Bluetooth Mini Audio Audio Amplifier - 100W Dual Channel Wireless Amplifier Receiver for Home Speakers - Power Adapter Not Included

I paired this with an old set of Polk Audio Atrium 4 outdoor speakers that the previous home owner had left mounted on my back patio. I wanted a small simple amp for under $100. This item was perfect on both counts. It produces great sound and plenty of volume for me. The blue tooth connection with my IPhone works great. The amp is only about twice the size of its own power transformer as you can see in the photo. Very compact. I’m going to order a second one for use in my garage.

I built a nice shelf on the wall of the house next to the covered deck so when having a party people can plug their phone in and hook up and play music over the speakers. Hooked everything up and tried it out. It didn't too loud but more than enough for a small BBQ or party. A week later I went to use it while I was grilling and I got a garbled mess thru the speakers. I switched to bluetooth and it kept popping and the sound was awful! I tried again the next day and it no longer works. So I got one use out of the thing. Don't waste your money.

Great amplifier, amazing value as it includes Bluetooth. This amplifier was extremely easy to set up and sounds great. I am impressed with the overall quality of this unit.

It's not going to win any awards, but this thing was a pleasant surprise. The wife and I moved to a tropical island and bought a condo that came loaded with the other people's crap. One of the things included was a crappy stereo that was so corroded from the salt air I couldn't even get it to turn on, and a set of AR speakers pointing toward the front wall of the condo that opens up onto the patio. This thing did the trick. We don't want to blast anyone out. Just listen to music while looking at the sun set over the Caribbean. Bluetooth hooked up to both my Macbook Pro and my iPhone. No issues at all. It took longer to cut and strip the speaker wires to get fresh wire than it did to unbox it, plug it in and get music coming out of it. I'm not getting a lot of bass, but that is likely, at least partially, the speakers. I may upgrade them at some point, but, for now, this is great. Be aware, it does not come with a power brick, so you need to buy the one that it suggests in the listing. 12V 10A is about right. You need to be sure you have enough wattage to drive the amp. Anyway, if you don't need much and don't want to spend a lot, like me, you'll love this thing.

Pros - Low cost. Small size. No problems with connecting and Bluetooth pairing. Two screw holes for mounting. Cons - Doesn't include a power supply. Volume will depend on power supply voltage and amperage which can be confusing for some customers. No external Bluetooth antenna and range is somewhat limited - about 10' for clean connection to an iPhone in your pocket and about 20' for connection to a stationary iPad that is placed in an optimal position. Bass and Treble controls are swapped (how did they mix this up?). Fragile amplifier design as one channel blew out after 24 hours. Speaker connections require wire no bigger than about 18AWG.

Got this for my daughters gaming computer to help enhance the experience with the sound.. don’t be fooled by the size of this or the price! It’s impressively powerful! Nice clean sound , good base, very happy with it!!

Excellent sound but you have to adjust the tone controls for the best sound which is subjective. Blue tooth very easy to set up. No audible background noise.

Worked great out of the box, but on day 3 my right speaker would pulse every second and sounded like it may have blown. After switching a few different speaker leads to the right channel it was obvious the amp had actually failed as my right speaker operated fine omqhen connected to the R channel or other output devices I own. Glad some people had great experience, wish I could say the same.
