User manual BOSS CHAOS SE250

[. . . ] This new series includes a two monoblock amps, six 2-channel, four 4-channel amplifiers and a 5-channel amp. All CHAOS EXXTREME models feature variable low pass and high pass crossovers and variable input gain controls. They also incorporate an input voltage sensistivity selector for added system flexibility. For further flexibility in the use of a subwoofer, 0-+18dB Bass Boost control has been included on all amplifiers. [. . . ] 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. Then connect the fuse holder to the "BATT+" connection on the amplifier. If multiple amplifiers are being used in your system, either: · Run a separate pair of cables from the battery and a chassis ground point to each amplifier. Each (+) cable must have its own inline fuse. -or· Run a #4 cable from the fuse holder at the battery to a distribution block at or near the amplifier's location. 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. Connect all speakers, following the diagrams in this manual. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! 5-Channel Amplifier CX1800 CH1+ CH1- CH2- CH2+ Remote Subwoofer Level Control To Speaker Terminals of head unit CH1/2 CONTROLS CH 1 CH 3 INPUT CONTROLS CROSSOVER BASS BOOST CH 5R INPUT CONTROLS CROSSOVER +1 CH CH CH 2+ 4+ CH + 3 CH 2 CH 4 INPUT CONTROLS CROSSOVER BASS BOOST CH 5L INPUT MODE BASS BOOST CH5 CH5 CONTROLS CH3/4 CONTROLS CH3+ CH3- CH4- CH4+ To Speaker Terminals of head unit CHAOS EXXTREME MOSFET Amplifier User's Manual - page 10 High Level Input Wiring The high level input(s) should only be used when your head unit lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems.

The main speakers will operate in STEREO while the subwoofer simultaneously operates in MONO. To set up the amplifier to run in this mode, put the crossover switches in the FULL position. Insert high pass filter capacitors and a low pass filter inductor into the wiring as shown below. Be sure to check the table at the bottom of this page to determine the correct capacitor and inductor values for the crossover frequency you wish to achieve.

Check that amplifier is properly grounded. Check that the Remote Input (Turn-On) has at least 3VDC. Check that the RCA audio cables are plugged into the proper inputs. [. . . ]
