Power Connections
• Power connections accept up to XTR500.4, XTR750.4, XTR1000.4
4 AWG wire and XTR1700.4, XTR2500.4 0 AWG.
• power and ground wire recommended for optimal perfor mance.
• Connect 12V+ to the battery through fuse holder. This connection
provides +12V main power to the amplifier.
• Power wire must be fused no more than 12” from battery.
• Ground amplifier to a good chassis ground as close as possible to
the amplifier.
• Recommended fuses are 80A for the XTR500.4, 90A for the
XTR750.4, 120A for the XTR1000.4 and 200A for the XTR1700.4,
300A for the XTR2500.4.
• Connect REM terminal to remote turn-on lead from source unit.
This connection provides +12V power to turn-on the amplifier.
• Add extra ground wire between the negative terminal of the
battery and the chassis.
NOTE: The addition of a ground wire from the battery to the chassis
of the vehicle improves the ability of the battery to supply power to
the amplifier. This is recommended because the current delivery of
the factory electrical system was designed only to accommodate
electronics supplied by the auto manufacturer.
Speaker Connections
The Orion amplifier offers four positive and four negative output
terminals for ease of connecting channel 1, 2, 3, and 4 outputs to the
speakers. The amplifier is stable to 2Ω per channel. See diagrams
below for possible configurations.

Four Channel Stereo Configuration
• Channel 1/2 and channel 3/4 lowest recommended impedance is
2Ω stereo.
• Crossover mode, output, and gain configurations are indepen
dently adjustable between the front and rear channels.
• Two-channel or four-channel input can be used for this configu
ration. For source unit fading, use the four-channel input mode.
• Channels 1/2 and channels 3/4 outputs can be individually
configured for highpass, low-pass, or full range operation.
