The GND terminal grounds the amplifier and is con-
nected to the chassis of the vehicle with 12 gauge, or
heavier, stranded wire. When grounding, scrape paint off
metal to ensure a good, clean ground connection. To
prevent ground loops, we recommend you refrain from
extending the ground wire beyond 18" (46cm) in any
installation.

The Punch 4-Channel amplifiers are turned on by supply-
ing positive (+) 12 volts to the REM terminal. Usually the
terminal is connected to the source unit’s “Accessory” or
“Auto Antenna” lead, either of which will go to +12 Volts
when the source unit is turned on.

when the source unit is turned on.
Although the majority of high-quality automotive source
units have an Accessory or Antenna output, there are
many which require different turn-on methods. If the
source unit has no Auto Antenna lead (or if the Auto
Antenna goes down during tape operation), we recom-
mend a switch in the car with one terminal connected to
+12 volts and the other to the Punch 4-Channel REM
lead. This will allow you to engage the amplifier manually.

The amplifier’s signal input RCA jacks should be con-

quality braided or double-shielded interconnecting RCA
cables.

Note: Be sure to route the Punch 4-Channel signal
input cable away from the main power wire and the
car’s wiring harnesses to avoid noise coupling.
