IMPORTANT SAFETY INSTRUCTIONS
CAUTION FISK OF ELECTRIC SHOCK, A DO NOT OPEN
- To reduce risk of electric shock, never open the unit. There are no serviceable parts.
- Do not expose this unit to any kind of moisture.
- Please ensure that the unit is situated in a properly ventilated area.
- Make sure the unit is placed on a level and stable surface.
Function
-
POWER/PROTECT STATUS LEDs The top green LED (a) indicates that the unit is receiving power. The bottom red LED (b), when illuminated, indicates that the unit has gone into protect mode.
-
PHASE SHIFT BUTTON The Phase Shift switch allows you to synchronize the phase of your subwoofer output to that of the other speakers in the vehicle. It can be set to 0 or 180 degrees. Set the amp to 0 and listen to a track with some bass. Now set the control to 180 degrees, listen to the same track, and see if the bass output improves or becomes worse. Set the button to the setting which achieves the best results.
-
AUTO POWER ON The AUTO POWER ON setting is used in conjunction with high level (speaker evel) connections. When the switch is in the ON position, the subwoofer will automatically power on when there is an input signal. Please note, this feature only works when connecting via high level inputs. It will not function when using low level (RCA) inputs. Do not use the remote turn on connection when using high level inputs.
-
LOW PASS FILTER The control marked LOW PASS FILTER will control the low-pass frequencies from 50Hz to 150Hz. It allows you to set the frequency range which the subwoofer will receive. The subwoofer will reproduce all sound below the frequency you set. If your system is unable to accurately reproduce midrange frequencies, you may want to set this control closer to 150Hz. If your system accurately reproduces midrange frequencies, set the control lower.
-
BASS BOOST The control marked BASS BOOST will allow you to increase the sound level of bass frequencies up to 18 decibels.
-
INPUT GAIN CONTROL Once your system is operational, set the input sensitivity using the control marked GAIN. Turn it counterclockwise to the MIN position. Adjust your head unit’s volume gain to the maximum it can go before signal distorts or to the loudest gain, which is usually about 75% — 85% on most head units (you can also use an oscilloscope to see at what gain level your head unit distorts). When you begin to hear distortion, back down one notch. Now turn the GAIN control clockwise until you hear distortion, then turn it counterclockwise by a notch or until the distortion is gone. The RW-CA unit’s input sensitivity is now set. Please note that the GAIN control should not be mistaken for a volume control. It is intended to match the output level of your source unit to the input level of the RW-CA unit. Do not adjust the GAIN to maximum unless your input level requires it.
-
SUB LEVEL REMOTE CONTROL The dash-mounted bass remote allows you to control the amplifier’s bass level from the comfort of the driver’s seat. It features a power LED which indicates the unit is receiving power and operating nominally.
-
LOW LEVEL RCA INPUTS If your head unit has RCA outputs, connect these to the RW-CA unit’s Left and Right RCA input jacks. For best audio performance be sure to use high-quality RCA cables. Please note, when using these inputs, the AUTO POWER ON button should be set to the OFF position.
FUNCTIONS (continued) -
HIGH LEVEL (SPEAKER LEVEL) INPUTS Many factory radios do not have preamp outputs, so we’ve equipped the RW-CA units with High Level inputs. These inputs, also referred to as Speaker Level inputs, allow you to connect to the factory speaker wires (see page 3). They are called High Level inputs because they convert the high voltage running through factory speaker wires to one the RW-CA unit can handle.
-
FUSE The RW8CA uses a 20 amp fuse and the RW1OCA uses a 25 amp fuse. Never replace the supplied fuse with one of larger value. Use of a higher amperage fuse may cause damage.
-
POWER/GROUND TERMINALS and REMOTE TURN-ON CONNECTION See page 4 for instructions on how to property connect power, ground, and remote connections. LOW LEVEL INPUT
The low level (RCA) inputs are the prefered connection method. Most trunk or hatchback instal-lations will require a 15 —20 foot RCA cable, while pickup trucks and under-seat installations will require a 6 —12 foot cable. For best audio performance be sure to use high-quality RCA cables. Be sure to run the RCA cables on the side of the vehicle opposite to the side used to carry the power and ground leads of the amplifier.
WARNING: Do not use high level and low level inputs at the same time. Make sure that the AUTO TURN ON button is set to the OFF position when using low level inputs.
HIGH LEVEL INPUT
The high level input should only be used when your head unit lacks RCA
outputs. Connect the harness to the high level input port, then connect the
wires from the harness to the correspond-ing speaker wires from the head unit.
Be sure to observe proper polarity in order to avoid audio phase problems.
WARNING: Do not use high level and low level inputs at the same time.
Make sure to set the AUTO TURN ON button to the ON position. Do not connect
the remote turn on terminal when using high level inputs.
WIRING GROUND
Attach a 10-gauge or heavier wire to the terminal marked GROUND. The
connection should be as close to the RW-CA unit as possible (40 inches or
less). Connect the wire to any part of the vehicles’s metal chassis. Make sure
that there is no paint or other insulator blocking a good ground connection.
REMOTE
Connect the remote terminal to the head unit’s remote output using an 16-gauge
or heavier wire. This connection is responsible for turning the amplifier on
and off with the rest of the system. If there is no dedicated remote output,
make this connection to the power antenna lead. Should your head unit not have
any turn-on leads, you can wire the remote terminal to an accessory lead,
which will turn the RW-CA unit on with your vehicles’s ignition.
WARNING: Do not use the remote connection when using high level inputs.
Make sure that the AUTO TURN ON button is set to the OFF position.
POWER Using a 10-gauge (RW8CA) or an 8-gauge (RW1OCA) wire, connect an
in-line fuse holder to the vehicle battery’s POSITIVE (+) terminal. This in-
line fuse offers protection against damage to the battery and electrical
systems that may be caused by short circuits. Ensure the fuse holder is within
18 inches of the battery. Connect the fuse holder to the RW-CA unit’s +12V
terminal.
Remote control connection
Install the remote control securely under the dash or in a similar location where it will not distract the driver.

Troubleshooting
| PROBLEM | SOLUTION |
|---|---|
| No power | 1. Check your ground and power connections.2. Make sure the power |
terminal is receiving at least 12V.3. If Using RCA inputs, make sure the
Remote turn on is receiving at least SVDC.4. Check the fuse and replace if
necessary.5. Make sure the Protect LED is not illuminated. If it is, turn
the amplifier off and then back on.
Protection LED illuminates when the unit is powered on| 1. Check for
short-circuits on speaker leads.2. Turn down the head unit’s volume to
prevent overdriving.3. Remove the speaker leads and reset the amplifier (turn
off and then on). If the Protect LED still illuminates, the amp is faulty and
needs servicing.
No output| 1. Check the fuse and replace if necessary.2. Make sure the unit
is properly grounded.3. Make sure the Remote turn on is receiving at least
SVDC.4. Make sure the RCA cables are properly connected.5. Check your high
level connections.6. If your head unit has a separate subwoofer output,
check the settings to make sure it is enabled.
Low output| 1. Reset the gain control.2. Check the crossover control
settings.3. Power and ground cables that are too thin a gauge size for the
terminals may cause low sound. Determine the proper cable gauge necessary and
replace existing cables.
High hiss sound| 1. Check to see how your wires are run. If your RCA cables
and speaker wire are run alongside your power cables, they will pick up
feedback. If this is the case, you will need to run the RCA cable on the other
side separate from your power cable.2. Noise can be picked up due to bad RCA
cables. We recommend doing a test with different RCA cables. Replace the RCA
cables if needed.
Squealing noise| Check for improperly grounded RCA interconnects.
Distorted sound| 1. Make sure 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.2. Make sure all crossover frequencies are properly set.3. Check
for short circuits on the speaker leads.
Amplifier gets very hot| 1. Make sure the wiring is correct and you are using
the proper wires for your system.2. A poor ground cable connection can cause
your amp to get very hot. Check your ground connection and make sure that the
cable is securely tightened.3. Check the location where your amp is mounted.
Make sure it is in a spot where it will receive proper ventilation.
Engine noise (static type)| This is usually caused by poor quality RCA cables,
which can pick up radiated noise. Use high quality cables and route them away
from power cables.
Engine noise(alternator whine)| 1. Make sure the RCA grounds are not shorted
to the vehicle’s chassis.2. Make sure the head unit is properly grounded.
