User manual BOSS CHAOS SE3500D

[. . . ] The current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2 Ohm load. If you lack adequate current, your music reproduction will be distorted. CHAOS WIRED Amplifier User's Manual - page 3 General precautions Before installing and using your new amplifier, please become familiar with all the information contained in this manual. Please keep this manual in a safe place for future reference. · Do not open or attempt to repair this unit yourself. [. . . ] Make sure there is sufficient air circulation around the intended mounting location. Mark the location for the mounting hole screws by positioning the amplifier where you wish to install it. Use a scribe or mounting screw, inserted through each of the amp's mounting holes, to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen. Drill pilot holes in the mounting surface for the mounting screws. Place the amplifier in position, and attach the amplifier to the mounting surface securely using screws. CHAOS WIRED Amplifier User's Manual - page 5 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. Be sure you understand all the connections before you proceed. Connect the power ground terminal to the closest point on the chassis of the car. Keep this ground wire to less than 39" (100 cm) in length. 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 8 gauge (or heavier) cable from this fuse to the amplifier location. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! 2-Channel Amplifier CW150 R+ R- L- L+ To Speaker Terminals of head unit 4-Channel Amplifier CW350 CH4+ CH3CH3+ CH2+ CH1CH1+ CH4- CH2- To Speaker Terminals of head unit CHAOS WIRED Amplifier User's Manual - page 8 Power and Speaker Wiring 2-Channel Amplifier CW150 ­ + ­ + RIGHT Speaker LEFT Speaker SPEAKER IMPEDANCE 2-8 OHMS Chassis ground point to REMOTE TURN-ON terminal of head unit 4-Channel Amplifier CW350 CH1 Speaker FUSE Battery CH2 Speaker SPEAKER IMPEDANCE 2-8 OHMS CH4 Speaker Chassis ground point to REMOTE TURN-ON terminal of head unit SPEAKER IMPEDANCE 2-8 OHMS CH3 Speaker FUSE Battery CHAOS WIRED Amplifier User's Manual - page 9 Troubleshooting If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous pages. If problems persist, read the following troubleshooting tips which may help eliminate the problems. POSSIBLE REMEDY Check to make sure you have a good ground connection. Check that the Remote Input (Turn-On) has at least 3VDC. Check that there is battery power on the (+) terminal. Make sure that the Protection LED is not illuminated. If it is lit, shut off the amplifier briefly, and then repower it. Check for short circuits on speaker leads. Turn down the volume control on the head unit to prevent overdriving. Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty and needs servicing. [. . . ] Check for short circuits on the speaker leads. Check that the minimum speaker impedance for the amp model is correct. Check that there is good air circulation around the amp. In some applications, it may be necessary to add and external cooling fan. [. . . ]
