Low Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk or hatchback
installations will require a 15-17 foot RCA cable, while pickup trucks and under-seat installations will
require a 6-12 foot RCA cable. Always use a high quality cable.
NOTE: Do not connect BOTH the high level and low level inputs from your head unit to the
amplier at the same time.
High Level Input Wiring
The high level input(s) should only be used when the head unit lacks RCA outputs. If the RCA outputs
are not present, connect the speaker outputs from the receiver to the high level input connector of the
amplier. Be sure to observe correct polarity to avoid audio phase problems.
NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your
amplier at the same time!

Connect the ground terminal to the closest point on the chassis of the vehicle. Keep this ground wire to
less than 39” (100 cm) in length. Use 8 gauge (or heavier) wire. Connect the remote terminal to the
remote output of the head unit using 16 gauge (or heavier) wire. For +12V connect a 30A fuse holder
within 18” (45 cm) of the car battery, and run 8 gauge (or heavier) cable from this fuse to the amplier
location.
