INTELLi Bass Control
INTELLi Bass maximizes the performance of a subwoofer and allows for continuous adjust-
ment of low frequency boost. INTELLi Bass can be adjusted from 0dB to 16dB of boost cen-
tered at 45Hz. Initially the Q is very low (wide). As INTELLi Bass is added, the Q rises (nar-
rows). This allows the Orion 8004 to overcome acoustic deficiencies in your vehicle. The type
of enclosure used, the sub-woofer's excursion capability, personal preference, and attitude
determine acceptable boost levels.
WARNING! Exercise caution when setting INTELLi Bass. Maximum boost can potentially
cause woofer damage due to overexcursion.
AMPLIFIER WIRING
Power Connections
● Fuse Size: 100 AMP MAXI
● Minimum 8 gauge power and ground cable is recommended for acceptable per-
formance.
● Fuse power wire prior to wire passing through panels or near sharp edges and less
than 18" from battery.
● Ground amplifier to a good chassis ground as close as possible to the amplifier.
● Add extra ground wire (minimum 8 gauge) 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 helps
especially in newer vehicles, where the current delivery of the factory electrical
system was designed only to accommodate electronics supplied by the auto man-
ufacturer.
Speaker Connections
Four Channel Stereo Configuration
● Front and rear channel lowest recommended impedance is 2W stereo
● Crossover mode, output, and gain configurations are independently adjustable
between the front and rear channels.
● Two-channel or four-channel input can be used for this configuration. For source
unit fading, use the four-channel input mode.
● Front and rear outputs can be configured for high-pass, low-pass, or full range
operation.
● Only the rear speaker is controlled when using the RGC-1.
