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 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. 2 AWG or larger is recommended 
for wire runs greater than 72 inches (180 
cm) in length. This 2 AWG wire  needs 
to be reduced to 4 AWG within 36 wire 
inches of the amplifier using a distribution 
block. Use a 1/0 AWG or 1/0 AWG main 
power wire with a fused power distribution 
block when additional amplifiers are being 
installed with the HD1200/1 and are being 
powered from the same main power wire.  

  3)  Connect power 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 connected to the amplifier. 

  4)  Run signal cables (RCA cables) and remote 

turn-on wire from the source unit or interface 
processor to the amplifier mounting location. 

  5)  Run speaker wire from the speaker systems to 

the amplifier mounting location.

  6)  Find a good, solid, bare metal grounding 

point close to the amplifier and connect the 
negative power wire to it using appropriate 
hardware. Use minimum 4 AWG power wire, 
no longer than 36 inches (90 cm). In some 
vehicles, it may be necessary to upgrade the 
battery’s ground wire as well. (See pages 6, 7 
for important notice).

  7)  Securely mount the amplifier using 

appropriate hardware. (See page 8 for detailed 
mounting instructions).

  8)  Connect the remote turn-on wire and the 

positive and negative power wires to the 
amplifier’s power connector plug. Then insert 
the power connector plug into the amplifier’s 
power connector receptacle, pushing firmly.

  9)  Connect the RCA input cables  

to the amplifier.

10)  Connect the speaker wires to the speaker 

connector plug and insert the plug firmly into 
the speaker connector receptacle.

11)  Carefully review the amplifier’s control  

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

12)  Install power wire fuse (100A for a  

single HD1200/1) and reconnect the negative  
battery post terminal.

13)  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.

14)  Make necessary adjustments to the input 

sensitivity controls to obtain the right  
overall output and the desired balance  
in the system. See Appendix C (pages 18, 19)  
for the recommended input sensitivity  
setting method.

15)  Enjoy the fruits of your labor with your 

favorite music.
