Bluetooth Power Amplifier Board with Subwoofer 2.1 Channel 50W x 2+100W DC 12V-24V Audio Power Amplifier Module for DIY Bluetooth Audio and Store Home Theater with Treble and Bass Control

Very nice little amp. It has a decent amount of power to drive an 8" sub with no distortion at decent levels. It is a Bluetooth amp and there are no instructions including in the package to instruct how to turn it on and off, this was problem for me, as it kept trying to sync with something. I finally had to move my phones away from it to get the amp to work. It comes in a semi kit form, thus the reason for the enclosed screwdriver. The top and bottom has to assembled with tiny screws, and the knobs installed. My problem was with the lack of no instructions and not knowing how to use the Bluetooth. I am using it as a sound bar amp whose amp decided it was time meet its demise. Overall great sound. Nice highs and deep bass. I am powering it with a 30-amp 12-volt power supply. Overall great value for the money. Hope it keeps on pushing for years!!

Liked so much I bought two.

Helped me fix an active subwoofer in which the internal amp died. It packs a lot of power you can adjust the frequency plus there 2 additional channels if I need them. Found a power adapter lying around and used it with this.

This little gadget is like a super sound system. I use this has a home theater system and make movies, games, music sound great. For the price you can’t beat this little thing it’s not perfect but it sure bring the power like the expensive stuff.

Does what it's supposed to do.
