Power Connections
Power connections accept up to 4 AWG wire . •
4 AWG power and ground wire recommended for optimal per- •
formance .
Connect 12V+ to the battery through a fuse holder . this connec-
•
tion 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 50A for the XtR2504, and 100A for the
•
XtR5004 .
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 electron-
ics supplied by the auto manufacturer .
Speaker Connections XTR2504 and XTR5004
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 .
