2018 JBL Tundra aftermarket amp issue

Hello, I have a 2018 limited crewmax Tundra and it has the factory JBL system and I want to add a aftermarket kicker amp and I have the amp bypass for the speakers all set the issue I’m having is the back of my factory stereo has zero RCA connections to connect to the aftermarket AMP and I have tried researching on how to fix that issue but the only thing I have read is a LOC converter which I still do not know where and how to wire those cables to a LOC converter, if anyone knows how to help this issue I’m having please let me know , thank you for reading God bless

If you haven't bought the LOC yet, I would look at the

$315 Rockford Fosgate DSR1 8-Channel Interactive Signal Processor w/Integrated iDatalink Maestro Module

Rockford Fosgate DSR1. It takes the place of the factory amp, plug & play, & it gives you RCA outputs for your aftermarket amp.

 

In all likelihood you do not need a LOC and can use high level/speaker level inputs on your amp. What do you mean by "I have the amp bypass for the speakers all set" and what model of Kicker amp are you looking to install?

The gist of what you need to do is use a factory integration harness at the factory amp location to grab your high level inputs, feed those into your new amps high level input section (or if it only has RCA's but accepts speaker level inputs get speaker wire to RCA adapters), and then again use the factory integration harness to tie into your amps output section and the factory wiring going to your speakers.
