Speaker level input from a radio to RCA level output for an aftermarket amplier is the most commonly used conguration for the
L.O.C.PRO ADVANCED. This will create RCA level outputs from a radio that only has speaker level outputs.
In the example below, the Positive(+) and Negative(-) wires of two speakers are “tapped” and connected to the SPEAKER SIGNAL
INPUTS of the LPA. The speakers will continue to play as normal. The REM OUT is connected to the ampliers turn-on. When the
radio is turned on the LPA will automatically turn on the amplier. Lastly, the RCA SIGNAL OUTPUTS from the LPA are connected
to the aftermarket ampliers inputs.

Perform the following procedure for each LPA you are installing.
1. Start with gain adjustment levels on LPA set to minimum.

3. Turn source unit to maximum volume and start test track (1kHz for mid/high or full range, 100Hz for sub).
If Bluetooth is used as sou ce, make sur re the device volume is set to maximum.

7. Turn volume down and system off.

Basic method –
2. Turn head unit to ¾ maximum volume and play test track (Random Noise) or a familiar song that has
dynamic attributes.
For example, if your volume goes to 40 you will tu n it up to 30 and play a song that has somer
quiet sections and some really loud sections.
3. Slowly adjust f ont channel gain of LPA until just a hint of distortion is audible, and thenr
back down gain just under that th eshold and the distortion goes awar y.
4. Repeat steps 1-3 for rear channels.
