XPR520 INSTALLATION / OWNER'S MANUAL Mobile Power Amplifier
Preparation Please read entire manual before installation. Due to the technical nature of amplifiers, it is highly recommended that your DUAL amplifier is installed by a professional installer or an authorized dealer. Before You Start • Disconnect negative battery terminal. (consult a qualified technician for instructions) • Avoid installing the amplifier where it would be subject to high temperatures, such as from direct sunlight, or where it would be subject to dust, dirt or excessive vibration.
Connection Descriptions Note: Be sure to follow specific instructions included with your amplifier installation kit (not included with this amplifier). The information below should be used a general guideline only. Power Wire (BAT+) • Disconnect negative battery terminal before proceeding. Consult a qualified technician for instructions if you are unsure. • Plan wire routing before cutting any wires to length. Begin by routing the power +12V wire from the battery to the amplifier location.

Typical Wire Routing Main Power Connections Connect +12V, GND and REM wires accordingly. A suitable fuse MUST be installed on the +12V lead within 18" of the battery for protection of the vehicle’s electrical system. Fuse Rating Power/Ground Wire Size When replacing fuses, make sure new fuse is the correct type and amperage. Using an incorrect fuse could damage the amplifier. For optimum performance, use only the wire size listed below or larger. Make sure to use the same size power and ground wire.
Amplifier Connections Speaker Connections 2 Speakers (stereo) Subwoofer (mono) Typical Stereo Wiring Typical Bridged Wiring Connect speaker wires observing polarity. The minimum impedance load for the XPR520 is 2 ohms stereo and 4 ohms bridged. Use of loads lower than these is not recommended and may cause amplifier damage. The XPR520 can be wired for stereo, bridged or stereo/bridged simultaneous operation.
Configuration/Setup Input level Control The input level control (gain) is used to obtain the best possible match between the head unit audio output and the amplifier input. • Begin by turning the input level control fully counterclockwise. • Next, turn up the head unit volume control around 3/4 of the way up. • Adjust the input level control clockwise until audible distortion is heard, then slightly counterclockwise to provide the best match. • Repeat for all input level controls.
