8. Connect the speakers. Strip the speaker wires 5/8" and insert
into the appropriate terminal on the amplifier. Insert the bared
wire into the speaker terminal and tighten the set screw to
secure into place. Be sure to maintain proper speaker polarity.
DO NOT chassis ground any of the speaker leads as unstable
operation may result.
9. Perform a final check of the completed system wiring to ensure
that all connections are accurate. Check all power and ground
connections for frayed wires and loose connections which
could cause problems.
After the final inspection is complete, install the power fuse
and enjoy listening. During the initial listening period, you
may need to “fine tune” any phasing and level settings within
your particular vehicle. To aid in this procedure, play a track
with high musical content and cruise around your neighbor-
hood. After fully evaluating the transient response of your
system and making any final adjustments, all your neighbors
within a 1 mile radius will assume that you have just success-
fully completed another upgrade to your audio system for
which they will probably spill thumbtacks on your driveway.
