ZK-1002T 2.0 Channel Bluetooth 5.0 Amplifier Board 200W HiFi Subwoofer Audio AMP with Treble and Bass Control BT and AUX Inputs, DC 12-24V 2.0 Channel Stereo AMP Module for DIY Speakers

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. I’ve tested it from distances of up to 175 feet, and the connection remains strong without any dropouts—truly 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 haven’t 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 I’m eager to purchase more. I really hope they stick with the current design, as it’s clearly performing wonderfully!

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.

Cheap, compact, and packs a serious punch. This pushes a pair of boat speakers super clear, with great treble and bass. highly recommend!

I primarily bought this to test speakers that I wanted to install into my vehicle. The sound it outputs doesn't include a lot of electrical noise, and it can output a good amount of power. One thing to note is that to obtain the full 100W of power, you will need to give it 24V. It will not achieve this at 9-12V of input. I didn't have an aux cord to test on this, but Bluetooth audio isn't the best quality and compression noticeably hurts the sound quality of the audio stream. This would be a cool device to drive desk speakers and make good use of the power they are capable of handling.

Very easy to install, work well these are small so they would fit almost anywhere. As for the quality, I have only had them about a week so I will update later.

Sound Quality is great…..small package, big power

At half volume speakers start to clip and cut out, overloading this unit. I doubt it's actually 200 watts

Great sound! LOUD!
