1.12V Constant Power Lead (red): This is the main power input for the 

Vibe 440PSU and must be 

connected to a (+)12V constant power supply. DO NOT connect this to a switched 12V source or 
the system may pop when the key is turned off.

2.Remote Turn-On Input Lead (Blue): This is the input for turning on the 

Vibe 440PSU and system 

amplifiers. It should be connected to the (+)12V remote turn on output of the system head unit. The 

Vibe 440PSU has a built in turn off delay to prevent turn-off pops. When the remote turn on signal 
from the head unit shuts off, the amplifiers will turn off immediately and the 

Vibe 440PSU will stay 

on for five seconds before turning off. This feature is designed into the 

Vibe 440PSU to eliminate 

system turn off pops that can occur when several components turn off at the same time. DO NOT 
connect this to a (+)12V constant power supply.

3.Ground (black): Connect this terminal to a quality ground location, preferably the chassis of the 
head unit, which must itself be properly grounded to the vehicle chassis. It is not recommended 
that the factory radio ground be used for after-market audio components.

5.SOURCE Input: These are the pre-amp stereo RCA audio inputs to be connected to the source 
unit's front pre-amp outputs.

6.AUX Input: These are the pre-amp stereo RCA audio inputs to be connected to secondary source 
unit, or auxiliary device's pre-amp outputs.

8.Front Output: These are the pre-amp stereo RCA audio outputs for sending the audio signal to the 
front speaker amplifier.

9.Rear Output: These are the pre-amp stereo RCA audio outputs for sending the audio signal to the rear 
speaker amplifier.

Plug  the  RCA  output  from  the source unit into the RCA input of the 

Vibe 440PSU. If your 

audio source unit does not have RCA outputs, the 

Vibe 440PSU has the capability to accept high 

level (speaker level)  inputs.
