POWER CONNECTIONS
Connect power to SBP10AMP / SBP12AMP, as shown in Figure 1. Also observe
these installation tips:
Use at least #10 AWG wire for the +BATT (+12Vdc) and GND (ground) connections.
lf needed, use at least a #20 AWG wire for the REM (remote) connection.
Route all power wires through a grommet in the vehicle's firewall. lf a factory
grommet is unavailable, install one.
Connect a short GND wire from SBP10AMP / SBP12AMP to the nearest bare metal
surface. For a good connection, scrape away paint from the metal surface and
use a screw with a lock (star) washer.
Install a fuse holder with a 15A fuse within 18" of the battery's positive (+) terminal
(see Figure 1).
The REM connection requires +5 to +12 Vdc signal to turn on SBP10AMP /
SBP12AMP. Most head units with preamp outputs provide this remote voltage signal.

APPLICATIONS
SBP10AMP / SBP12AMP is equipped with two line-level (RCA) inputs and two
speaker-level inputs.
To help you plan your installation, we have included two system applications in
Figures 2 and 3 on pages 3 and 4. For more system ideas, see your authorized
BOSS car audio dealer.
