Features:
This model uses 2 sets of automatic boost systems, that is, regardless of whether the power supply is 12V or 18V, the system will automatically rise to 24V to power the amplifier, so it can get more power under the power of a single battery. It is often used in outdoor trolley cases and DIY subwoofers. Wait for a switch on the motherboard to switch between subwoofer mode or full tone mode. If you use 2 Allegro, one for full tone and the other for subwoofer, the effect is really cool! There are independent total gain and subwoofer gain next to the corresponding switch The adjustment is more user-friendly and more suitable for free combination! Gain is the meaning of volume adjustment
