CAUTION:If you feel unsure about installing this system yourself, have it installed by a
qualified technician.
CAUTION:Before installation, disconnect the battery negative (-) terminal to prevent
damage to the unit, fire and/or possible injury.
Before beginning any installation, follow these simple rules:
Be sure to carefully read and understand the instructions before attempting to install the unit.
For safety, disconnect the negative lead from the battery prior to beginning the installation.
For easier assembly, we suggest you run all wires prior to mounting your unit in place.
Route all of the RCA cables close together and away from any high current wires.
Use high quality connectors for a reliable installation and to minimize signal or power loss.
Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines,
vacuum lines or electrical wiring when working on any vehicle.
Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best
Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any
wires routed through metal, especially the firewall.
ALWAYS protect the battery and electrical system from damage with proper fusing. Install the
appropriate fuse holder and fuse on the +12V power wire within 18" (45.7 cm) of the battery
10. When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good, clean
ground connection. Grounding connections should be as short as possible and always be connected to
metal that is welded to the main body, or chassis, of the vehicle.


Engine Compartment
Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will void
your warranty.
Trunk Mounting
Mounting the amplifier vertically will provide adequate cooling of the amplifier.
Mounting the amplifier on the floor of the trunk will provide the best cooling of the amplifier.
Mounting the amplifier upside down to the rear deck of the trunk will not provide proper cooling and will
severely affect the performance of the amplifier and is strongly not recommended.
Passenger Compartment Mounting
Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount
of air for the amplifier to cool itself. If you are going to mount the amplifier under the seat of the vehicle,
you must have at least 1" (2.54cm) of air gap around the amplifier's heatsink.
Mounting the amplifier with less than 1" (2.54cm) of air gap around the amplifier's heatsink in the
passenger compartment will not provide proper cooling and will severely affect the performance of the
amplifier and is strongly not recommended.


Amplifiers will put an increased load on the vehicle's battery and charging system.We recommend
checking your alternator and battery condition to ensure that the electrical system has enough capacity to
handle the increased load of your stereo system. Stock electrical systems which are in good condition
should be able to handle the extra load of any Punch Series amplifier without problems, although battery
and alternator life can be reduced slightly.To maximize the performance of your amplifier, we suggest the
use of a heavy duty battery and an energy storage capacitor.
