At this point, the power, ground and remote wires should be run to the general
location of where the amplifier is to be mounted. If the wires are to be hidden under
the carpet, you now need to cut a slit for them to come through. To do this, place
the amplifier in the location it is to be mounted to verify where the cuts need to be
made. Make sure that there will be not be a conflict with the mounting of the
amplifier and the wires. Pull the wires through the slit to the terminals leaving
approximately 6" (150mm) of slack and cut the wires to an equal length. Strip off
approximately
½
" (12mm) of insulation from each wire. Insert the wires directly into
the terminal and tighten the set screw using a 3mm allen key. Make sure you have
the polarity correct on both the power wires and the speaker wires. Check your
connections by giving the wires a slight tug.
Connecting the Wires
Getting a clear signal from the head unit to the amplifier is very important. To
achieve this, the proper signal cables must be used. Estimate the length of the
cables necessary. Take note that the cables will probably not be the exact length
necessary for your vehicle. If you are between sizes, purchase the longer cable.
You can always hide the extra wire.
Be aware of the differences in cable. Better RCA's usually have multiple layers of
shielding and/or twisted pair wiring for better noise rejection. Consult your local
dealer for their recommendations.
Signal Inputs
LINE LEVEL INPUTS
Car environments are notorious for poorly insulated wires. This means that hiss,
engine noise, and fan noise can easily be picked up through RCA cables if ran
incorrectly. To avoid picking up noise, run the RCA's away from large wire looms
and electric fans if possible. Always make sure to position your patch cables away
from the power wire, preferably on the opposite side of the vehicle. As with the
power wire, use caution around sharp corners of body parts that may easily cut
through the cables.
Located on the opposite side of the power terminals are two sets of line level (RCA)
receptacles. Marked "LOW IN", these receptacles accept signal from the outputs of
the source unit via RCA patch cables. When connecting the signal cables, be sure
the balance (left and right) stays consistent between the amplifier and head unit.
The cables should be marked for easy installation: red is right and black or white is
left.
Once you have finished connecting the signal cables to the source unit, slide the
head unit back into the dash location. Make sure that the head unit is in securely.
