Connect the power wire to the battery using a fuse capable of the total
current load of all amplifiers connected. Don’t install the fuse yet. Wait
until the end. Locate the fuse as close as possivle to the battery. If the fuse
is further than 18 inches (wire lenght) from the battery you should reevaluate
the wire and fuse placement.
Find the closest clear metal area to the amp for a ground, sand, grind or scrape
all paint and undercoating from the body and screw the ground securely in place.
It is advisable to test the ground with an ohmmeter between the ground cable
and the negative battery cable to insure a good low resistance connection.
Some alloys used in modern cars do not offer the best ground. If you believe
this is the case consult with the vehicle manufacturer.
Run the speaker wire to the speakers. It is adviced that you leave some extra
wire at this point. You can “clean it up” later.
If you haven’t already done so, mount the amp now.
Connect the power and ground to the amplifier.
Only after this step should you install the fuse at the battery.
Connect the remote wire from the head unit to the amplifier. Now is a good time
to turn on the amp for the first time. Make sure it turns on properly and does not
go into protection.
Connect the speaker wires to the amp and speakers (make sure the amp is off
first). Make sure the polarity (+and-) is correct.
Connect the RCA’s to the amp.
Double check the amplifier controls at this time. Make sure everything is set
correctly for your system.
Now you’re ready to play it for the first time. It is best to leave the gain all the
way down at first. Start with the head until volume low and work your way up.
Now you can tune the amp. Take your time and make only one adjusment at a
time. It may take some time to get the system fully adjusted. During this time
the amp is drawing current from the battery. You should check the battery
voltage from time to time and re-charge it if it gets low. That’s it. You’re done.
Now have fun.
