased this in November 2022 and set it up to run the back patio speakers. It was enclosed and completely shielded. Would only turn it on when it was used- about 1 day a week for a few hours. It really did not get used much. Last week- the entire left channel output died!! Had to rewire all the speakers on the right channel. Will continue to use it until it dies completely- but it probably won't be long now. Update 08/31- The seller has reached out and they are replacing it! That is awesome!! Update 09/04- Recevied the replacement amp and that is all good. Decided to open up the old one and see what was going on. Immediately found the 3 IN5399 diodes had burned up. Went ahead and replaced them all. Then noticed this thing was running 0.33UF capacitor. Went ahead and replaced those all with 1UF capacitors. This amp sounded good stock. But now..... NOW, after this simple repair / upgrade it sounds freaking amazing!! The bass really pounds now.

I was pleasantly 😮 Surprised at How Functional this Amp is as well as the Power. Love the Features (super compact size, FM/AM Radio Tuner, slim Remote, Bluetooth connectivity <to my Cellphone>, Digital display, crisp Sound Quality, and RCA Cable output) plus the Power it delivers to my POLK Patio Speakers.
