JBL SUBBP12AM Ported Powered Subwoofer w/ 12" Sub and 150-Watt Amp

Highlights Powered subwoofer enclosure 12" sub with polypropylene cone Built-in 150 watt RMS amplifier (450 watts peak) Remote bass-level control included Speaker- and line-level inputs 8-gauge amp wiring kit required (sold separately) Variable low-pass crossover (40-200 Hz, 12 dB/octave) Variable bass boost (0-12 dB at 45 Hz) Phase switch (0°, 180°) Frequency response: 35-120 Hz Fuse rating: 25A Dimensions: 22-3/8"W x 14-5/8"H x 11-7/8"D1 x 9-1/8"D2 Warranty: 1 year Features Amplifier: The power output from the built-in amplifier is 150 watts RMS (450 watts max). The amplifier is counter sunk into the back panel of the enclosure (the heat sink fins protrude approximately 3/8"). Signal Input: The amplifier has both speaker level (harness) and line level (RCA) inputs. The input sensitivity range is 50mV-4V for the line inputs and 400mV-16V for the speaker inputs. Crossover: The amplifier's low pass crossover point is continuously variable from 40 to 200 Hz; the crossover slope is 12 dB/octave. Bass Boost: The bass boost circuit provides a variable (0-12 dB) signal boost centered at 45 Hz. Status LEDs: There are two status indicator LEDs on the amplifier. A green LED lights to indicate the amplifier is turned on and operating normally. A red LED lights to indicate the amplifier's protection circuitry has been activated. The protection circuit activates and the amplifier shuts down when the input voltage (power) is too high or too low, when the amp overheats, and when there is a short between the amp and subwoofer.
