I'm very satisfied with this inbuilt Bluetooth amplifier. the product is unbelievable and it meets my expectations very well & the sound quality is extremely good at this range of amplifier. Bluetooth connectivity is also very soft it connects automatically within a half second after once u connect it. great value for money product. i recommend highly this product. Thank you Banggood.

Q: Is the main volume the volume for subwoofer too, or is subwoofer volume full independent from main volume? (Is the subwoofer volume increased and decreased with the main volume after setting the right volume with subwoofer volume?)

samx07 yes subwoofer volume will increase & decrease with main volume of amplifier
