Want to restore the bass in your music without a lot of boxes and loud booming? Maybe a compact powered subwoofer can do the job for you, and bring some fun back to your ride. Getting a single, all-in-one unit instead of having to deal with a separate sub, amp, and enclosure will save you cargo space and simplify your wiring requirements.

Sound Ordnance's new B-8PTD powered subwoofer is small enough to fit under most car seats (or in an out-of-the-way location in the cab of a truck), but powerful enough to pump out enough bass to keep up with almost any factory or aftermarket stereo. This little workhorse will surprise you with its impressive bass and its ability to mesh perfectly with the rest of your system.

We took one apart to show you the separate components and how they fit together into a unified subwoofer system. Click on the yellow boxes to read more.
