NOTE: Be sure to follow specific instructions included with your amplifier installation
kit (not included with this amplifier). The information below should be used a general
guideline only.
Power Wire (+12V)
• Disconnect negative battery terminal before proceeding. Consult a qualified
technician for instructions if you are unsure.
• Plan wire routing before cutting any wires to length. Begin by routing the power
+12V wire from the battery to the amplifier location. Use a grommet when running
wires through the firewall or metal openings. Avoid running the power wire near
existing vehicle wiring to prevent induced noise from entering the audio system.
• Use extreme caution when drilling holes to avoid damaging fuel lines or existing
vehicle wiring.
• The +12V wire MUST be fused within 18" of the battery for protection of the vehicle’s
electrical system.
Ground Wire (GND)
• The amplifier ground wire should be as short as possible. Choose a clean unpainted
section of metal or the vehicle chassis when attaching the ground connection.
Be sure to clean the area of any dirt or grease.
Remote Turn-on Wire (REM)
• The remote turn-on wire connects to the head unit's amplifier turn-on lead or
power antenna output.
Speaker Wires
• Choose adequate gauge speaker wire depending on your exact amplifier/speaker
combination. Be sure to observe polarity when connecting.
• Do not ground any speaker wires or connect any speaker wires together.
Illuminite Circuit (12VDC Output - for DUAL illuminite speakers only)
• Use 18-gauge or larger wire for making the connections to the illuminite terminals
of DUAL illuminite speakers ONLY. Be sure to observe polarity when connecting.
• Do not ground any illuminite output wires or connect any illuminite wires together.
Input Signal
• The amplifier's input signal connects to the head unit's low level (RCA) or high level
(speaker wire) outputs.
• Low level input signal deliver the best performance. If unavailable, use the high
level inputs - when interfacing with factory head unit for instance.
CAUTION
• Do not use both low and high level inputs at the same time - connect only one or
the other.
