User manual BOSS CHAOS EXXTREME CX3500D

[. . . ] Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Attach all audio system components securely to prevent damage, especially in an accident. [. . . ] Then run separate cables from the amplifier to this distribution block and to independent chassis ground points. Connect all line inputs and outputs (if used) using high-quality cables. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points. Then set the volume control on the head unit to about 3/4 volume, and adjust the amplifier's input level control(s) to just below the level of distortion. Further fine tuning of the various controls may be necessary to obtain best results. Connecting the amplifier Before doing any wiring, look through this manual and identify the diagrams to follow for power, input and speaker connections for your particular installation. Connect the amplifier's power ground terminal to the closest point on the chassis of the car. Connect the remote terminal to the remote output of the head unit using 16 gauge (or heavier) wire. Connect an empty fuse holder within 18" (45 cm) of the car battery, and run 4 gauge (or heavier) cable from this fuse to the amplifier location. The purpose of placing a fuse in this location is to protect your vehicle's battery in the event that this wire accidentally touches the chassis ground on its run to the amplifier. CX2500D · CX3500D Amplifier User's Manual - page 4 Important installation considerations for using this amplifier. Your CHAOS EXXTREME Class D amplifier is designed to run with a minimum load of 1 Ohm. Operating the CX2500D or CX3500D with a speaker impedance load below 1 Ohm may result in poor sound quality and damage to the amplifier circuitry. Such damage is not covered under the warranty for this product. The fuse ratings for these amps is 40A (using two 20A fuses) for the CX2500D and 90A (using three 30A fuses) for the CX3500D. Although sufficient for normal working conditions, overloading the amp may result in blown fuses. [. . . ] Check that the minimum speaker impedance for the amp model is correct. In some applications, it may be necessary to add and external cooling fan. [. . . ]
