Speaker Wiring
For your convenience, two sets of two-conductor wire are provided to use
between the speakers and the amplifier or head-unit. Other wire may be
substituted if desired as long as it is at least 18 gauge. Sometimes the
stock speaker wires in the vehicle may be used.
Two-conductor speaker wire connects the positive and negative termi-
nals of each speaker to the corresponding positive and negative termi-
nals on the amp or head-unit. One side of the wire will be marked in some
way. Use the marked conductor to connect the positive terminals and the
plain conductor to connect the negative terminals.
Routing the Wires
Include a large safety margin when estimating the length of each wire.
For Doors: Run the wires through factory harnesses or existing holes,
if possible. If drilling new holes, file the edges and install rubber grom-
mets and PVC tubing to protect the wires against abrasion.
For Rear Deck: Run wires along the door sills just inside the car, lifting
and replacing carpet as required. You may have to remove the rear seat
to pass wires back to the rear.
