The following is a list of tools you will need for installing the Punch amplifier:

Allen wrenches 7/64" & 3/32" (included)

Voltmeter

Wire strippers

Battery post wrench

Electric hand drill w/assorted bits

Wire cutters

Wire crimpers

Assorted connectors

This section focuses on some of the vehicle considerations for installing your new Punch amplifier. Checking your battery and present sound system, as well as pre-planning your system layout and best wiring routes will save installation time. When deciding how to lay out your new system, be sure that each component will be easily accessible for making adjustments.

Before beginning any installation, be sure to follow these simple rules:

1.Be sure to carefully read and understand the instructions before attempting to install the amplifier.

2.For safety, disconnect the negative lead from the battery prior to beginning the installation.

3.For easier assembly, we suggest you run all wires prior to mounting your amplifier in place.

4.Route all of the RCA cables close together and away from any high current wires.

5.Use high quality connectors for a reliable installation and to minimize signal or power loss.

6.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.

7.Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection.

8.Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall.

9.ALWAYS protect the battery and electrical system from damage with proper fusing. Install a fuseholder and fuse on the +12V power wire within 18” (45.7 cm) of the battery terminal.

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.
