Scion XB Stereo Upgrade: Amp, Subwoofer and Enclosures XBoom Box, Part 1 of 2 From "Tricked Out" episode DTRK-313

This Scion xB, already tricked out with a sliding rag-roof, gets the thump treatment with amplifier mega-wattage, subwoofer and rear-firing speaker pods. You'll definitely hear it coming.

In this project, Tricked Out host Andrew Totolos upgrades the stereo of a Scion XB with a show-worthy amp and subwoofer kit, plus a set of custom mounted rear firing speaker pods normally used on wakeboard boats. These mega-stereo upgrades are going to turn this XB into a portable outdoor party machine.

Andrew begins the installation of the upgraded sound system as he installs a new amp and sub enclosure in the area where the spare tire used to live.

DIY Difficulty Rating for This Project: We gave this a difficulty rating of 4 on a 5-point intermediate-level scale. The sub and amp part of the project is pretty straightforward, but the pods are going to require some fabrication and light welding.

DIY Difficulty Rating for This Project: We gave this a difficulty rating of a full 5 on a 5-point intermediate-level scale. Make no mistake, for this modification you've got to be willing to cut a giant hole in the roof of your car--so this project may not be for the feint of heart. But if you're ready to take on a fairly daring conversion upgrade, we'll take you through the basic steps.

The Project Car: Scion xB

The XB is a bit of a departure from our usual fare on Tricked Out. Essentially a direct import of the JDM Toyota BB, the Scion xB is a unique looking ride that combines distinctive lines with a huge and comfortable interior, all in a compact and agile package. With 105 stock horsepower, the xB isn't going to win any races, but the retro-boxy lines and the practicality of this little truck give it a high ranking on the cool-quotient meter.

This particular Scion xB is already hard to miss with red tribal flame graphics running along the sides. It sits on 7-spoked factory alloy wheels with painted brake calipers underneath. Clear tails and a chrome exhaust tip dress up the rear.

Inside, a carpeted subwoofer box fortifies the tunes while a carbon-look shift knob and upgraded pedals provide an extra bit of flash in the cockpit.

Under the hood, cold air intake improves both looks and performance.

This particular xB has already been the subject of one Tricked Out project, namely converting it to an open air cruiser by installing a giant sliding rag roof. Those mods were documented in Tricked Out, episode 310.
