For optimal performance, Memphis recommends using only Memphis Connection accessories. Outfitting your system with properly sized Memphis Connection wire and accessories will dramatically boost your listening experience and increase the durability of your Memphis Audio products.
Factory OEM integration has never been easier. The LL6SA allows you to add multiple amplifiers and signal processors while retaining your factory head unit and volume controls. The LL6SA’s summing feature decodes complicated factory signals with built-in crossovers and converts them into a flawless preamp signal.

Operation and Function
-
A. POWER CONNECTIONS
These connections are for 12V+ input power, chassis ground and remote turn-on. Use a minimum of 18 AWG wire for power and ground connections. Power wire should be protected with a 1 amp fuse. -
B. INPUT LEVEL ADJUSTMENTS
These controls are used to match the input level of your LL6SA with the output level of your source unit -
C. POWER INDICATOR
This LED indicates your LL6SA is powered ON -
D. SUMMING INDICATORS
These LEDs indicate when a channel is being summed with, or connected to the main channel. -
E. RCA OUTPUTS
These low-level output jacks provide a full range signal to your amplifier(s) -
F. AUX INPUT
This RCA input jack allows you to connect an additional source such as a phone to the LL6SA -
G. REMOTE CONTROL
The indicator light on the remote control will light up when the power is on. The self-lock switch is for source selection. Push the self-lock switch to switch between the main (head unit) and the AUX input on the LL6SA. Rotate the control knob on the remote to adjust the output level of the sub channel on the LL6SA -
H. High Level Inputs
Each terminal block allows for up to 100w of speaker level signal to be input from the source unit. All three are full-range inputs.
Installation
Memphis Audio always recommends any installation be performed by an authorized Memphis Audio dealer. If you elect to perform your own installation, please read the manual very carefully. Failure to do so may compromise the integrity of this product, your automobile, and possibly void the product warranty. Before securing the LL6SA, inspect the mounting location to ensure you do not drill into or damage any electrical, hydraulic, fluid or fuel lines.
Power Supply Connections
Use conventional copper-stranded wire for all connections. Finish all the ends wire at the amp and vehicle connections with the proper size terminals. Poorly made connections or frayed or loose wires may generate excessive heat, short circuit and potentially lead to system failure.
POWER CONNECTIONS (+12V & GND)
- The +12V terminal should be connected to the POSITIVE +12V power using a 1 A fuse between the power source and the LL6SA.
- The GND terminal should be connected to the chassis ground and should have a ring terminal crimped and soldered and should be connected to the chassis of the vehicle in an area free of debris. Paint should be stripped and cleaned for a sound connection.
REMOTE IN
The LL6SA is turned on by applying +12V DC to this terminal. Connect the
REMOTE terminal to the lead or power antenna wire from the head unit. If the
head unit doesn’t provide a remote turn-on, you can use the accessory terminal
in the car’s fuse block. Using this method will turn off the LL6SA with the
vehicle’s ignition key regardless of whether the head unit is on or off.
REMOTE OUT
The LL6SA is equipped with a signal sensing circuit that is designed to detect
a signal on its input to both turns on the LL6SA and provide a +12V output
signal to turn on an after-market amplifier. Connect this terminal to the
remote terminal (turn on lead) of your amplifier. If more than one amplifier
is being used with the turn-on output of this unit, a relay must be used.
Internal Switch/Jumper Options
Isolation Jumper
Occasionally alternator noise may appear in a system because the source unit
and amplifier are using different grounding schemes. To help in this
situation, we have provided alternative grounding connections. Make sure your
system is turned OFF before you move these jumpers. The LL6SA is shipped in
the isolated position.
You have 3 options jumper selections:
- Isolated
- 200 ohm
- Ground
Blending Switch:
The LL6SA contains switches that will allow you to sum selected channels into
the main channels. This is especially useful for factory-installed systems
with actively crossed-over speaker systems. The switches allow you to select
which input signals will be summed into the Main outputs. When the switch is
in the blended (Summed) position, there will also be a corresponding green
indicator light on the front of the LL6SA. The shipped-from-the-factory
setting is in the direct position.
