POWER CONNECTIONS

Before installing the amplifier, disconnect  

the negative (ground) wire from the vehicle/ 

vessel’s battery. This will prevent accidental 

damage to the system, vehicle/vessel and  

your body during installation.

NOT FOR USE IN 12V SYSTEMS!

The M800/8-24V’s “+24 VDC” and “Ground” 

connections are designed to accept up to 4 AWG  

power wire. 4 AWG is the required wire size for 

this amplifier. 

If you are installing the M800/8-24V with 

other amplifiers and wish to use a single main 

power wire, use 2 AWG or 1/0 AWG main power 

wire (depending on the overall current demands 

of all the amplifiers in the system). This 2 or 

1/0 AWG power wire should terminate into a 

fused distribution block mounted as close to 

the amplifiers as possible (within 12 inches / 

30cm of wire length). The fused output of the 

distribution block will connect to the M800/8-

24V with 4 AWG power wire.  JL Audio ECS 

fused distribution blocks are recommended 

(XD-FDBU-2 and XD-FDBU-4)

Note: Smaller AWG numbers mean bigger 

wire and vice-versa (1/0 AWG is the largest, 2 

AWG is smaller, then 4 AWG, then 8 AWG, etc.).

 To connect the power wires to the amplifier, 

first back out the set screw on the top of the 

terminal block, using the supplied 2.5 mm hex 

wrench. Strip 1/2 inch (12 mm) of insulation from 

the end of each wire and insert the bare wire into 

the terminal block, seating it firmly so that no 

bare wire is exposed. While holding the wire in 

place, tighten the set screw firmly, taking care not 

to strip the head of the screw.

The ground connection should be made using 

the same gauge wire as the power connection.

Any wires run through barriers must be 

protected with a high quality rubber grommet 

to prevent damage to the insulation of the wire. 

Failure to do so may result in a dangerous  

short circuit. 

 

Many vehicles/vessels employ small (10 AWG - 

6 AWG) wire to connect the alternator’s 

positive connection to the battery and ground 

connection to the chassis or battery. To 

prevent voltage drops, these wires should  be 

upgraded, where possible, to 4 AWG when 

installing amplifier systems with main fuse 

ratings above 60A.

FUSE/CIRCUIT BREAKER REQUIREMENTS

It is absolutely vital that the main power 

wire(s) to the amplifier(s) in the system be 

fused within 18 inches (45 cm) of the positive 

battery post connection. The fuse value at each 

power wire should be high enough for all of the 

equipment being run from that power wire. If 

only the M800/8-24V is being run from that 

power wire, we recommend a 40A fuse or circuit 

breaker be used. 

If fusing the amplifier near its power 

connections (when more than one amp is being 

run from the main power wire), use a 40A fuse.

MAXI™ (big plastic-body) fuses or JL Audio 

marine-grade circuit breakers are recommended.
