Bluetooth Amplifier Board, 100W+100W Peak Output Power, 2.0 Channel DC:8-24V, Password Free Connect, BT 5.0 AMP Board for DIY Wireless Speakers Board

Don't let the size fool you. This little bluetooth amplifier works great. It is powering a set of Klipsch outdoor speakers and sound great. Bluetooth range is decent. Just try and not put alot of walls or objects between your Bluetooth source and the amplifier.

Excellent Sound and Build Quality

So I looked at several of these amp/bluetooth receivers all seemed very close in design and overall build quality. I choose this one based on its reviews and price under 20 us dollars delivered in one day wow! Spent about 30 minutes assembling and running a test using a lithium drill 18v battery. Powered it on and my phone saw it immediately and paired no issues. Opened Spotify and listened to several types of music and spoken word stations. Sound quality is on par with much more expensive gear. Using a set of Pyle 4ohm 200w speakers it drove them exceptionally well it wasn't coming close to 200 watts however the power supply was just a 2amp hour 18v battery. However it still pushed enough volume to be heard easily all through my home. I'm going to use this setup in my old truck 12v 5amp switched supply. It's good to remember even in the off position the Bluetooth circuit is continuously powered. Now I wouldn't expect this draw to kill an automotive battery quickly however left on over days between use it could. The initial test was very pleasing considering I have less than 50 dollars in the entire setup. Even at roughly 1/2 volume in the amp and the source at 100 percent it was loud enough to easily be heard over the road and truck noises while driving. So for this meager amount of money my thirty year old Ranger now has bluetooth radio, GPS, all the great things my phone can do. According to the specs given the speakers at full blast are receiving 40watts at 4ohms using the existing 12v circuit originally provided for a radio. Plenty of wattage to drive the Pyle 4ohm 200w rated speakers. What a time we live in back in the day I had a clarion head unit with 2 Kicker boxes by stillwater and door Kenwood pro series speakers along with a 200 watt amp driving the boxes and an 80w equalizer driving the door speakers I had more 1500 in this setup and it rocked inside a small pickup. Not saying this setup sounds that good or that loud. However this setup especially for the price is incredible especially considering all I get once paired to my phone. Anyway long review but if you want to replace an old system in your beater car or truck and not spend hundreds of dollars this is a great way to go. Takes very little understanding of electronics to assemble the biggest thing to keep in mind is the polarity of the amp when connecting the power and use 4ohm speakers to help get the most out of this little guy.

Pros: Very versatile product. Can be mounted anywhere. Easy to assemble and connect to any speaker. Connects with bluetooth immediately and a digital tone indicator. I do like the accessories that it comes with like power jack, knobs, screwdriver, screws and housing. Comes with or without an auxiliary jack. The power and sound it has is nice. No static noise that I have noticed. I will buy again. I have many ideas for this little gadget!Cons: It cuts off every once in a blue moon because I think it overheats but am not sure. Maybe there is a line spike in the household plug that resets it (it has overload protection I believe). All one has to do if this happens is disconnect from the power source for a couple of minutes then plug back in. Does not come with a power plug which I would like to see in the future. I bought a 24V cord. Don't turn it all the way up if your speakers can not handle it or the sound will be distorted and bad.

It was super easy to wire, 12v, connect two speakers, and then to the phone. The only thing visible is the on/off volume dial. I wanted to keep the car original, the old AM radio works but...come on? Now I just start the car, turn on the switch, it connect quickly to my radio with minimal startup noise, adjust the volume and go. In the future I plan on buying again but the bigger one with a subwoofer connection. This does not allow left/right adjustments nor fade front to back. If you are looking to keep the car radio, that may or may not work, this is the item.

I've actually bought a few of these and I've been using them on motorcycles. They make a fantastic upgrade over. Basically any stock system in a dresser or goldwing and allow for much more powerful speakers or even the ability to use high-powered transducers (and they shake whatever you're attaching to to make sound such as the fake gas tank on a goldwing)I'm glad they come with pigtails, but I really wish I could get this with some sort of terminals so I could have a cleaner install. It would also be amazing if I could get a version where the power/ volume knob is on a cable so I can tuck the box out of the way somewhere and make it watertight and only leave the knob exposed.

Update it died in 3 months with hardly any use unfortunately.... Bought another version from another site to try this time...Clean, balanced, no hiss, just wow.... Half way up it's captain insano!!!!!Powers on a m18 battery no problem and loads of clean output... Bought another one elsewhere on a popular bidding site nearly half the price I liked this one so much will use for back porch outdoor speakers

For the price a super amp easily replaced the amp in my speaker bar UTV.
