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!

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

It's one powerful little work horse . It drives everything I have connected to it . Even 15 inch pa speakers. Super clean sound seperates highs and lows Will be recommending to my friends . You will want to have a 24 volt power supply to get it up to it potential output. Very much worth the price.

Almost perfect. It took me a while to engineer a mounting box for this thing because the posts are very short. This would be exceptional if they extended the mounting threads about another 3/16 = 1/4 of an inch so it could fit through a common outdoor metal box thickness.

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.

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.

I purchased two of these. The first one showed no signs of Bluetooth even though I was sure I was giving it power. None of the devices saw a Bluetooth connection to it. It almost appeared DOA dead on arrival. The second one was exactly the same.Sad I was really hoping this would work. Buyer beware

Great sound! LOUD!
