Installation
2. Prepare the RED wire (power cable) for attachment to the
amplifier by stripping 1/2” of insulation from the end of the
wire. Insert the bared wire into the B+ terminal of the power
connector and tighten the set screw to secure the cable in
place.
NOTE: The B+ cable MUST be fused 18” or less from the
vehicle’s battery. Install the fuseholder under the hood and
ensure connections are water tight.
3. Trim the RED wire (power cable) within 18” of the battery
and splice in a inline fuse holder (not supplied). See
Specifications for the rating of the fuse to be used. DO NOT
install the fuse at this time.
4. Strip 1/2” from the battery end of the power cable and crimp
an appropriate size ring terminal to the cable. Use the ring
terminal to connect to the battery positive terminal.
5. Prepare the BLACK wire (Ground cable) for attachment to
the amplifier by stripping 1/2” of insulation from the end of
the wire. Insert the bare wire into the GROUND terminal of
the power connector and tighten the set screw to secure
the cable in place. Prepare the chassis ground by scraping
any paint from the metal surface and thoroughly clean the
area of all dirt and grease. Strip the other end of the wire
and attach a ring connector. Fasten the cable to the chassis
using a non-anodized screw and a star washer.
NOTE: Keep the length of the BLACK wire (Ground) as short
as possible. Always less than 30”.
6. Prepare the Remote turn-on wire for attachment to the
amplifier by stripping 1/2” of insulation from the end of the
wire. Insert the bared wire into the REMOTE terminal of the
power connector and tighten the set screw to secure the
wire in place. Connect the other end of the Remote wire to
a switched 12 volt positive source. The switched voltage is
usually taken from the source unit’s remote amp on lead.
If the source unit does not have this output available, the
recommended solution is to wire a mechanical switch in line
with a 12 volt source to activate the amplifier.
NOTE: In the event that a sw12V is not available,
either DC offset or Audio sense can be selected for amplifier
turn-on.
7. Connect the power connector to the mating connector at
the amplifier.
8. Connect from source signal by plugging the RCA cables
into the RCA/Speaker Harness input jacks, then insert the
four pin Molex connector into the mating four pin INPUT
connector at the amplifier.
NOTE: When the installation requires a High Level(Speaker)
input, the RCA/Speaker Harness will need to be cut on the
speaker wire side of the y-splitter.Then connect the white to
the left(+), white/black to the left(-), grey to the right(+), and
grey/black to the right(-) corresponding vehicle wires.
Always ensure power is off or disconnected at the amplifier
before connecting RCA cables. Failure to do so may cause
damage to the amplifier and/or connected components.
9. Perform a final check of the
completed system wiring to ensure that
all connections are accurate. Check
all power and ground connections for
frayed wires and loose connections
which could cause problems. Install
inline fuse near battery connection.
