Quick Start
Recommended for experienced
professional installers only!
1. Disconnect the negative cable from
the battery. Note: If the vehicle’s
radio features a code type security
system, make certain you know the
code before disconnecting the
battery!
2. Mount the amplifier to the desired
location using four screws.
3. Run a minimum AWG #10 power
cable complete with a 20 amp fuse
(not included) directly from the posi-
tive +12V battery terminal to the
desired amplifier location. Keep
the fuse to within 5" of the battery
terminal, and before the wire runs
through any metal partition.
Note: All wiring connections should be
made either by soldering with heat-
shrink tubing insulation or with high
quality crimp type insulated connectors
installed with a good crimping tool.
Soldering crimp connections is recom-
mended to further enhance connection
reliability. Never use wire-nuts, insula-
tion-displacement connectors (i.e.
ScotchLok type), or “twist and tape”
connections. Do not use electrical tape;
it will loosen with age and extreme
temperatures. Never leave bare wire
exposed.
4. Connect power wiring as shown in
the Wiring Diagram on page 13,
using the supplied power harness.
