Thank you for purchasing this FLI amplifier. It will provide you with a lifetime of trouble free use
providing you follow a few simple guidelines.
Mounting Guidelines
Your FLI amplifier is designed with a swift installation routine in mind. Please mount the amplifier in a dry location on a solid
surface. NEVER mount the amplifier upside down, this will cause the amplifier to over heat and will eventually damage the
amplifier. Before fixing the amplifier in place please ensure that there is sufficient air flow around the exterior of the casing, at
least two inches will be sufficient.
Connections
Power Cable
O
At least an 8 gauge cable should be used for both the power and the ground connections to the amplifier.
O
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.
O
It is vital that a fuse / circuit breaker (of at least equal value to the one fitted on the amplifier) is placed in line with the
power cable and is no further than eighteen inches away from the battery.
O
Please ensure that the fuse is not fitted until the entire installation procedure is complete.
O
The two tables below are to help you decide on what cable is correct for you. The first 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 if you need to.
