Overview: The ACS112LG-TW1 PowerWedge+ is a compact powered
subwoofer, useful in vehicles with limited space. The sealed enclosure is loaded
with one 12TW1-0.25 12" low impedance subwoofer (0.25Ω) and a 400 watt
RMS class-D amplifier. The amp uses JL Audio's exclusive DCD amplifier technology,
combining direct power conversion (no conventional switching power supply) with an
ultra-high current output section. The result is an efficient design (91-94%) with
very little heat generated.
Enclosure Design: The enclosure features MDF (medium-density
fiberboard), constructed using CNC woodworking equipment, and covered with
high-grade automotive carpeting. The driver is protected by a black steel-mesh
Power/Ground Plug: The power, ground, and remote turn-on wires
attach to a removable terminal block; easily unplugged so the subwoofer can be removed
when you need more storage space. Each terminal is a screw clamp that will accept up to
8 gauge wire (minimum 8 gauge power and ground recommend).
Audio Inputs: The amplifier section will accept either a line
level (RCA) or speaker level signal. A 12" speaker level input harness is
Remote Level Control: An optional RBC-1 wired
Remote Bass Control (item number
136RBC1, sold separately) allows bass level adjustment from the front of your
- Input Sensitivity: rotary control; variable from 70 mV
to 1.4 V for the RCA inputs and 280 mV to 5.4 V for the speaker level inputs
- Turn-On Mode: three position switch:
- REM: amp turns on when +12
volts DC is applied to the remote terminal
- DC: the amp turns on when
a DC offset voltage is detected on the speaker
- Signal: the amp turns on
when an audio signal is detected on the speaker
level inputs, turns off after 30 seconds without
an input signal
- Crossover: rotary control; the crossover point is
continuously variable from 50 Hz to 200 Hz; the slope is 12 dB/octave
and the low-pass crossover is always engaged
- Polarity: two position switch; allows you to reverse
the phase of the subwoofer (0°, 180°)
Protection Circuit: The amp is equipped with thermal protection
circuit; it will shut down if it overheats.
- Width: 21" (21-1/4"
- Height: 13-1/2"
- Depth: 6-5/8" (7-3/8"
