I have a 2009 Ford F150 Super Crew and this bass box and amp is all you need. This bumps the hell out of my cab and fits perfectly under the rear 1/3 seat. Below I've linked to all the stuff you'll need.
The TS-SWX251 is designed for compact spaces, such as behind a pick-up seat, in an SUV or minivan cargo area, or under rear seats..

Pioneer's GM-D7500M mono Class-D amplifier delivers 200 watts x 1 at 4 ohms, or 400 watts x 1 at 2 ohms. That's enough to provide your subwoofer with tight, efficient bass. Speaking of efficiency, the GM-D7500M's Class-D design means less energy is wasted, so you gain more power with a smaller profile. A built-in crossover and bass boost circuit let you dial in the bass content to suit your vehicle.
GM-D7500M Specs
Pioneer's TS-SWX251 10-inch flat subwoofer with enclosure is designed for compact spaces, such as behind a pick-up seat, in an SUV or minivan cargo area, or under rear seats. A lay-flat design and down firing sub deliver serious low-end in even the most cramped installation. Maximum power handling 800 watts.
The TS-SWX251 is designed for compact spaces, such as behind a pick-up seat, in an SUV or minivan cargo area, or under rear seats..
The TS-SWX251 radiates bass with superior efficiency for rich, deep sound regardless of the installation.
Compact space-saving dimensions make it easy to install the subwoofer in a variety of trucks.
Thanks to its innovative enclosure design, the TS-SWX251 enclosure can be installed freely in the cabin or luggage area for optimal utilization of space. The compact space-saving dimensions also make it easy to install the subwoofer in a variety of trucks- standard-cab, extended-cab, or crew-cab.
Enjoy deep big bass from a small enclosure. In order to create a subwoofer that is three and a quarter inches deep, Pioneer had to develop revolutionary subwoofer technology. A traditional subwoofer uses the spider design to keep the voice coil of the speaker aligned while it moves. This type of set-up can become soft over time degrading the subwoofer's performance. Pioneer created a patent-pending air suspension system that locks air between a main cone and a drive cone. The cones move together in unison, with the locked-in air behaving like a spring. The dual-cone structure is a spider-less design that maintains better sound linearity, and reliability even after many of hours of hard use. The pressure from the trapped air results in a consistent bass response across a wide frequency range. The result is a tight, precise movement with powerful and clean bass output.
Angled Push Terminals
Traditional subwoofer terminals are mounted horizontally or vertically. These mounts force wires to be bent to fit which can be difficult if low gauge high performance wires are used. The Pioneer shallow subwoofer's patent-pending, angled push terminals make it easy to connect speaker wires. The straighter connection saves space and makes installation easier.
Downfiring Subwoofer Technology
By directing the subwoofer diaphragm downward, the TS-SWX251 radiates bass with superior efficiency for richer, deeper low-frequency sound regardless of the enclosure's installed position.

Pioneer GM-D7500M Class-D Mono Amplifier with 800 Watts Max. Power
 | Pioneer GM Digital Series AmplifiersA Commanding PerformanceTraditional analog amplifier designs are electrically and thermally inefficient--converting as little as 30% of their electrical power into acoustical energy, while the rest is wasted as heat. The dispersion of this excess heat requires large and heavy heatsinks, increasing the size and reducing the installation flexibility of a traditional analog amplifier. Pioneer's GM Digital amplifiers utilize Class-D amplifier technology to produce a compact, high-power amplifier that converts as much as 70% of its input power to sound. Serious Sound. Small Space. The compact size of the GM digital amplifiers enables them to be installed in more places in your vehicle. If you want your system to be heard and not seen, Pioneer's GM digital series is the perfect choice, as it's both small and powerful. The advanced circuitry of the GM-7500M model for instance, is 45 percent smaller than its analog counterparts, increasing your installation options in tight spaces. Now you can enjoy superior audio amplification and installation flexibility from a compact product. Bridge Your System With Digital The GM Digital line of amplifiers has already earned an impressive reputation with Pioneer retailers and customers alike. This year, for the first time, a full-range solution joins the digital line-up in the form of the GM-D9500F. You can now harness the compact, powerful qualities of digital design to create a full-range, fully digital system. |
