If amplifier gain is raised improperly, this will
simply increase distortion, with little increase
in power.

• The maximum length of the wire be-
tween the fuse and the positive 8, term-
inal of the battery is 30 cm (12 in.).
• For the wire size, refer to Connecting the
power terminal. The battery wire, the
ground wire and the optional direct
ground wire must be same size. After
making all other connections at the am-
plifier, connect the battery wire terminal
of the amplifier to the positive 8, term-
inal of the battery.
