ACR-3 Dash Control Installation

The AudioControl ACR-3 dash control is a dual-function remote for 

your Epicenter amplifier. It may be mounted under the dash using its 

own bracket, or through a custom hole in the dash. The endless knob 

should be within reach of the driver, and in a spot where the two LEDs 

are plainly visible. Disconnect the vehicle b12V and Ground 

connections before installation.

Dash Bracket Installation: 

The dash control mounts with two 

screws, which attach to the underside of the dashboard. Slide 

under the dash and place the dash control in its mounting 

position, mark the two best mounting holes, drill pilot holes, and 

secure with two screws.

Custom Installation: 

For that custom, finished look, the dash control 

can be flush-mounted directly on the dashboard (or anywhere 

else). Disassemble the ACR-3 from its mounting bracket. Start by 

pushing the LEDs from their holders, followed by removing the 

circuit board and rotary control knob from the bracket. Carefully 

drill a 9/32” hole in the dashboard for the control, a 1/8” hole for 

the lock tab and two 13/64” holes for the LED holders. Reassem-

ble the dash control components securely onto the dash. 

1.  When the red LED is on, turn the remote knob clockwise to turn 

the subwoofer level up, and counterclockwise to turn it down. 

As it is an endless knob, turning it more than one turn clockwise 

would be maximum, and more than one turn counterclockwise 

is minimum. During the ‘set-up’ part of your installation, make 

sure that the remote knob is turned all the way up in subwoofer 

mode (red LED on) before you make any adjustments to the 

amplifier. In this way you will not overdrive anything if the knob 

was set at a lower level. 

2.  Press the remote knob, and the blue LED turns on and red turns 

off. The knob can now adjust the overall level of the Epicenter 

bass restoration effect. (The sweep and width are set by the con-

trols on the main unit, the remote knob sets its wet/dry level.)
