The GND terminal grounds the amplifier and is connected to the chassis of the vehicle with 12 gauge, or heavier, stranded wire. To prevent ground loops, we recommend you refrain from extending the ground wire beyond 18" (45.72cm) in any installation. The ends of the Power and Ground wires that are connected to the amplifier should be stripped back 5/8” (1.59cm).

The Punch amplifiers are turned on by supplying 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):

a.Find the internal switched power voltage inside the source unit and solder a lead to it. Run the lead out through the back of the unit (being sure to use a grommet for insulation from the case) and connect the Punch remote turn-on wire; or:

b.Install a switch in the car with one terminal connected to +12 volts and the other to the Punch lead.

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 signal input cable away from the main power wire and the car’s wiring harnesses to avoid noise coupling.

Punch amplifiers are rated for safe operation into loads of 2Ω or greater in stereo mode or 4Ω in bridged mono configurations. The primary loads on any amplifier come from directly connected speakers without using capaci- tors. The measured resistance for each side should not be less than 2Ω .
