Active enclosure Installation
Your FLI UNDERGROUND enclosure is designed with a swift installation routine in
mind. Please mount the enclosure in a dry location on a solid surface. NEVER mount the
enclosure upside down, this will cause the amplifi er to overheat and will eventually damage
the amplifi er. Before fi xing the enclosure in place please ensure that there is suffi cient air
fl ow around the amplifi er heatsink, at least two inches will be suffi cient.
Power Cable
• At least a 10 gauge cable should be used for both the power and the ground connections to the
amplifi er.
• 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 fi tted on the amplifi er) is placed
in line with the power cable and is no further than eighteen inches away from the battery.
• Please ensure that the fuse is not fi tted until the entire installation procedure is complete.
• The two tables below are to help you decide on what cable is correct for you. The fi 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 if you need to.
