INTRODUCTION The Rockford Punch 30, Punch 45, Punch 75 and Punch 150 are automotive stereo power amplifiers which will provide state-of-the-art sound in cars, vans, boats, or wherever a 12 volt battery is available. The Punch adjustable input circuits are designed to match almost any music source, from low preamp levels to speaker levels, with negligible noise. -
Page 5: Input Level Controls
INPUT LEVEL CONTROLS The Punch input level controls are accessible with a jeweler’s screwdriver through two holes in the cover. The controls are factory-preset to a level which matches most 500 millivolt to 1 volt rated preamp-output source units. If you are using the speaker - output leads of the source unit, turn the Punch input controls fully counterclockwise to their minimum gain position. -
Page 6: Turn On Connection
“Accessory” or “Auto Antenna” lead, either of which will go positive when the source is turned on. (Note: The Punch 30 is turned on by applying 12 volts to the REM terminal.) Although the majority of high quality automotive source units have an Accessory or Auto Antenna output, there are many which may require different turn-on methods. -
Page 7: Speaker Impedance
SPEAKER IMPEDANCE The Punch is rated for operation into loads of 2 Ohms or greater in stereo operation. The primary loads on the amplifier come from directly connected speakers (not isolated by capacitors), and the measured resistance for each side cannot be less than 1.8-Ohms. Single 4-Ohm woofers or parallel 4-Ohm pairs per side will form a high performance system. -

Page 10: Protection Circuits And Fusing
PUNCH 30 MOSFET PROTECTION AND FUSING The Punch30 is protected by two 3-Ampere speaker-line fuses and by a 7-Ampere battery fuse. A thermal sensor shuts down the amplifier in case of overheating. Internal circuitry shuts down the amplifier in case of overload. -
Page 11: Battery And Charging System
TRUNK MOUNTING We have measured trunk temperatures as high as 175 degrees Fahrenheit in the summertime. Since the thermal shutoff point for the Punch is 195 degrees F, it is easy to see that the amp must be mounted for maximum cooling capability. Mounting the amp on the floor or roof of the trunk will not allow convection air flow. -

26 dBV (correct for most 500 millivolt-rated source units). PROTECTION: The Punch 30 MOSFET is protected by two 3-Ampere speaker-line fuses and by a 7-Ampere battery fuse. A thermal switch shuts down the amplifier in case of overheating. Internal circuitry limits power in case of o v e r l o a d . -
