XPA SERIES INSTALLATION 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. 6 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.
XPA SERIES INSTALLATION Amplifier Connections Speaker Connections Connect speaker wires observing polarity. The minimum impedance load for the XPA2500 and XPA4640 is 2 ohms stereo and 4 ohms bridged. Use of loads lower than these is not recommended and may cause amplifier damage. The XPA2500 and XPA4640 can be wired for stereo, bridged or stereo/bridged simultaneous operation.
XPA SERIES 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.
