•  NEVER operate the amplifier without proper fusing. Fuse holder must 
be located within 2 feet from the battery. This fuse is to protect the 
vessel, not the electronics. In case of a short, the fuse will blow 
instead of the wire burning up. Using other than the recommended 
fuse ratings at the battery and at the amplifier may cause damage 
to the amplifier and will void your warranty. 
•  To help minimize interference, it is best to run the power cables 
along the side opposite of the audio (RCA) cables. 
•  Whenever wires pass through metal, rubber or plastic grommets 
must be used to prevent the metal from wearing through the 
installation and causing a short. 
•  Whenever possible, use cable ties, mounting clamps and similar 
wiring aids. Adding stress relief loop to wiring is also advisable to 
prevent straining or breakage. 
•  The amplifier operates with any vehicle using a 12 volt negative 
ground system 
•  Remote turn on wire must be switched by the radio. If the radio does 
not have a remote turn on or antenna output, connect to wire that 
has a positive 12 volt output when the key is turned to the accessory 
position. If the amplifier does not turn off the battery will die. 
•  WARNING ! 
Amplifiers may produce sound pressure levels that 
exceed the threshold at which hearing loss may result. Practice 
safe listening when listening to your audio system. When the 
amplifier works in particularly hard conditions it can reach operating 
temperatures above 90˚C/194˚F. Be careful to check the case 
temperature before touching it. This amplifier is developed for 
marine use and has been carefully designed to resist corrosion and 
exposure to humidity.   Please do not expose this Amplifier to liquid 
water at any time. Make sure the amplifier is mounted in a 
clean/dry location.
