We frequently receive questions around how to run an aftermarket amp with subwoofers alongside a Brainiac install. Specifically when in use with our Electronics kit. I figured this would be a good time to create an article that I can refer to for guidance on this type of configuration. Generally speaking the installation is very similar to any aftermarket head unit install with a remote amp for subs.
You’ll need to get an audio signal to the amplifier running the subs, and an audio signal to the amplifier running your cabin speakers. You’ll also need a remote amp signal wire to turn on the amp that powers your subwoofers.
