These M1 Series M1D4-8 8" subs feature a rugged, removable grille that looks great and stands up to blistering sunlight and damaging moisture. Underneath the UV-stable shell and durable Santoprene rubber surround, you'll find an injection-molded mineral-filled polypropylene cone that's treated with UV inhibitors, plus moisture- and tear-resistant synthetic fiber blend spider.



The 2-position VersaSwitch lets you set up each sub for 2-ohm or 8-ohm impedance with a simple flip of the switch. Rockford Fosgate's corrosion-resistant, spring-loaded push terminals, and flexible, insulated silicone lead wire will stand up to the elements, whether you're on open water or tied up at the marina. These Element Ready subs won't miss a beat - and neither will you.
