A fuse near the The M200/2 can be operated with a wide amplifier is not necessary if the M200/2 is the variety of source units and system configurations. only device being run from the fused main power wire.
M200/2 equipment being run from that power wire. If with 8 or 4 AWG power wire. JL Audio ECS only the M200/2 is being run from that power fused distribution blocks are recommended wire, we recommend a 20A fuse be used.
To use speaker-level sources, simply splice the speaker output wires of the source unit onto a pair of RCA plugs. (or use JL Audio part XD-CLRAIC2-SW) No “line output converter” is needed in most cases. If you find that the output cannot be reduced sufficiently with a direct speaker level signal applied to the amplifier, you may use a “line...
INPUT SENSITIVITY CONTROL The control labeled “Input Sens.” can be used to match the source unit’s output voltage to the input stage of the amplifier for maximum clean output. Rotating the control clockwise will result in higher sensitivity (louder for a given input voltage).

“My amplifier shuts off once in a while, usually at higher volumes.” Check your voltage source and grounding point. The power supply of the M200/2 will operate with charging system voltages down to 10V. Shutdown problems at higher volume levels can occur when the charging system voltage (or remote turn- on voltage) momentarily drops below 10V.
