to the bare metal using a bolt, star washer and nut. Seal the area from above
and below to prevent rust. Strip approximately 1/2 inch of insulation from the
other end of the cable and insert it into the ground block on the amplifier and
tighten the Allen screw.

For multiple amplifier systems, a ground distribution block is recommended.
Cut a length of cable long enough to go from the ground distribution block to
the amplifier. Strip approximately 1/2 inch of insulation from each end of the
ground cable. Insert one end into the ground distribution block and tighten the
Allen screw. Insert the other end of the cable into the ground block on the
amplifier and tighten the screw (A ring terminal may be used here). Repeat for
each amplifier installed. Run a cable (the same gauge as the main power cable)
from the ground distribution block to the negative terminal of the system
battery.
Your
D7 Professional Reference Series Amplifier
is designed to accept up to
4 gauge power and ground cable when using the Direct (stripped wire end)
Connection method.
When using ring terminals to attach the power and ground, cables of up to 1/
0 gauge can be used. Please refer to the Power Cable Gauge Chart (page 7) for
the minimum recommended wire gauge.
