Excellent BT transmission and quality!
I recently purchased this Bluetooth Transmitter, and I couldn’t be happier with my decision! If you’re considering building a stereo system, this product is a top-notch choice that won’t disappoint.First off, the signal transmission is outstanding. Iâve tested it from distances of up to 175 feet, and the connection remains strong without any dropoutsâtruly impressive! It’s perfect for those looking to enjoy music throughout a large space without the hassle of wires.I paired it with a 12-volt, 8 amp-hour battery and an Infinity speaker, and it has been playing beautifully for over 60 hours on and off! The efficiency of this transmitter is remarkable; it hardly draws any power, which means I havenât had to charge the battery yet.Overall, I highly recommend the Woozie Bluetooth Transmitter to anyone looking to enhance their audio experience. The quality is excellent, and Iâm eager to purchase more. I really hope they stick with the current design, as itâs clearly performing wonderfully!

Good buy easy to install
Works good, easy to set up. No app to down load, but I think the Chinese are messing with us.

Excellent Little Amp for DIY Bluetooth Projects
Excellent Little Amp for DIY Bluetooth ProjectsI used the ZK-1002T Bluetooth amp in a custom portable speaker box powered by an 18V battery, and it absolutely delivered. For such a compact unit, it puts out plenty of clean powerâmore than enough to drive my 6.5â marine speakers with solid volume and clarity.Bluetooth pairing is quick and reliable, and the sound quality is surprisingly good, especially for the price. I also like that it supports both Bluetooth and aux input. The compact size made it easy to mount inside the case without overheating or needing extra ventilation.Just be aware that there are no instructions included, so if youâre new to wiring or amps, you may need to reference some diagrams online. But for DIYers who know their way around a project, this amp is a solid choice.Highly recommend for anyone building a battery-powered sound system or portable speaker setup.

Outstanding small Chip amp that packs a punch.
Bluetooth connectivity:It is very good range without adding an antenna. Size:Love the size of this chip amp. Running on 24 volts gets amazing sound quality. Sound quality:To be able to adjust both Bass and Treble is a huge plus for sound quality.Â

Excellent Amp for Custom Builds
I joined a Facebook group for building speakers, and these little amplifiers were highly recommended. I completely concur. This little thing is awesome! The Bluetooth connectivity is great! It is very easy to connect and has good range. I am using a full range, medium quality marine speaker and hooking up to an 18-volt battery (actually pushes 20.2v). If you run this amp with the volume all the way up, it will be distorted. I turn the volume to around the halfway point on the amp, adjust my bass and treble accordingly (a little more than the mid-way point for each), and then just control my volume from whatever device I am playing the audio from. This thing is excellent for the price, and it easily competes with some of the expensive store-bought systems. It is a definite bonus that it comes with the plug, and it includes a mini screwdriver for your wire terminations. The attached photo is not the finished build, but I had to test it out!

Versatile amp with left/right channels- No subwoofer channel but has good bass response
Works as designed. NOTE – the product title is correct “ZK-1002T Bluetooth 5.0 Amplifier Board 2.0 200W HiFi Subwoofer Audio AMP with Treble and Bass Control. This is a 2.0 board. Further down the Amazon listing there is a different description “Subwoofer Audio Amplifier Board: 100W+100W Bluetooth 5.0 wireless connection, Bluetooth+AUX audio input, 2.1 channel stereo output” Nah, this does not have subwoofer output just left and right (2.0 not 2.1). I like the build quality – it looks to be put together well, and it works nicely with a small bluetooth speaker system. I have run it on 11.9VDC and 19.4VDC, works well on either.
