Quite surprised how good it sounds and great to have controls for sub woofer and Bluetooth. Can't fault for now but will see how long it lasts. 5 stars for now ;) Review: Amazing bit of kit, great sound. Real powerfull. Fully reccomend - I have already bought one of these Bluetooth amps with the 2x220w speaker and 1x350w subwoofer outputs. Just on the off chance that I could wire up a couple of my Dewalt batteries and use up an old sub and speakers to make a boombox. I was so blown away by how loud and good the sound was I had to build another a bit smaller and portable so I could use it more, so I went for this 2x50w speaker and 100w sub output with 1 battery at 18v. This was the outcome in the video. Once again well powerfull and amazing sound. ## Features - Adopt imported TPA3116D2 chips, with excellent power amplifier effect. - The distortion is less than 0.1% even at high power output. modulation frequency up to 1.2MHZ, built-in LC filter capacitor to make the vocals clearer. - Input Voltage: DC 12V-24V; Max Power Output: 50W*2（R&L）+100W(Subwoofer); Input Method: Bluetooth & AUX; Channel: 2.1 CH Stereo Output; Output Impedance：4-8Ω; Bluetooth Version: BT 5.0. - Bluetooth 5.0 version, Transmission Distance Is Farther.
