2. High Level (Speaker) Input from
Factory Radio to Speakers and
Subwoofer
REMOTE LEVEL Controller Connection
The ALC-4 includes a Remote Level control module that provides up to 18dB of gain. This applies to the
Rear Output channel only. The above system diagram gives one possible layout using a 4-channel amplifier
where the rear channel is bridged mono for the subwoofer and the front channels operate a pair of full range
speakers. Once the modular connector is plugged into the REMOTE LEVEL CONTROL and the REMOTE LEVEL
PORT on the ALC-4, you can adjust the output of the signal to the woofer. If your amplifier has its own Remote
Level control or Bass Control do not use that plus the Remote Level control on the ALC-4. Instead just use the
controller that came with the amplifier.
NOTE: More is not always better. By turning the REMOTE LEVEL all the up to MAX (18dB) you can
overwork the amplifier and subwoofer causing potential damage to both.
