5. ect the performance and reliability of your FUSION amplifier For maximum performance we recommend you have your new FUSION amplifier installed by an authorised FUSION dealer Our highly skilled dealers have vast knowledge of our products and their installation techniques are necessary to unleash the high performance capabilities of your amplifier If you decide to connect the amplifier yourself it is important that you read this manual carefully and throughout before starting Once you have finished reading and you still have questions regarding installation we recommend your FUSION dealer Connection FUSION amplifiers are designed to work within a 10 to 16 volt DC range Before any wires are connected the vessel s electrical system should be checked for correct voltage supply with the help of a voltmeter First check the voltage at the battery the voltmeter should read between 12 and 13 8 Volts If your vessel s electrical system is not up to these specification we recommend having it checked by an auto electrician before any further installation Once the vessel is checked make certain the correct cable size is used We recommend using the following cables calculator diagram on page 9 to calculate the correct power cable for your application Power FUSION amplifiers should be wired directly to the battery using the appropriate sized cable Start at the vessels battery and run the power cable through to the amplifier FUSION recommends t
6. he use of grommets when passing the power cable through any metal wall to avoid sharp corners or sharp body parts that may easily cut through the insulation on the cable Avoid running the power cable over engine components The use of an inline fuse or circuit breaker is a must this will prevent the risk of a potential fire caused be a short in your power cable Connect the fuse holder or circuit breaker as close to the battery positive terminal as possible Use a fuse or circuit breaker of equal value as that found on the chassis of your FUSION amplifier You may now connect the cable to the battery but remember to leave the fuse out or circuit breaker off until all other cable connections are made Ground When grounding your FUSION amplifier use the same gauge cable for ground as you did for the power Secure the ground cable to the appropriate ground point now its time to connect the power and ground cables to the amplifier Cut both cables to length Use a hex type screwdriver to loosen the 12V and the GND connections on the amplifier Terminate the ground first and then the 12V and please make sure that you terminate them into the correct terminals Then tighten the screws down securely Speaker Load Keep in mind FUSION AM series amplifiers are high power amplifiers and not high current amplifiers In other words they require a minimum impedance of 2 ohms STEREO and 4 ohms bridged MONO to operate trouble free Too low of an im
