[. . . ] Connect all speakers, following the diagrams in this manual. Be sure to observe proper polarity to avoid audio phase problems. Insert fuse(s) into the battery fuse holder(s). Recheck all connections before powering up the amplifier. Set all level controls to minimum position, and set all crossover controls/switches to the desired frequency points. Power up the head unit and the amplifier. 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. Don't misuse the level control! Do not mistake the input level control for a volume control!It is designed ONLY to match the output level of your audio source to the input level of your amplifier. Do not adjust this input level to maximum unless your input level requires it. Ignoring these instructions will result in an input overload to the amplifier, and excessive audio distortion. It can also cause the protection circuit to engage. CHAOS EXXTREME MOSFET Amplifier User's Manual - page 5 Low Level Input Wiring Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! 2-Channel Amplifiers CX250, CX450, CX550, CX750, CX950, and CX1250 Remote Subwoofer Level Control LEFT RIGHT INPUT LEVEL BASS BOOST + L R+ INPUTS CROSSOVER T WO C HA NNE L MOS FE T P OW ER A MP LIF IE R To Audio Outputs of head unit or signal processor 4-Channel Amplifiers CX600, CX650, CX800, and CX1000 Remote Subwoofer Level Control CH 1 CH 2 CH3/4 CONTROLS CH1/2 CONTROLS CH FOUR CHANNEL MOS FE T P OW ER A MP LI FIE R 3 CH 4 CH + 1 CH 2+ CH + 3 CH 4+ INPUTS To FRONT Audio Outputs of head unit or signal processor To REAR Audio Outputs of head unit or signal processor CHAOS EXXTREME MOSFET Amplifier User's Manual - page 6 Low Level Input Wiring Low-level (RCA) input wiring is preferred for best audio performance.

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. Connect the Negative (-) terminal of the subwoofer to the R (-) amplifier terminal. FUSE to REMOTE TURN-ON terminal of head unit Battery CHAOS EXXTREME MOSFET Amplifier User's Manual - page 12 Power and Speaker Wiring Tri-Mode 2-Channel Amplifiers CX250, CX450, CX550, CX750, CX950, and CX1250 Tri-mode operation allows you to connect this amplifier to a pair of main speakers plus a subwoofer on one pair of output channels. The main speakers will operate in STEREO while the subwoofer simultaneously operates in MONO. [. . . ] Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then plug in the component driving the amplifier and unplug its inputs. If the hiss disappears at this point, go on until the faulty/noisy component is found. It is best to set the amplifier's input level control as low as possible. [. . . ]
