If you don't have the proper tool, you should either buy it, or
take your car to a qualified installer.
Protect the vehicle
Always disconnect the negative battery cable before starting any kind of
installation work. This prevents a possible high current electrical
short (potential fires).
Be aware of the heat
Keep all audio components away from nearby hot vehicle components that
heat up over time such as hoses, high current wires, and braking system
components.

Take your time
Rushing yourself almost always leaves room for mistakes, frustration,
and a sloppy install. If you're installing an entire
audio system, give
yourself at minimum 1-2 days.
Review the installation
Before using any tools or
moving vehicle components, take five minutes to review the installation
intentions.
