conditions such as voltage spikes, short circuit and over  
thermal limits. When any of these conditions exist, the  
protection circuit will shut down the amplifier and light up the  
protection indicator to identify the problem. Once the problem  
is resolved, the amplifier will return to normal operation  
automatically.

MULTI-FUNCTION PROTECTION INDICATOR  
When the red protect indicator lights up it signifies a high  
operating temperature is detected and the amplifier is  
temporarily shut down to allow for a cooling period. As soon  
as the temperature returns to a safe level, the amplifier will  
restart and resume normal operation. This indicator also lights  
up when the amplifier detects either an over-current situation,  
shorted speaker outputs or a DC offset at the outputs.  
Turn off the amplifier; double-check all inputs and speaker  
connections to make sure there is no short or inappropriate  
input. If all connections are in order, turn on the amplifier to  
resume operation.

MONOBLOCK OWNER’S MANUAL  
INSTALLATION  
INPUT CONNECTIONS  
Connect RCA input jacks of the Amplifier to the output of the Source Unit (i.e.  
Radio, Cassette player or CD player).  
Note: Verify that your vehicle does not have a positive ground electrical system,  
this is very rare. A positive ground system is the reverse of most standard  
vehicles in that the + battery terminal is connected to the vehicle chassis and is  
typically found in some older European vehicles. If you have any questions do  
not proceed until you have verified this. If it is a positive ground electrical system  
please contact your dealer for assistance.  
SPEAKER CONNECTIONS  
When connecting the Amplifier to the Speaker, use heavy gauge speaker cable  
for these connections (14AWG recommended minimum).  
Caution: Please follow all the installation recommendations and instructions  
in this manual. Installation in any manner not outlined in the manual will  
void your warranty and may possibly cause damage to the vehicle and/or  
the amplifier.  
We recommend that the minimum total impedance of the speaker load is no  
less than 2 ohm. The amplifier has 2 each (+) terminals and 2 each (-) terminals.  
These terminals are duplicates, meaning you can use any combination of + and  
– connections for a single speaker (Model 300.1 only). Connect the positive  
(+) speaker output of the amplifier to the positive (+) terminal of the speaker.  
Connect the negative (-) speaker output of the amplifier to the negative (-)  
terminal of the speaker.  
Warning: The battery ground should remain DISCONNECTED at all stages  
of installation.  
LOCATION/MOUNTING  
Figure 4: Single Woofer Connection  
When selecting a location to mount your amplifier, please keep in mind that  
electronics are sensitive to vibration, moisture, and heat. Make sure the amplifier  
is mounted in an area with ample ventilation and is not exposed to moisture or  
external heat. For proper cooling, it is recommended to mount the amplifier  
horizontal or vertical but not upside-down. Automobiles have a certain level  
of normal vibration and we have designed the product with this in mind, but  
excessive vibration may cause damage over time. Using the amplifier for a  
template, mark the mounting holes in your selected area while following the  
preceding guidelines. Verify that you are not going to damage sensitive vehicle  
systems by drilling where you have selected (look for gas tank, wires, etc…).  
Remove the amplifier and pre-drill the locations for size screws/bolts that you  
have selected that fit the amplifier and your installation purposes, permanently  
mount the amplifier to selected location.  
CAUTION: ANY DEVIATION FROM THE ABOVE SPEAKER CONNECTION  
MAY CAUSE SERIOUS DAMAGE TO THE AMPLIFIER AND/OR SPEAKERS.  
PLEASE DOUBLE CHECK THE CONNECTION BEFORE TURNING THE  
SYSTEM ON.  
Figure 3. Typical System connection  
Note: It is best to mount the amplifier to some form of insulating surface, such  
as MDF, so that the chassis of the amplifier does not come in contact with the  
vehicle chassis (if a single screw makes contact with both the amplifier and  
vehicle chassis, it is the same as no insulator). This will lessen the possibility of  
any ground related noises and will shield minor amounts of radiated noises.

CONNECTING AMPLIFIER POWER WIRE TO THE BATTERY (B+)  
ADJUSTMENTS  
Power cables are as important as battery capacity. Use no less than an 8AWG  
(8 gauge) power cable, while 4 gauge would be optimum for most applications.  
YOU CAN NEVER HAVE TOO BIG OF A POWER/GROUND WIRE! Run the  
power cable through the interior of the vehicle (Avoid moving parts: seat rails,  
steering column, etc…) connecting one end to the amplifiers (+) terminal and  
connecting the other end to a proper sized fuse link within 18 inches of the  
positive post on the battery. If possible do not run the power cable together  
with the audio cables as it could possibly cause radiated noise in your audio  
system. It is recommended to run audio cables on one side of your car and  
power cables on the other.  
CROSSOVER FREQUENCY SELECTION  
Fully variable crossover from 25 to 250Hz. Adjust this setting according to your  
speakers specification or to your particular preference.  
Figure 6: Crossover and Frequency Selection  
INPUT SENSITIVITY ADJUSTMENT  
The Input Sensitivity Control is located on the Input Panel. The objective of  
the input sensitivity adjustment is to match the output of the source unit with  
the input of the amplifier (it is not a volume control). The output voltage of  
individual source units can vary. For example, some source units have an  
output of 200 mV others have 4 Volts or more. Adjusting this control requires  
some experimenting. Basically you want all the gain at the beginning of the  
system, NOT at the end (amplifier). Turn your source unit volume UP and keep  
your amplifier gains at the minimum possible settings. This will give you the  
best sound and signal-to-noise ratio.

Figure 7: Input Sensitivity Control  
NOTE: Turning the input gain up does not indicate more power, but increases  
the possibility of noise. The input gain control is not a volume control. The  
function of the gain is to match the voltage that the amplifier is looking for, to  
the voltage that the source unit is supplying  
1. Turn the Input Sensitivity Control all the way down (counter clockwise).  
2. Set the volume control of the source unit to approximately 3/4 of its  
maximum output.  
3. Turn the balance control of the source unit to its center position.  
4. Set the tone (bass/treble) controls to flat (zero).  
5. Play a song (original recording) with wide dynamic range  
6. To locate the optimum input sensitivity setting, turn the Input Sensitivity  
Control clockwise until audio distortion starts to develop. Turn the sensitivity  
control counter clockwise slightly until you no longer hear distortion.  
7. If you constantly switch between sources (CD/tape and radio), you will need  
further adjustment since radio output level differs from that of CD or tape. In  
this case, you need to locate a balanced sensitivity setting which is best for  
both the output level of radio and that of CD or tape.  
Note: The proper size primary fuse/circuit breaker (located within 18 inches of  
the battery) may vary depending on your system design but should not exceed  
50% of the main batteries’ amp hour rating. Using a larger value circuit breaker  
or fuse value means that you have NO protection. DO NOT over fuse! Fuses on  
the amplifier and at the battery DO NOT protect the amplifier, they protect the  
car.  
CONNECTING AMPLIFIER GROUND WIRE (B-)  
It is recommended to run a ground wire directly to the battery as you  
would do with the positive cable, to avoid any voltage losses and possible  
ground related noises. You can use the vehicle chassis, and if you chose to  
do this find a solid ground point (Frame, Strut Tower, Reinforced area near seat/  
seatbelt) and remove the paint to reveal bare metal. Attach the ground wire to  
the chosen ground source and connect the other end of the ground wire to the  
GND terminal of the amplifier.  
Note: The ground wire should be the same gauge cable as the power cable  
running from the positive post of the battery to the amplifier.  
TERMINALS AND CONNECTORS  
Proper size terminals and/or connectors are required to ensure a safe and  
secure electrical connection and conduction.  
CONNECT THE AMPLIFIER REMOTE LEAD (R)  
Figure 5: Crossover Frequency Selection  
Connect the remote “R” terminal of the amplifier to the remote output lead of  
the source unit so that the amplifier will turn on and off with the source unit. If  
the source unit does not provide a remote output, connect to the source units’  
switched 12+ volt source.  
RECONNECT THE BATTERY GROUND TO THE VEHICLE CHASSIS  
Double check all the previous installation steps, in particular, the wiring and  
component connection. If everything is in order, complete the installation by  
reconnecting the battery ground to the vehicle chassis.  
Both the high-pass and the low-  
pass section offer a fully variable  
crossover from 40 to 400Hz. Adjust  
this setting according to your  
speaker component specifications or  
to your particular preference.  
Figure 6: Input Sensitivity Control  
The Input Sensitivity Control is located on the Input Panel.  
The objective of the input sensitivity adjustment is to  
match the output of the source unit with the input of the  
amplifier (it is not a volume control). The output voltage of  
individual source units can vary.  
 
RSd AMPLIFIERS  
2 CHANNEL OWNER’S MANUAL  
TROUBLE-SHOOTING  
Very low output: Check your source unit’s fader control. Check the amplifier’s  
Input Sensitivity Level.  
SYMPTOM: POSSIBLE CAUSE  
Frequent automatic amplifier shut down: This indicates that the amplifier is  
operating at a continually undesirable high internal temperature. High operating  
temperature can be caused by inadequate ventilation: Refer to the sub-section  
titled LOCATION for better amplifier location. High operating temperature can  
also be caused by an excessively low impedance load. For instance below  
2 ohms stereo or 4 ohms bridged. Check for bad speakers or bad passive  
crossover components. If all else fails, try rewiring the entire system. High  
operating temperature can be caused by an incorrect input sensitivity level,  
refer to sub-section titled INPUT SENSITIVITY ADJUSTMENT.  
No power: Check voltage at amplifier with a DMM (volt meter), B+ and REM  
(with source unit on) the voltage should register between 12.2V-14.6V when  
using the attached ground lead of the amplifier. Check fuse at amplifier and at  
the battery. Use a meter to verify connection from one end of the fuse to the  
other, breaks may not always be visible. If fuse is blown, check the power wire  
and also the amplifier for a short. If the short is in the power wire, repair it. If  
the short is in the amplifier itself, see your Phoenix Gold dealer. If no short is  
present replace the fuse.  
Power without sound: Turn the amplifier off and check all input and output  
signal cables and power connections. Check the speakers for shorts with  
a DMM (volt meter) or by connecting them to another audio source. After  
making sure everything is normal, turn the amplifier on again.  
“Motor Boating” - the power indicator going off repeatedly when the  
audio system is on: Check the amplifier’s connection to the battery. Check  
battery voltage. If low, recharge or replace battery. Check all ground  
connections.  
Power without sound and status LED is lit red: The continuous red light of  
the power indicator signals a high internal operating temperature, which results  
in the amplifier switching off temporarily. When the amplifier cools down to a  
safe level, the amp will automatically restart. The continuous red light of the  
power indicator can also indicate a shorted speaker lead or battery voltage  
that is either too high or too low for proper operation.  
Whining noise when engine is running: Reroute power cable from battery to  
source unit directly (include fuse), bypassing the battery terminal in the fuse  
box. Check power connections to be sure they are clean. Check the battery  
ground making sure the battery terminals and chassis ground are clean. Run  
a ground wire from the source unit to the ground point of the amplifier and  
remove old source ground.  
No sound from one side: Check balance control. Check speaker connections.  
Check signal input connection.  
CAUTION: Do not disconnect the Power Amplifier’s ground when the  
system is on. This could damage the amplifier.
