PREPARATION  
SUPPLIED HARDWARE  
Your amplifier comes with the following items. Be sure you locate everything shown  
before you store or dispose of the packing materials.  
(illustration - show all amplifier parts, wires, and hardware)  
BEFORE YOU BEGIN THE INSTALLATION  
Before you install your amplifier, read all the instructions in this owner’s manual.  
And, you should be able to answer all of these questions about your vehicle’s elec-  
trical and autosound systems.  
• Does my vehicle have an autosound system, such as a car stereo or CD  
player, already installed? (You must have an existing autosound system to use  
this amplifier.)  
• How do I connect a wire to the fuse box?  
• Which of the autosound system’s wires is the power wire?  
• Which of the autosound system’s terminals are low-level outputs and which are  
high-level (speaker) outputs?  
Also, be aware that installation in your vehicle might require cutting or modifying  
your vehicle.

Choosing a Mounting  
Location  
Routing Cables and Wires  
Avoid routing the connection cables  
and any speaker wires near moving  
parts or sharp edges. You can usually  
route wires and cables along the wiring  
channel beneath the vehicle’s door fac-  
ings by carefully removing the molding  
that holds the carpet in place. After  
routing the cables and wires, replace  
the molding.  
A good location for mounting the am-  
plifier is in your vehicle’s trunk. Wher-  
ever you decide to mount it, choose a  
location that:  
• Does not interfere with the vehi-  
cle’s operation  
• Lets you drill mounting holes with-  
out damaging other vehicle com-  
ponents  
INSTALLATION ORDER  
• Allows enough space around the  
cooling fins for proper airflow and  
cooling  
For trouble-free installation, simply fol-  
low the sections in this Owner’s Manu-  
al in order. First, temporarily connect  
the amplifier to:  
• Lets you easily see the amplifier’s  
POWER and PROTECTION indi-

Your speakers  
Then test the connections. When you  
verify that everything works as expect-  
ed, disconnect the amplifier, mount it in  
your vehicle, and reconnect it.  
Preparing the Mounting Area  
Before you mount the amplifier, make  
sure you have all the materials you  
need, such as an adapter harness,  
additional wire, shielded audio cables,  
and 16- or 18-gauge marked or color-  
coded wires.  
Caution: If you do not make the con-  
nections in the order shown, damage  
to the amplifier and your autosound  
system is possible if any wire connec-  
tions are made incorrectly.  
Then confirm that the amplifier fits in  
your vehicle’s available mounting ar-  
ea. This amplifier requires a 21/16-inch  
high by 10-inch wide by 121/8-inch deep  
(5.2 ¥ 25.4 ¥ 30.8 cm) mounting area  
with adequate ventilation space.  
Note: For easier installation, mark  
each wire you plan to connect with the  
name of the terminal you will connect  
it to.

Cautions:  
BEFORE YOU MAKE THE  
CONNECTIONS  
• For added safety and to protect  
your amplifier and autosound sys-  
tem, disconnect the cable from  
your vehicle’s negative (–) battery  
terminal before you begin.  
The supplied connection cables in-  
clude all the lead wires you need to  
connect the amplifier to ground, power,  
and your existing autosound system.  
Important:  
• Do not cut these wires. If you cut  
any wire, you cannot obtain a  
refund or exchange on this prod-  
uct. However, RadioShack will  
provide warranty service if you cut  
a wire and find the product is  
defective.  
• Be sure your front speakers can  
handle as much as 20 watts per  
channel and your rear speakers  
as much as 55 watts per channel  
of power. Each speaker must  
have an impedance of at least 4  
ohms. Your local RadioShack  
store carries a full line of speak-  
ers.  
• If the connectors on your vehicle’s  
autosound system are not com-  
patible with the amplifier’s con-  
nectors, you might need an  
adapter harness to complete the  
connections. RadioShack stores  
sell adapter harnesses for most  
vehicles.  
To make it easier to gauge wire length  
and connect the amplifier, temporarily  
place the amplifier as close as possible  
to the selected mounting location.  
You might need additional wire, de-  
pending on your individual autosound  
system, to complete the connections.  
Your local RadioShack store carries a  
full line of wire and wire management  
accessories.

Note: A floating ground connection  
lets the amplifier provide more power  
to each speaker, but requires that you  
connect a separate wire to each  
speaker terminal. A common ground  
connection lets you use fewer wires to  
connect the speakers to the amplifier,  
but reduces the amount of power sup-  
plied to the speakers from the amplifier.

1. With the speakers placed in their  
approximate locations, run one  
wire from each speaker to the  
amplifier.  
CONNECTING  
SPEAKERS  
You can connect two or four speakers  
to the amplifier and your autosound  
system.  
If you are connecting a subwoofer,  
run two wires from each of the  
subwoofer’s terminals to the  
amplifier.  
Preparing the Speaker Wires  
2. Separate each wire’s two conduc-  
tors at both ends for a length of  
about 4 inches.  
Caution: You must connect a sepa-  
rate wire to each speaker terminal as  
described in the following procedures.  
Only use a common ground wire or  
chassis ground if your autosound sys-  
tem is wired for it.  
3. Strip the insulation from the ends  
1
of each conductor to expose /4  
inch of wire. Twist the ends to  
secure loose strands.  
Notes:  
Wire Strands  
• We recommend you use 16- or 18-  
gauge marked or color-coded  
wires to help you correctly connect  
the speakers to your amplifier.  
Conductors  
• Color-coded wires have a stripe  
running down one of the conduc-  
tors or different colored insulation  
for each conductor. Your local  
RadioShack store has a wide  
selection of speaker wire to  
choose from.  
• For the maximum bass response  
and the best overall performance,  
keep your speakers properly  
phased (connect + to + and – to –).

3. Adjust both LEVEL (MIN/MAX) con-  
trols to a comfortable listening  
level.  
4. Turn up the autosound system’s  
volume control until the sound  
begins to distort. Then immedi-  
ately turn the volume down to a  
point just before where the distor-  
tion began.  
Important: Your amplifier requires 25  
amps or more of power from your vehi-  
cle’s battery during operation. To pro-  
tect your battery from discharging, do  
not operate the amplifier unless your  
vehicle is running.  
Caution: Never turn up the auto-  
sound system’s volume control  
more than needed to adjust the  
audio level, or more than two-  
thirds of its maximum volume.  
Note: Your amplifier temporarily shuts  
down if it gets too hot, then restarts au-  
tomatically once it cools.  
5. Adjust both LEVEL (MIN/MAX) con-  
trols until the sound is at the maxi-  
mum level you want the amplifier  
to produce.  
ADJUSTING THE AUDIO  
LEVEL  
For the best performance, you must  
set LEVEL (MIN/MAX) on the end of the  
amplifier to adjust the level of the audio  
signals that enter the amplifier.  
6. Adjust the autosound system’s  
volume control to a comfortable  
listening level.

CARE AND MAINTENANCE  
Your Optimus XL-150 High Power 4-Channel Stereo Amplifier is an example of su-  
perior design and craftsmanship. The following suggestions will help you care for  
your amplifier so you can enjoy it for years.  
Keep the amplifier dry. If it gets wet, wipe it dry immediately. Liquids  
might contain minerals that can corrode the electronic circuits.  
Keep the amplifier away from dust and dirt, which can cause prema-  
ture wear of parts.  
Handle the amplifier gently and carefully. Dropping it can damage cir-  
cuit boards and cases and can cause the amplifier to work improper-  
ly.  
Wipe the amplifier with a damp cloth occasionally to keep it looking  
new. Do not use harsh chemicals, cleaning solvents, or strong deter-  
gents to clean the amplifier.  
Modifying or tampering with the amplifier’s internal components can cause a mal-  
function and might invalidate your amplifier’s warranty and void your FCC authoriza-  
tion to operate it. If your amplifier is not performing as it should, take it to your local  
RadioShack store for assistance.  
THE FCC WANTS YOU TO KNOW  
Your amplifier might cause TV or radio interference even when it is operating prop-  
erly. To determine whether your amplifier is causing the interference, turn off your  
amplifier. If the interference goes away, your amplifier is causing it. Try to eliminate  
the interference by:  
• Moving your amplifier away from the receiver  
• Contacting your local RadioShack store for help

2. Push together and twist the fuse  
holder’s parts on the red power  
cable until they spring apart. Then  
remove the fuse.  
REPLACING A FUSE  
If the amplifier does not operate, you  
might need to replace the red power  
cable’s 25-amp SFE-type fuse or the  
25-amp blade-type fuse on the amplifi-  
er’s back panel. Check both fuses.  
(illus - show fuse holder)  
Important: Let the amplifier cool  
down and see if it starts again before  
you assume a fuse needs to be re-  
placed.  
3. If the fuse is blown, replace it. Use  
only an SFE-type fuse with the  
proper rating (available at many  
automotive supply stores). The  
fuse must be 25 amps.  
Caution: Do not use a fuse with rat-  
ings other than those specified here.  
Doing so might damage your amplifi-  
er.  
4. Reassemble the fuse holder by  
inserting the fuse into the longer  
of the fuse holder’s ends, and  
pushing together and twisting the  
two parts until they latch.  
Replacing the SFE-Type Fuse  
1. Disconnect the cable from the  
vehicle’s negative (–) battery ter-  
minal.  
5. Reconnect the cable to the vehi-  
cle’s negative (–) battery terminal.
