+BAT - 1 . connect this terminal through a FUse or CIRCUIt BReAKeR
to the positive terminal of the vehicle battery or the positive ter-
minal of an isolated audio system battery
WARNING: Always protect this power wire by installing a fuse or
circuit breaker of the appropriate size within 12 inches of the battery
terminal connection .
REM 2 . - this terminal turns on the amplifier when (+) 12 volt is
applied . Connect it to the remote turn on lead of the head unit
or signal source . If a (+) 12 volt remote turn lead is not available,
a Remote Power Adapter (P/n #oRRPA) can be used to supply a
remote turn on signal . Do not connect this terminal to constant
(+) 12 volt
GND -
3 . power return connection . Connect this terminal directly
to the sheet metal chassis of the vehicle, using the shortest wire
necessary to make this connection . Always use wire of the same
gauge or larger than the (+) 12 volt power wire . the chassis con-
nection point should be scraped free of paint and dirt . Use only
quality crimped and/or soldered connectors at both ends of this
wire . Do not connect this terminal directly to the vehicle battery
ground terminal or any other factory ground points
