"Fit perfectly and worked exactly as expected — support was excellent."
Rockford Fosgate P3SD2-8
Upgrade Your Vehicle With Confidence. This Is Built to Fit, Perform, and Last
Punch 8" P3S Shallow 2-Ohm DVC Subwoofer
If you love deep, hitting bass but drive a truck, a compact car, or a vehicle with tight trunk space, you’ve probably been told you just don't have the room for a real subwoofer. The Rockford Fosgate P3SD2-8 is built specifically to prove that wrong.
Instead of forcing you to choose between having a trunk or having great sound, this 8-inch shallow-mount subwoofer is engineered to fit into tight spaces where a traditional, bulky woofer simply can’t. Rockford Fosgate compressed the physical size of the motor structure without sacrificing the "Punch" they are famous for. Featuring Dual 2-Ohm voice coils, it gives you the wiring flexibility to match your amplifier perfectly, pulling a solid 150 Watts RMS of clean, impactful low-end right from behind your seat or under a cargo floor. It's real bass, tailored for real-world space.
Product Highlights
-
Big Bass, Tiny Footprint: Specially designed shallow motor assembly allows you to drop this into tight enclosures, making it the perfect upgrade for trucks, compact sedans, and SUVs with limited space.
-
Built for Wiring Flexibility: The Dual 2-Ohm Voice Coil (DVC) design lets you configure your wiring setup to get the absolute most power and efficiency out of your amplifier.
-
Premium Construction: An anodized aluminum cone and dustcap keep the woofer incredibly rigid and lightweight, meaning your bass stays clean and distortion-free even when you crank the volume.
-
Stays Cool Under Pressure: The StampCast basket features integrated spider venting to continuously flow air across the voice coils, protecting your investment during long, hot road trips.
Key Features
-
M-Roll Santoprene™ Surround: This specialized rubber surround allows for maximum cone movement (excursion) while resisting the wear and tear of daily environmental exposure.
-
Enclosure Versatility: Optimized to perform beautifully whether you prefer the tight, accurate punch of a sealed box or the extra volume of a vented enclosure.
-
Dual Linear Spiders: Features embedded 16 AWG tinsel leads to securely guide the cone's movement, ensuring long-term reliability and preventing annoying mechanical noise.
-
Diamond Cut Trim Ring: Includes a cast aluminum trim ring that gives your install a clean, high-end look right out of the box, with the option to add a protective grille later.
