Overview:
The JVC drvn CW-DRA8 is an amplified subwoofer with a built-in Class D amplifier.
It contains an 8" cone woofer, which is driven by a 150-watt RMS (250W Max) amp. The acoustic
suspension (sealed) enclosure is compact enough to fit under the seat, behind the seat, or
in small storage compartments. The CW-DRA8 comes with a wired remote control to let you control
its volume, phase, and the frequency of the low-pass filter.
Enclosure:
The CW-DRA8 features a specially designed acoustic suspension enclosure. It includes
a 7-1/2" metal mesh grille (non-removable) to protect the woofer.
Wired Control:
The active subwoofer comes with a wired remote control with a 16.25' cable. From
the control, you can set the volume, and vary the Frequency Control (of the built-in low pass filter)
from 50 Hz to 125 Hz. In addition, you can switch the phase of the woofer from 0°(normal) to
180° (reverse), if needed.
Connections:
The CW-DRA8 comes with a single harness with power/ground/turn-on wiring
and RCA input connections. The harness has 16.25' lengths of 14-gauge power wire (with an in-line
10A ATO fuse) and 18-gauge turn-on lead, plus a 5' dual 18-gauge ground wire. It also includes a
28" RCA input for connecting the subwoofer to an aftermarket stereo via RCA cables. A 14' speaker
input harness is provided for connecting the sub to a factory radio (or a radio without RCA outputs).
You can splice it to the head unit's speaker wires and plug it into the RCA input. An RJ-45 jack is
provided on the bottom of the subwoofer for plugging in the remote control cable.
Controls:
The only controls for the DRA8 are located on the wired remote. The rotary volume control
(input sensitivity) lets you match the input of the subwoofer to the output of the head unit, and to control
the volume of the sub, relative to the other speakers in the system. The rotary frequency control
adjusts the cutoff frequency of the low-pass filter between 50Hz and 125Hz. If you have large main
speakers (6x9 or 6-1/2") in the vehicle, you can set the subwoofer's low pass filter near the 50Hz to
80Hz range. If the main speakers are smaller (4" or 5-1/4"), the low pass filter should be set in the
100Hz to 125Hz range.
Installation:
The subwoofer comes with the hardware needed for installation. The enclosure installs
using two brackets (included) attached on opposite ends. The power, remote, and signal connections
are made in a recessed area on the bottom of the unit. The wires exit through a channel on the
side of the unit. The included cable clamp holds the power, remote, and signal wires in place as
they exit the channel.
