SFB Series(Smart Full Bridged)
The pioneer of a series developed by Hosun with breakthrough technology in performance for car audio systems. Its biggest feature is its multi-impedance function that allows it to operate between 1 to 2 ohms, besides that, the Power Control System technology ensures greater performance and safety.
SFB Smart amplifiers are latest and greatest intelligent full bridge amplifier, the SFB serie’s power supply is built stronger, heatsink is heavier, and the SFB smart serie’s feature intelligent low voltage technology protecting the amplifier from typical full bridge malfunction. The SFB series also runs cooler because of latest fan upgrades.
