Our take on the Sound Ordnance B-8PT by Crutchfield's Dominic DeVito
The Sound Ordnance B-8PT powered subwoofer turns the hard-to-fit spots in your vehicle into potent bass bastions, adding warmth and punch to your favorite music. You can fit this compact low-frequency factory under your car seat or in an out-of-the-way location in the cab of your truck. Preamp- and speaker-level inputs allow convenient connection to just about any system, plus you can tweak the phase control, bass boost, and low-pass crossover for maximum firepower in your vehicle. A wired remote lets you take command of your bass from the driver's seat.
The B-8PT's built-in amplifier sends 120 watts RMS to the 8" subwoofer, adding high-impact low notes that'll fortify your music. The Sound Ordnance logo means you'll get more than tremendous value and reliable performance the B-8PT is reinforced with a 3-year warranty so you can add it to your system with confidence.
Great subwoofer in a nicely sized package.
