Installation Instructions

The professional way to integrate 

your new amplifier.

General Overview 

Install It Right with L.O.C. PRO

  

Don’t cheat yourself out of all the performance your new radio or amplifier can deliver. Proper audio line level 
matching is critical when replacing your vehicle’s factory (OEM) radio or amplifier. It can be the difference 
between a great sounding system that you enjoy every day and a buggy, noisy mess that drives you crazy.   
PAC L.O.C.PRO™ interfaces have been professionally designed for those who want the very best.

The L.O.C.PRO™ LP3-2 can be used for adding amplifiers to a system that does not have RCA outputs. Level 
matching is achieved using precision stereo gain dials and will enable proper adjustment of audio output of the 
radio for optimum system performance. Included in these instructions are the most common applications for the 
L.O.C.PRO™ LP3-2.

Speaker Level Input to RCA Level Output

Speaker level input to RCA level output is the most commonly used scenario for the LP3-2.
Use this when you need to create RCA level outputs from a source that only has speaker level outputs. 
The RCA input connectors on the main harness will not be utilized for this type of installation, we suggest 
cutting them off the harness 3 inches from the RCA end so they can be saved and used for a future installation.       
After all the connections are made, skip to the level adjustment section of this manual.
