Compact powered subwoofer for tight vehicle spaces

The Rockford Fosgate PS-8 is an 8-inch amplified subwoofer designed to fit beneath a seat. Its built-in Class-D amplifier delivers 150 watts RMS and the shallow enclosure allows installation where full-size boxes cannot go.

Closed-loop enclosure

A closed-loop design aligns woofer, amplifier and enclosure for consistent output. High- and low-level inputs accept factory or aftermarket sources, while a three-way turn-on selects remote, DC-offset or signal-sense activation. Included power, ground, turn-on leads and mounting hardware simplify the install.

12 dB crossover and phase control set

The adjustable 12 dB per octave crossover and 0 or 180 degree phase switch shape how the sub blends with existing speakers. Onboard Punch EQ and the wired remote bass controller let you tune impact from the driver seat. Thermal, short-circuit and reverse-polarity protection guard the amplifier during extended use.

Questions about this item

What does the built-in 150 W RMS Class-D amplifier power and how is the crossover set?

The internal amplifier drives the 8" woofer and its crossover is adjustable at 12 dB per octave so you can match the roll-off to your front speakers.

What are the exact dimensions and clearances needed to mount this enclosure under a seat?

The box measures 14-1/2" wide, 9-1/2" deep and 3-3/8" high; verify your seat rails allow at least that footprint and height before ordering.

How do you connect the three turn-on options and which wiring mistake causes no output?

Choose remote, DC offset or signal-sense turn-on via the 3-way switch; forgetting to connect the selected turn-on wire leaves the amp in standby with no bass.
