PRODUCT DESCRIPTION

The JL Audio XD700/5v2 is a five-channel, 

system amplifier utilizing JL Audio NexD™ ultra 
high speed switching technology for its four main 
channels and NexD™ high-speed switching for 
its subwoofer channel. The NexD™ technologies 
deliver outstanding fidelity and efficiency.

The XD700/5v2 can be operated with a wide 

variety of source units and system configurations.

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence 

for a typical amplifier installation, using an 
aftermarket source unit or OEM Interface 
processor (like the CleanSweep CL441dsp). 
Additional steps and different procedures may 
be required in some applications. If you have any 
questions, please contact your authorized  
JL Audio dealer for assistance. 
 

 1)

  Disconnect the negative battery post 

connection and secure the disconnected cable 
to prevent accidental re-connection during 
installation. 

This step is not optional.

 2)

  Run 4 AWG power wire from the battery 

location to the amplifier mounting location, 
taking care to route it in such a way that it will 
not be damaged and will not interfere with 
vehicle operation. Use 2 AWG or larger power 
wire and a fused power distribution block if 
additional amplifiers are being installed with 
the XD700/5v2.

 3)

  Connec wer wire to the positive battery post. 

Fuse the wire with an appropriate fuse block 
(and connectors) within 18 inches (45 cm) 
wire length of the positive battery post. 

This 

fuse is essential to protect the vehicle.  
Do not install the fuse until the power wire 
has been securely connected to the amplifier.  

 4)

  Run signal cables and remote turn-on wire 

from the source unit to the final amplifier  
mounting location.

 5)  

Run speaker cables from the speaker systems 
to the amplifier mounting location.

 6)

  Find a good, solid metal grounding point 

close to the amplifier and connect the 
negative power wire to it using appropriate 
hardware (use of the JL Audio ECS master 
ground lug, XB-MGLU is recommended). 
Use 4 AWG wire, no longer than 36 inches 
(90 cm) from the amplifier to the ground 
connection point. In some vehicles, it may 
be necessary to upgrade the battery ground 
wire. (See page 5 for important notice). 

 7)

  Securely mount the amplifier.

 8)

  Connect the positive and negative 

power wires to the amplifier. A fuse 
near the amplifier is not necessary if 
the XD700/5v2 is the only device being 
run from the fused main power wire. 
If the fused main power wire is shared 
by the XD700/5v2 and other amplifiers 
or devices, fuse each amplifier/device 
within 12 inches (30 cm) of wire length, 
via a fused distribution block or multiple 
individual fuse blocks/on-board fuses.   

 9)

  Connect the remote turn-on wire to the 

amplifier or configure the 

“Turn-On Mode”

 

switch for automatic turn-on. 

10)

 Connect the input cables to the amplifier.

11) 

Connect the speaker cables to the amplifier.

12)

  Carefully review the amplifier’s control  

settings to make sure that they are set 
according to the needs of the system.

13)

  Install the power wire fuse (60A for a single 

XD700/5v2) and reconnect the negative 
battery post terminal. Install the fuse (60A) 
near the amplifier (if applicable).

14)

  Turn on the source unit at a low level to 

double-check that the amplifier is configured 
correctly. Resist the temptation to crank it up 
until you have verified the control settings.

15

)  Make necessary adjustments to the 

input sensitivity controls to obtain the 
right overall output and the desired 
balance in the system. See Appendix 
A (page 16) for the recommended 
input sensitivity setting method.

16)

  Enjoy the fruits of your labor with your 

favorite music.
