Alpine PWV-SB12

Overview: The Alpine PWV-SB12 is a compact powered 12″ subwoofer that can produce extremely low bass from a small enclosure that can fit in tight spaces, including behind truck seats. The sealed enclosure is constructed of double-braced MDF and covered in attractive black carpeting.

Power: The PWV-SB12 features a built-in Class-D amplifier that can power the dual voice coil driver with 400 watts RMS (800W peak).

Note: No wiring is included with the powered subwoofer. An 8 ga. amp wiring kit is recommended and must be purchased separately.
Speaker Level Input: The Alpine powered subwoofer can accept low-level or speaker-level input signals, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs. Two RCA-to-speaker wire adapters are included for connecting high-level signals.

Auto Turn-on: If using the speaker level input, an automatic circuit turns the amplifier on when it senses an input signal. When using the line level inputs you must also use a remote turn on lead.

Controls & Controls: All of the PWV-SB12 connections and controls are located on a control panel on one side of the enclosure:

• Turn-On Mode: A 3-way switch determines the turn-on method; DC, REM (Hi-level), REM (Lo-level)
• Gain: rotary control; range Min-Max.
• Low Pass Filter: rotary control; frequency cutoff range: 50-200 Hz
• Phase: two position switch; 0° or 180°
• Connections:
  • Terminal Block: A removable terminal block provides the power, ground, and remote turn-on inputs, accepting up to 4-gauge wire (power/ground) and 8-gauge wire (turn-on).
  • RCA: Left and right RCA jacks can accept low-level signals ranging from 200 mV to 2 V, and speaker-level signals ranging from 500 mV to 10 V.
  • Remote Control: An RJ-14 jack lets you connect an optional Alpine RUX-KNOB.2 remote level control (sold separately) for adjusting the bass level separate from your main speakers. The remote has a range of 0 (max) to -20 dB (min).
  • USB-C: Used for updating the firmware on the PWV-SB12. The USB-C port cannot be used for playing audio or powering USB devices.

Indicators:

• Power: A power LED will light Blue when the amplified enclosure is powered on and operating nominally.
• Protect: A protect LED will light Red if a problem is detected, including a short circuit, high temperature, and over-voltage on the power input.
