Power T3 19-inch superwoofer
Rockford Fosgate rates the T3S1-19 at 3000 watts RMS and 6000 watts max into a single 1-ohm voice coil. Sensitivity is 91 dB (1 W/1 m) with Fs near 27 Hz and Xmax of 34 mm. This driver is built for competition-style vented systems that can supply serious current and a large box—not for sealed trunk builds or compact daily-driver enclosures.
Enclosure and fitment
Recommended vented volume is 8.0 cubic feet (226.5 L). Sealed enclosures are not recommended. Mounting depth is 15.62 inches (396 mm) with a 17.72-inch (440 mm) cutout that needs a wide baffle. Woofer displacement is about 0.339 cubic feet. A 4 AWG compression terminal accepts heavy speaker wire. Shipping weight is over 100 pounds, so plan bracing and two-person handling.
Amplifier and install reality
Plan a mono amplifier stable at 1 ohm with appropriate alternator, battery, and wiring upgrades. An enclosure, amplifier, and wiring kit are sold separately. Confirm vehicle space for a 19-inch cutout and 15.62-inch depth before ordering—this is a specialty competition driver, not a simple drop-in trunk woofer for everyday street use. Expect custom fabrication for any vehicle that can house this driver. Plan electrical upgrades early. in the build.
