Rockford Fosgate Prime Series R2SD4-12 shallow 12" R2 4-Ohm DVC Subwoofer

Rockford Fosgate R2SD4-12 Prime R2 Series 12" shallow mount subwoofer with dual 4-ohm voice coils

Rockford Fosgate's Prime R2 shallow-mount subs deliver satisfying bass even in smaller cars where space is tight. A special elevated motor structure lets these low-profile subs work in extremely compact enclosures, while still handling plenty of power.

The R2SD4-12 sub-features a 12" mica-injected polypropylene cone that works with a high-density poly-foam surround to punch out fat, deep notes. This shallow-mount workhorse will handle up to 250 watts RMS, with a mounting depth of only 3-5/8". Rockford Fosgate stitches the tinsel leads that carry the signal to the voice coils directly into the cone, so they'll hang tough through heavy use. The stamped solid-steel frame offers the same venting found in standard-mount Rockford Fosgate subs to keep this sub running cool.

Dual 4-ohm voice coils allow you to wire this sub for 2- or 8-ohm impedance, giving you more flexibility in setting up your system. Rockford Fosgate optimizes this Prime sub for both sealed and ported enclosures so you can choose the type of bass you want in your ride.
