Shared Amplifier Hookup, 942 | Audio Authority Car Audio System

Shared Amplifier Hookup

This diagram shows one stereo amplifier connected to all three Amplifier Product Groups so that it can play in the front, rear, or sub position. To add three more shared amplifiers, connect each to its own Model 993 adapter, and then connect the adapter to corresponding positions on each 942 module. If some of your amps will be shared, and some not shared, contact Audio Authority® at the phone number below for assistance.

First, mount the switching modules inside your display according to your system plan. Then use the screws provided to mount each amp’s 993 adapter inside the cabinet or on the back of the amplifier display panel near the amplifier to be shared. Connect the Input and Output cables from each 942 module to the 993 adapter as shown. Connect the amplifier to the adapter using the “SHARED AMP” terminals and jacks on the 993. Contact Audio Authority® Technical Service at the phone number below with questions.
