The 8-inch woofer is integrated into a specially compact housing designed to produce minimal distortion and great bass. The BassPro SL2 generates hardly any heat and consumes little energy from the car system.
Its individual switching technology protects the 200 mm woofer in the BassPro SL2 auto subwoofer set and always produces perfectly rich sound even at different output powers. It also has line and high inputs.
Active JBL subwoofer amplifier: A small but powerful 125-W RMS mono 1-channel JBL Class D digital amplifier with a fully variable crossover and a built-in bass EQ – a truly powerful solution.
