Rockford Fosgate engineered Power Series subs for ultimate high-power, high-volume bass. So whether you're building a system for serious competition or just to satisfy your appetite for great bass, these subs deliver colossal low-frequency reproduction that's as real as it gets.

Crowd-drawing bass beats
The Power Series T0D412 12" subwoofer features a responsive paper cone that's reinforced with the same Kevlar® fibers used in bulletproof vests — a hard anodized aluminum dust cap covers and protects the entire cone, showcasing the glossy Rockford Fosgate logo. The result? You get classic warm bass from a cone that's virtually indestructible. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

Extended excursion for more bass
This T0 sub is housed in a hefty cast aluminum frame that provides a stable platform for extreme cone excursion, while an extended pole piece and bumped backplate allow the sub to hit deeper lows without "bottoming out." Special venting in the frame keeps the aluminum voice coils cool through heavy use for consistent bass performance over time.

Fuse-protected impedance selection
Rockford Fosgate outfits Power Series subs with their unique SWIFT™ terminals, which lets you build exactly the system you want — high-power or multi-sub — without complicated wiring. Just rotate the impedance selection jumper to safely choose between 2 or 8 ohms. The jumper is also fused to protect your sub from accidental overload. If you're thinking about adding another sub down the line, this sub simplifies reconfiguring your system. These subs work equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.
