may be used as a remote turn-on source for other 
amplifiers in the system. +12V will be present  
at the connector when the amplifier turns on in

the amplifier turns off. 

 

 

 

The 600/1v3 employs a differential-balanced  

input topology that provides the user with a high 
degree of input flexibility while retaining superior 
noise rejection. This type of circuit also allows 
the 600/1v3 to accept high-voltage inputs from 
factory source unit outputs without excessive 
distortion or noise problems.

1)  Input Connections:  A standard left/right pair 

of RCA type jacks is used for input on  
the 600/1v3. You may run a stereo or a mono  
signal into the inputs of the amplifier. The 
amplifier’s input section automatically sums  
stereo signals to mono for the internal

The amplifier will operate with only one input 

connection (left or right), but will require an 
increase in input sensitivity to overcome the loss 
of signal. If a mono input signal is to be run, we

the mono signal into both inputs of the amplifier.

 

2)  Input Voltage Range:  A wide range of 

signal input voltages can be accommodated 
by the 600/1v3’s input section (200mV – 8V). 
This wide range is split up into two sub-

The chassis ground connection must be made 

using 4 AWG pure copper wire and should be 
kept as short as possible, while accessing a solid 
piece of sheet metal in the vehicle. The surface of 
the sheet metal should be sanded at the contact 
point to create a clean, metal-to-metal connection 
between the chassis and the termination of 
the ground wire with a brass or copper power 
ring. For optimal grounding, we recommend 
the use of a JL Audio ECS master ground 
lug (XB-MGLU). Alternatively, a sheet metal 
screw or bolt can be used with a star washer.

 

The 600/1v3 can be turned on and off using 

two different methods: 

 

1) A conventional +12V remote turn-on lead. 
2) A signal sensing turn-on circuit.

1)  Conventional Remote Turn-On Method: 

uses a conventional +12V remote turn-on 
lead, typically controlled by the source unit’s 
remote turn-on output. The amplifier will

input and turn off when +12V is switched 

off. If a source unit does not have a dedicated 
remote turn-on output, the amplifier’s turn-on 
lead can be connected to +12V via a switch 
that derives power from an ignition-switched

turn-on connector is designed to accept 12 
AWG – 8 AWG wire. 12 AWG is more than 
adequate for this purpose. To connect the 
remote turn-on wire to the amplifier, first back 
out the set screw on the top of the amplifier, 
using the supplied hex wrench. Strip 1/2 
inch (12mm) of wire and insert the bare wire 
into the receptacle on the front panel of the 
amplifier, seating it firmly so that no bare wire 
is exposed. Smaller wire than 12 AWG can be 
used, but it may be necessary to strip 1 inch 
of insulation from the wire and fold the bare 
wire in half prior to insertion. While holding 
the wire in the terminal, tighten the set screw 
firmly, taking care not to strip the head of the 
screw and making sure that the wire is firmly 
gripped by the set screw.

 

2)  Signal Sensing Turn-On Method: A valuable 

feature of the 600/1v3 is its ability to be turned 
on and off by the presence or lack of signal at 
its audio inputs. This allows you to operate the 
amplifier without having to locate a remote 
turn-on lead at the source unit. This can be 
very useful if interfacing the amplifier with 
some OEM source units that do not have 
conventional turn-on leads.
