9. Connect the speakers. Strip the speaker wires 1/2" and insert 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.
10. 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.
NOTE
: Follow the diagrams for proper signal polarity.
CAUTION
