Features
Your RadioShack High Power 4/3/2-Chan­nel Bridgeable Amplifier produces a total of 400 watts to give added punch and power to your vehicle’s existing auto sound system.
The amplifier produces up to 200 watts per channel (if bridged) of clean, powerful sound at all audio frequencies with minimum distor­tion. You can connect your auto sound sys­tem’s low-level or speaker-level outputs to this amplifier.
Its features include:
14K Gold-Plated Noise-Isolated Low-Lev­el Input Jacks
(preamplifier) signal inputs to match your auto sound system’s output for the best high­fidelity performance.
14K Gold-Plated Speaker Terminals
signed for low impedance, high conductivity, and minimum corrosion, to provide the high­est signal transfer and lowest sound distor­tion.
Input Level Controls
level of the audio signals that enter the am­plifier.
Automatic Power Switching
matically turn the amplifier on or off when you turn your auto sound system on or off (depending on how you hook up the amplifi­er).
Bridging Capability
amplifier’s four 100-watt channels so you can use the amplifier with only two channels that produce a total of 200 watts from each chan­nel.

THE FCC WANTS YOU TO KNOW
Your amplifier might cause TV or radio inter­ference even when it is operating properly. 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
If you cannot eliminate the interference, the FCC requires that you stop using your ampli­fier.

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.
Power Wire (Red) (1)
Ground Wire (Black) (1)
Remote Wire (Blue/White) (1)
4-Pin Connector with Wire (2)
Sheet Metal Screws (4)
BEFORE YOU BEGIN THE INSTALLATION
Before you install your amplifier, read all the instructions in this owner’s manual. You should be able to answer all of the se ques­tions about your vehicle’s electrical and auto sound systems.
• Does my vehicle have an auto sound system, such as a car stereo or CD player, already installed? (You must have an existing auto sound system to use this amplifier.)
• How do I connect a wire to the fuse box?
• Which of the auto sound system’s wires is the power wire?
• Which of the auto sound system’s termi­nals are low-level outputs and which are high-level (speaker) outputs?
Flat Washers (4)
Lock Washers (4)
Also, be aware that installation in your vehi­cle might require cutting or modifying your vehicle.
Twist-On Terminal Connectors (9)
Choosing a Mounting Location
A good location for mounting the amplifier is in your vehicle’s trunk. Wherever you decide to mount it, choose a mounting location that:
• Does not interfere with the vehicle’s operation
• Lets you drill mounting holes without damaging other vehicle component s
• Allows enough space around the cooling fins for proper airflow and cooling
• Lets you easily see the amplifier’s POWER and PROTECTION indicators

Preparing the Mounting Area
Before you mount the amplifier, make sure you have these materials.
• an adapter harness
• additional wire
• shielded audio cables
• 16- or 18-gauge marked or color-coded wires
Then confirm that the amplifier fits in your ve­hicle’s available mounting area. This amp lifi­er requires a 5 wide by 171/2-inch deep (13.9 × 34.3 × 43.1 cm) mounting area with adequate ventilation space.

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 facings by carefully removing the molding that holds the carpet in place. Af­ter routing the cables and wires, replace the molding.
INSTALLATION ORDER
For trouble-free installation, simply follow the sections in this owner’s manual in order. First make all the connections by temporarily con­necting the amplifier to:
1
Ground and power
Then test the connections. When you verify that everything works as expected, discon­nect the amplifier, mount it in your vehicle, and reconnect it.
Caution:
in the order shown, damage to the amplifier and your auto sound system is possible if any wire connections are made incorrectly.
Note:
you plan to connect with the name of the ter­minal you will connect it to.
If you do not make the connections
For easier installation, mark each wire
BEFORE YOU MAKE THE CONNECTIONS
The supplied connection cables include all the lead wires you need to connect the am­plifier to ground, power, and your existing auto sound system.
Important:
• Do not cut these wires. If you cut any wire, you cannot obtain a refund or exchange on this product. However,

• If the connectors on your vehicle’s auto sound system are not compatible with the amplifier’s connectors, you might need an adapter harness to complete the connections. RadioShack stores sell adapter harnesses for most vehicles.
You might need additional wire, depending on your individual auto sound system, to complete the connections. Your local Ra­dioShack store carries a full line of wire and wire management accessories.

using either a floating or common ground connection.
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 supplied to the speakers from the amplifier.
Use the supplied wire harnesses and the supplied twist-on terminal connectors to make the appropriate connections.

Notes:
• Use 16- or 18-gauge marked or color­coded wires to help you correctly con­nect the speakers to your amplifier.
• Color-coded wires have a stripe running down one of the conductors or different colored insulation for each conductor. Your local RadioShack store has a wid e selection of speaker wire.

CARE
To enjoy your amplifier for a long time:
• Keep the amplifier dry. If it gets wet, wipe it dry immediately.
• Use and store the amplifier only in nor­mal temperature environments.
• Handle the amplifier gently and care­fully. Do not drop it.
• Keep the amplifier away from dust and dirt.
• Wipe the amplifier with a damp cloth occasionally to keep it looking new.
Modifying or tampering with the amplifier’s internal components can cause a malfunc­tion and might invalidate its warranty and void your FCC authorization to operate it. If your amplifier is not performing as it should, take it to your local RadioShack store for as­sistance.
REPLACING A FUSE
If the amplifier does not operate, you might need to replace the red power cable’s 60­amp SFE-type fuse or one or both of the 30­amp blade-type fuses on the amplifier’s back panel. Check all fuses.
Caution:
Do not use a fuse with ratings other than those specified. Doing so might damage your amplifier.
Replacing the SFE-Type Fuse
1. Disconnect the cable from the vehicle’s negative (–) battery terminal.
2. Push together and twist the fuse holder’s parts on the red power cable until they spring apart. Then remove the fuse.
Fuse
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 60 amps.
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 together.
5. Reconnect the cable to the vehicle’s negative (–) battery terminal.
Important:
Let the amplifier cool down and see if it starts again before you assume a fuse needs to be replaced.
Troubleshooting
Replacing the Blade-Type Fuses

5. Reconnect the cable to the vehicle’s negative (–) battery terminal.
