Sundown Audio SA-6.5SW 6.5" 300w RMS Car Audio Subwoofer DVC 4-Ohm SA Series Sub

Description:

The SA-6.5SW was created to achieve extremely high performance with less than 4” of mounting depth. Sundown uses a solid-pole design, allowing the back plate to rest against the back wall of the enclosure to reduce the mounting depth requirements even more. Twenty millimeters of mechanical excursion means surprisingly deep bass out of this mighty 6.5” sub!
