at all audio frequencies with minimum distortion. You can connect your

autosound system's low-level or speaker-level outputs to this amplifier.

Its features include:

14K Gold-Plated Noise-Isolated Low-Level Input Jacks - let you connect low-

level (preamplifier) signal inputs to match your

autosound system's output for the best high-fidelity

performance.

14K Gold-Plated Speaker Terminals - designed for low impedance, high

conductivity, and minimum corrosion, to provide

the highest signal transfer and lowest sound

distortion.

Input Level Control - lets you adjust the level of the audio signals that

enter the amplifier.

the amount of power supplied to the speakers from the amplifier. Use the supplied wire harness and the supplied twist-on terminal connectors to make the appropriate connections. CONNECTING SPEAKERS You can connect two speakers or a subwoofer to the amplifier and your autosound system. If you are connecting two speakers, follow steps 1-3 under "Preparing the Speaker Wires" then see "Connecting a Subwoofer" to connect the subwoofer to the amplifier.

connections (ground, primary power, remote power, your autosound system's input, and speakers). Note: If you have not already done so, be sure to mark each wire with the name of the terminal you will reconnect it to. 3. Using the mounting holes on the amplifier as a guide, mark the positions for the mounting holes. 4. Drill 9/64-inch (3.57 mm) holes at the marked locations, being careful not to damage anything behind the mounting surface. 5.

ADJUSTING FREQUENCY CROSSOVER If you installed a subwoofer using the steps in "Connections," Faxback Doc. # 44363, set X-OVER FREQ ON/OFF to ON, then adjust X-OVER FREQ for your particular vehicle's acoustics. The amplifier passes through all frequencies at or below that setting (45-400 Hz). Note: X-0VER FREQ selects the limit at which the amplifier will pass frequencies (from 45-400 Hz). You should not use it to adjust the sound you hear through your main speakers.

XL-110 Stereo Amplifier (120-2014) Troubleshooting Faxback Doc. # 44365 We do not expect you to have any problems with your Optimus XL-110 High Power Stereo Amplifier, but if you have a problem, this chart might help. If it does not, take the amplifier to your local RadioShack store for assistance. SYMPTOM POSSIBLE CAUSE SUGGESTION No power - the amplifier's POWER indicator does not light after the vehicle's autosound system is turned on. Power problem.
PAGE 14
The amplifier detected an input overload. Reduce the autosound system's volume. Distorted sound. The amplifier's PROTECTION indicator lights. Power problem. Check the amplifier's and autosound system's fuses and replace them if necessary. The amplifier might be receiving too much input power from your autosound system. Reduce your autosound system's output power (if possible), or reduce the autosound system's volume. An output channel might have shorted.

Caution: Do not use a fuse with ratings other than those specified here. 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. 3. If the fuse is blown, replace it. Use only an SFE-type fuse with the proper rating (such as Cat. No. 270-1074). The fuse must be 20 amps. 4.
