Do not install where it will be directly exposed to the elements. To optimize performance, avoid confined installation locations or areas surrounded by metal; maintain at least 25 cm (10 in) of separation from any audio signal cables. Make sure the total amperage demands of all connected LED circuits does not exceed the output capacity of the controller. *Install a fuse (not included) at the main +12V power wire (Red) connection point that is appropriate for the total current draw of all LED circuits (up to 10 A). For short-circuit protection, we recommend installing a fuse (not included) at EACH speakers +12V LED connection lead. Refer to your speakers LED specifications for individual fuse values.
