About the Rockford Fosgate T215D2
What do you get when you combine high quality materials, state-of-the-art engineering, and a liberal dose of Rockford Fosgate's famous bass fanaticism? The answer: Power Stage 2 subwoofers. Ideally suited for use with Power Series amps, these woofers handle incredible power levels — up to 2,000 watts peak.
The mind-blowing 304-ounce magnet structure is triple stacked, and the huge 4" voice coils were born to handle big power. The aluminum parabolic cone with its high-excursion rubber surround hits quickly and accurately. Spider venting keeps the woofer cool even when you run it long and hard.
The T215D2 15" subwoofer works best in a vented enclosure. The dual 2-ohm design lets you wire for high output or a multiple woofer setup.
Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

Features
Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice coils that offer flexibility in wiring. When the voice coils are wired in parallel with each other, the woofer presents a 1-ohm mono load. When the voice coils are wired in series with each other, the woofer presents a 4-ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 2-ohm load.
Woofer: The aluminum parabolic woofer cone is lightweight and extremely strong, giving the woofer very high power handling, low distortion, and superior bass response.
High Excursion Thermo-Rubber Surround: The use of a tall/skinny high excursion thermo-rubber surround allows for linear cone travel on a high excursion driver without reducing cone area.
Parabolic Triangular Cone Geometry Support System: By bonding an aluminum parabolic dust cap of equivalent size to the cone body, a balanced triangular structure is created. This system reduces piston flex and eliminates cone distortion.
Mirror Image Symmetrical Spiders: Dual-opposing spiders offer superior mechanical stability during high excursions, while maintaining linear travel.
Spider Support Ring: This integrated ring increases the bonding surface area between the voice coil former and spider, establishing a stronger joint. The result is increased mechanical power handling under high power/high excursion situations.
Anodized Aluminum Voice Coil Former: Aluminum voice coil formers offer superior heat dissipation over other commonly used materials. The hard-anodized finish increases the former strength. These two factors combine to improve the overall power handling characteristics of the subwoofer.
Precision Cast Aluminum Alloy Basket: A two-piece "basket in a bucket" design adds rigidity and eliminates multiple acoustic resonances. Additionally, the large aluminum mass helps reduce voice coil former temperature and increase power handling.
Triple Stacked Magnet Motor Assembly: The stacked magnet assembly is used to create a powerful linear motor with increased excursion capability for superior bass output.
Slot-Loaded Spring Terminals: The proprietary, slot-loaded spring terminals will accept pin connectors and up to 8-gauge bare wire.
Concealing Ring: Once the subwoofer is mounted, the metal concealing ring can be installed to hide the mounting screws, giving the subwoofer a finished look.
Enclosure Compatibility
Recommended Vented Enclosures: Rockford Fosgate recommends mounting the woofer in a vented enclosure with an internal volume of between 2.25 cu/ft. and 3.25 cu/ft. with an ideal volume of 2.75 cu/ft. One 6" port is recommended at the following lengths for each size enclosure:
| Box Size | Box Volume | Port Length |
|---|---|---|
| Minimum | 2.25 cu/ft. | 23" |
| Recommended | 2.75 cu/ft. | 17" |
| Maximum | 3.25 cu/ft. | 14.5" |

I use to have one of these in my car, it was awesome. Besides that i cost alot of money it was a good investment i believe. It made my gas lid open up when i had it cranked, lol. So theres no power issues that you have to worry about. The only thing is the cost, other then that, fantastic subs.
