Notes
If you experience operation or performance problems with this product, compare your
installation with the electrical wiring diagram on the previous pages. If problems persist,
read the following troubleshooting tips which may help eliminate the problems.
Low Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk
or hatchback installations will require a 15-20 foot RCA cable, while pickup trucks
and under-seat installations will require a 6-12 foot RCA cable. Always use a high-
quality cable.
NOTE: Do not connect BOTH the high level and low level inputs from your
receiver to your amplifier at the same time!
Protection LED
comes on when
amplifier is
powered up. Check for short circuits on speaker leads.
Turn down the volume control on the head unit to prevent overdriving.
Remote speaker leads, and reset the amplifier. If the Protection LED still
comes on, then the amplifier is faulty and needs servicing.
High hiss in the
sound. Disconnect all RCA inputs to the power sub’s control panel. If the hiss
disappears, then plug in the component driving the amplifier and unplug
its inputs. If the hiss disappears at this point, go on until the faulty/noisy
component is found.
It is best to set the amplifier's input level control as low as possible. The
best subjective signal-to-noise ratio is achieved in this manner. Try to
set the head unit as high as possible (without distortion) and the amp
input level as low as possible.
Squealing noise
is present. Check for improperly grounded RCA interconnects.
Distorted sound. Check that the Input Level Control is set to match the signal level of the
head unit. Always try to set the Input Level as low as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets
very hot. Check that the minimum speaker impedance for the amp model is correct.
Check that there is good air circulation around the amp. In some
applications, it may be necessary to add and external cooling fan.
Engine noise
(static type) This is usually caused by poor quality RCA cables,which can pick up
radiated noise. Use only the best quality cables, and route them away
from power cables.
Engine noise
(alternator
whine) Check that the RCA grounds are not shorted to the vehicle chassis/
Check that the head unit is properly grounded.

6. Connect all line inputs and outputs (if
used) using high-quality cables. Connect
all speakers, following the diagrams in
this manual. Be sure to observe proper
polarity to avoid audio phase problems.
7. Insert fuse(s) into the battery fuse
holder(s).
8. Recheck all connections before
powering up the subwoofer.
9. Set all level controls to minimum
position, and set all crossover
controls/switches to the desired
frequency points.
10. Power up the head unit and the
subwoofer. Then set the volume control
on the head unit to about 3/4 volume,
and adjust the subwoofer's input level
controls to just below the level of
distortion.
11. Further fine tuning of the various
controls may be necessary to obtain best
results.
High Level Input Wiring
The high level input(s) should only be used when your receiver lacks RCA outputs.
If the RCA outputs are not present, connect the speaker outputs from the receiver
to the high level input connector of the amplifier. Be sure to observe polarity to
avoid audio phase problems.
NOTE: Do not connect BOTH the high level and low level inputs from your
receiver to your amplifier at the same time!
Connect the ground terminal to the closest point on the chassis of the vehicle.
Keep this ground wire to less than 39" (100 cm) in length. Use 8 gauge (or heavier)
wire.
Connect the remote terminal to the remote output of the head unit using 16 gauge
(or heavier) wire.
Connect an empty fuse holder within 18" (45 cm) of the car battery, and run 8 gauge
(or heavier) cable from this fuse to the amplifier location. Then connect the fuse
holder to the "BATT+" connection on the subwoofer rear panel.
Install the remote control securely
under the dash or in a similar
location where using it will not
distract the driver.
