Installation Warnings and Tips
•Disconnect the negative
•At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.
•Choose a safe mounting location away from moisture.
•Make sure there is sufficient air circulation at the mounting location for the amplifier to cool itself.
•Mount the amplifier, using the supplied hardware.

Speaker Output Connectors
•Connect the speakers to these terminals, observing proper polarity. Either + or – terminal may be used. Minimum total impedance is
2 ohms.
Fuse Holder
•Replace fuse only with the same type and rat- ing.
•Mount the included fuse holder within 18" of the vehicle's battery. Connect one terminal of the holder to the battery's positive (+) terminal.
Connect the other terminal of the fuse holder to the amplifier as in , below. 0 AWG wire is recommended. Make sure the wire is not damaged or pinched during installation. Install protective grommets when routing wires through the firewall or other sheet metal.
Power Input Connectors
•+12V: Connect to the unused terminal of the included fuseholder.
•GND: Connect to the vehicle’s chassis. Refer to the picture below.

Note: Remove any paint Star Washer below ring connector.
•REM: Connect to the “Remote Out” lead from the source unit or to a source of switched 12V+ (ACC).
Aux Output Connectors (RCA)
•Nonfiltered
Input Connectors (RCA)
•Connect to the RCA outputs from the source unit or signal processor.
•Used to match the input level of the amplifier to the output level of the source unit.
•See for the adjustment procedure.
•12dB/octave
•See for the adjustment procedure.
DBO (Dynamic Bass Optimization) Variable Subsonic
•For woofers in tuned (vented) enclosures, set the Frequency control to a value 10Hz below the enclosure’s resonance (tuned) frequency.
•For woofers in sealed boxes, set the control to any value you prefer, between 30Hz and 50Hz.
•Set the Boost control according to your preference, being careful not to apply enough boost to damage your woofer(s).
A DBO
See above for appropriate settings. B DBO Boost control provides up to
12dB of boost, slightly above the high- pass filter’s frequency. See above for appropriate settings.
Remote Level Control (RLC) Connector
•Connect the Remote Level Control (RLC) here, using the supplied
Power On LED
•Illuminated when the amplifier is on.
Protect LED
•Illuminated under any of the following fault conditions: battery over/under voltage, short circuit in speaker wires, amplifier is too hot, amplifier’s output circuit has failed (DC voltage is present in the amplifier’s output).
Setting Input Level
ATurn Input Level control counterclockwise to 6V (minimum).
BWith a dynamic music track playing, turn the head unit’s volume control to the 3/4 position.
CTurn Input Level control clockwise until the bass output is proportionate to the output of the
D Input level is now adjusted correctly.
Setting the Crossover
A Crossover setting for subwoofers.
Note: Acceptable frequency ranges are indicated in gray.
Remote Level Control
The Remote Level Control, if installed, will allow you to adjust the level of bass while seated in the listening position.
