An aftermarket audio amplier will place an additional load on the vehicles charging system.
Most modern vehicles have sufcient capacity in the charging system as not all the electrical
components of the vehicle will be switched on at once.
Check the fuse rating of the amplier and use this as the peak current requirement.
Generally the continuous current draw will be a third of the peak current.

During the normal use of this amplier the heatsink may become very hot.
Please do not touch during or immediately after use.

MOUNTING GUIDELINES
Your FLI amplier is designed with a swift installation routine in mind.
Please mount the amplier in a dry location on a solid surface.

eventually damage the amplier.
Before xing the amplier in place please ensure that there is sufcient air ow around the exterior of
the casing, at least two inches is sufcient.
POWER CONNECTIONS
POWER CABLE
• At least 8 gauge cable should be used for the power connection to the amplier.
• The power cable should be taken directly from the battery. Rubber grommets should be used when
passing through any bulkheads to prevent the cable from becoming chaffed or cut.
• It is vital that a fuse / circuit breaker (of at least equal value to the one tted on the amplier) is
placed inline with the power cable and is no further than eighteen inches away from the battery and
must be tted before the wire passes through the bulkhead / rewall.
• Please ensure that the fuse is not tted until the entire installation procedure is complete.
• The two tables overleaf are to help you decide on what cable is correct for you. The rst enables
you to select the size of cable depending on the length required. The second will help you convert
the cable size from American Wire Gauge to Metric and Imperial if you need to.

GROUND CABLE
• At least 8 gauge cable should be used for the ground connection to the amplier.
• The amplier ground should be connected directly to the chassis of the vehicle, to bare metal.
• The cable length should be kept to an absolute minimum.
• It is not recommended that you connect the ground cable to the vehicles seatbelts anchor point.
REMOTE TURN ON CABLE
• A minimum of 18 gauge cable should be used for this connection.
• The cable should be run with exactly the same care and attention as the power cable and taken
back to the source (headunit) and joined to the remote cable provided.
• If the source (headunit) does not have a remote turn on cable then a 12v supply should be used.
This will require a switch to be tted inline to enable the amplier to be turned on and off.
Remember that if this switch is left on you will atten the car battery.
RCA CABLES
• Depending on the model number of your amplier and the number of speakers you wish to
power you will have to run either one, or two RCA cables from the source to the amplier.
• Please take extra care when running these cables from the source to the amplier. Ensure that
they are placed away from all items that can generate any electrical interference, wiring harnesses
etc.
• It is recommended that the RCA cables should be run on opposite sides of the car to the
previously installed power cables if possible, to avoid the cable picking up interference.
