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.
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- nected to the source unit’s signal outputs with high- 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.
