Overview: The ACP108LG-W3v3 MicroSub+ is a compact powered subwoofer, useful in vehicles with limited space. The ported enclosure is loaded with one 8W3v3-0.40 8" low impedance subwoofer (0.4Ω) and a 250 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 grille. The port and amplifier panel are both on the same side of the enclosure.
Flared Port: The enclosure has a side-firing flared slot-port. The flared slot-port design minimizes turbulence and improves fidelity. The port is approximately 1-3/8" x 4" at the opening.
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 included.
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 vehicle.
- 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 level inputs
- 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: 18-1/2" (18-3/4" including wiring)
- Height: 11-1/8"
- Depth: 5-1/8" (6-5/8" including grille)
