JBL S2-1024 (Open Box, Complete)

JBL believes sound quality should never be compromised. And Series III subwoofers make sure you don't have to compromise flexibility, either. That's because the high-performance, step-up subwoofers feature SSI (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance—2 or 4 ohms—for your system, And an oversized voice coil handles more power than common voice coils.

Key Features:

SSI (Selectable Smart Impedance)


Most car audio system designs call for 2- or 4-ohm impedance. Series III subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.

Oversized voice coil


The two-inch voice coil proves you don't have to be a heavyweight to pack a serious punch. It handles more power than conventional voice coils, yet it's lighter than three-inch voice coils. It strikes the perfect balance between thermal power handling and low mass.
