Do you want to add some bass to your ride without losing storage space? Take a look at the Kicker PH12 powered subwoofer — its heavy-duty enclosure is slim enough to fit in many locations and powerful enough to help fill in the low end of your sound system.

A perfect match
It can be tough matching subs, amps, and enclosures together. Kicker's taken the guesswork out of the process by matching a 90-watt RMS amplifier with a 12" subwoofer, and housing them together in a rugged, compact box. This way, you won't have to waste time juggling specs — just focus on enjoying your bass.

Out in a jiffy
A quick-connect power harness and removable straps make it easy to pull this sub out of your vehicle, so you can get some storage space back in a pinch. The enclosure is only 11" deep so it'll fit in a variety of spaces, while the carpet covering will protect the enclosure and your vehicle against scratches and dents.

Product Highlights:

  • powered 12" subwoofer enclosure
  • Class D amplifier (90 watts RMS)
  • remote bass-level control (with 20-foot cable) included
  • variable bass boost (0-6 dB at 40 Hz)

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

Features

Amplifier: The power output from the built-in class-D amplifier is 90 watts RMS @ 14.4 volts with no more than 1% THD (100 watts RMS @ 14.4 volts and 10% THD).

Signal Input: The signal input wires on the included harness can be used with a speaker level or line level signal. Standard speaker wire is used in the harness, so an RCA to speaker wire adapter is needed when using a line level signal (item number 20609ZISL, sold separately).

Low Pass Crossover: The amplifier's low pass crossover point is continuously variable from 50 to 120 Hz; the crossover slope is 12 dB per octave.

Subsonic Filter: In addition to the low pass crossover, the PH12 features a 24 dB/octave subsonic filter fixed at 25 Hz. Ultra-low frequencies that cannot be reproduced by a subwoofer do not become sound, but unnecessary oscillations that cause distortion. These frequencies also waste amplifier power and can damage the speaker. The built-in subsonic filter removes the frequencies below 25 Hz to improve the sound quality by eliminating harmful distortion.

Bass Boost: The bass boost circuit provides a variable (0-6 dB) signal boost centered at 40 Hz.

Status Indicator Light: There is a status indicator LED on the control panel on the left side of the enclosure; it lights green to indicate that the amplifier is turned on and operating normally and lights Red to indicate the amplifier's protection circuitry has been activated.

Remote Bass Level Control: The included remote bass level control lets you adjust the output level of the amplifier from anywhere in the vehicle. A 20' cable is included and when it's plugged in, the gain control on the side of the enclosure is bypassed. The remote bass level control can be mounted under the dash with the included mounting hardware, it has the following dimensions:

  • Width: 2.215"
  • Height: 1.193"
  • Depth: 1.718" (3.076" including the knob and cable)

Controls: All the PH12's controls and connections are located on the left side:

  • Auto Turn-On: two position switch; choose +12V (amp turns on when +12 volts is applied to the remote turn-on wire) or DC Offset (amp turns on when a 6 volt surge is detected from a speaker-level source on the signal inputs; in this mode the amp's remote turn-on wire acts as a +12 volt output to turn on another component)
  • Input Level: two position switch; choose Hi when using a speaker level input, Lo when using a line level input
  • Phase: two position switch, the sub's phase can be easily inverted; 0° or 180°
  • Gain: rotary knob; continuously variable from 125mV to 5V when the Input Level switch is set to Lo, 250mV-10V when the Input Level switch is set to Hi
  • X-Over Frequency: rotary knob; set the low pass x-over point; continuously variable from 50 Hz to 120 Hz
  • Bass Boost: rotary knob; continuously variable from 0 to +6 dB

Connections:

  • Remote Bass: 3.5mm mini-jack for use with the included remote bass level control
  • Fuse: a single 7.5 amp ATO style fuse protects the amplifier
  • Wiring Input: Molex plug for use with the included power/ground/remote turn-on/signal input harness; the wire length varies by function:
    • Ground: 18"
    • Signal Input: 16'
    • Power: 19'
    • Remote Turn-on: 20'
