Supplies and Tools Needed
Supplies:
• Speaker wire (12 gauge for subwoofers, 16-18
gauge for other speakers)
• Sheet metal type screws for mounting amplifier
• Electrical tape
• Solderless crimp connectors
• 1/2" thick plywood or particle board to mount
amplifier on
Tools:
• Flat and Phillips screwdrivers
• Wire cutters
• Wire strippers
• Cordless or standard electric drill and drill bit set
• Crimping tool (if using solderless crimp connec-
tors)
• 12-volt test light or digital multimeter
• Wire brush or scraper (to remove paint for a
good ground connection to vehicle)
• Soldering iron and rosin core solder (if you're
going to solder your connections)
Amplifier Installation Kit:
You will need an amplifier installation kit to install
your amp properly because it contains all the
wire and connectors that you will need to hook
up your new amp right the first time. If you want
to purchase these items separately you will need
the following:
• 20-25 feet of 8 gauge wire
• 30 amp fuse or circuit breaker (to be hooked up
at the battery)
• 20 feet of 18 gauge wire for the remote turn-on/
power antenna lead
• RCA cable (for signal input from radio)
– 20 feet for trunk installation
– 12 feet for under-seat installation
• Two 8 gauge ring terminals (one for the battery
connection and the other for the ground connec-
tion at the amp). You may need two additional
ring terminals if you are using a circuit breaker at
the battery.
• Two 8 gauge barrel connectors (you may need
these depending on what type of fuse holder you
have)
• Two 8 gauge spade terminals (to hook up power
at the amp)
• Four 12 gauge spade terminals for subwoofers or
16-18 gauge spade terminals for other speaker
connections to amp
• One 18 gauge spade terminal for remote turn-on/
power antenna lead

Professional Tip
Bigger is better
Stereo installation dealers sell extra thick
power and speaker wires to ensure best
sound. Look for 8 gauge power wire, espe-
cially if you have several amplifiers.
